Scirpus lacustris cv. Spiralis
Juncus effusus f. spiralis

Juncus effusus

Juncus effusus

Distribution and habitat: Juncus effusus is cosmopolitan rush species that occurs in most temperate world regions, including North America, Europe and Asia; moreover, the plant also can be found in many montane-tropical regions. Its habitats are diverse, but often feature moist areas at forest margins, wet grasslands, wetland margins, lake shores, river banks, and in fen-meadows.

Description: Juncus effusus  is a clump-forming perennial that spreads by both short rhizomes and seed. The clumping plant manifests stout but supple stems that may reach 1.5m (5 feet) in height. The stems are smooth cylinders with light pith filling. The lower leaves are reduced to a brown sheath at the bottom of the stem. The yellowish inflorescence appears to emerge from one side of the stem about 20cm (8 inch) from the top. In fact the stem ends there; the top part is the bract, that continues with only a slight colour-band marking it from the stem. Juncus effusus has 30 to 40 ridges on the stem. Seed production is extremely high with each shoot capable of producing 8,500 seeds per year.

Gardening: Juncus effusus  are maintained by the removal of old stems in spring. If this plant dies down in the winter (in cold climate conditions), room for new growth is made by pulling up and discarding the old, dead stems. Leaving the old stems will not harm the new growth, but it can become messy.

Though initially slow to establish, Juncus effusus has tough, aggressive underground roots that will help the plant spread over time. The plant growth can be controlled by growing it in a shallow container without drainage holes into the mud, leaving a few inches of water above the container or sunk the container into a pond.

Position: Though tolerant of a little shade, Juncus effusus is a sun-loving plant that will produce its best growth in a location with full sun.

Soil: Juncus effusus thrives in acidic, wet soils that have poor drainage.

Irrigation: Plants require permanent water, ideally between 5 and 10cm (2-4 inch) deep, it can be grown near water with pebbles and rocks or with continual irrigation.  It is a tough plant that can withstand brief periods of drought, but it will become brown and unsightly if left without water.

Fertilisation: An application of diluted liquid fertiliser to half strength is recommended at the time of transplanting and monthly throughout the growing season.

Recommended varieties:
Juncus effusus cv. Spiralis (Corkscrew Rush, Spiral Rush) is perennial wetland plant. This plants grow in both a horizontal and vertical direction. Its bright-green, cylindrical stems, which are hollow, form tight spirals. As the stems lengthen, the spirals uncoil somewhat and stretch in every direction, forming a captivating untamed mass. Juncus effusus cv. Spiralis will reach a height of 0.45m (1.5 feet) and a spread of 0.6m (2 feet) after two to five years. Plants may flower in summer, but the inflorescences, range from yellow-green to brown and are small and nonshowy. It is a popular ornamental water plant due to its tortuous spiral like foliage.
Ideal for bog edges or standing water up to 10cm (4 inch) deep, this grassy perennial features clumps of cylindrical stems is suited to container cultivation and can be used as a houseplant.

Houseplant care: Indoors, Juncus effusus cv. Spiralis is planted in a water-retentive potting medium in containers with no drainage holes.
Old stems, which turn brown, may be snipped with scissors. In spring, the wild stems can be tamed with trimming as desired; this will also make room for new growth.

Light: As long as the roots are able to sit in shallow water, Juncus effusus cv. Spiralis can tolerate full sun, but partial shade is ideal for this plant when it is displayed indoors.

Temperature: Outdoors, this plant is a rather hardy selection and, as a houseplant, can tolerate a range of temperatures, but 16 to 24°C (65-75°F) is ideal.
Although Juncus effusus cv. Spiralis loves a moist environment, moisture in the soil is much more important than moisture in the air. Spray misting this plant is not required.

Watering: Because this is a marginal aquatic plant, soil should be kept moist at all times. To ensure constantly moist soil, pots that have drainage may be partially submerged into another container filled with water, replicating the bog-like conditions in which this plant naturally grows.

Feeding: Apply a balanced liquid fertiliser at half strength once a month during the growing season.

Potting and repotting: Healthy plants will expand, so annual division and repotting is often necessary. Repot the new divisions in containers without drainage using a neutral to acidic potting soil.

Problems: Juncus effusus cv. Spiralis is typically unaffected by pests; instead, the most common problem associated with this houseplant is improper watering and soil conditions.

These plants prefer excessively moist soil; what would lead to root rot in most houseplants are conditions under which this plant is kept.

Propagation: Propagation is by division the rootball of plants in mid to late spring. Lift and divide the clumps  using a sharp knife to sever tough rootstocks. Replant (repot) the new plants immediately.

Plants will also naturalize by self-seeding.

Notes: Both, Juncus effusus and Juncus effusus cv. Spiralis can self seed and become unruly weed in some areas. It is often planted in submerged containers to prevent it from invading and overtaking the landscape.

Uses: Juncus effusus and Juncus effusus cv. Spiralis can be grown at the edge of a pond or water garden, in boggy areas, among wet pebbles or rocks or in low deep standing water. They make a good water garden accent. Add a certain amount of authenticity to transitional waterside areas. They are effective in containers and Juncus effusus cv. Spiralis become a popular indoor plant.

Juncus species can be grown on the edge of waterbodies to help control erosion.
Juncus effusus and Juncus effusus cv. Spiralis stems are used in floral arrangements.

Height Juncus effusus: 1.5m (5 feet)
Height Juncus effusus cv. Spiralis: 30-45cm (12-18 inch)

Phormium tenax

August 28th, 2013

Common name: New Zealand Flax, Flax, New Zealand Hemp, Flamin

Family: Xanthorrhoeaceae

Phormium tenax

Phormium tenax

Distribution and habitat: Phormium tenax is an evergreen perennial plant native to Phillip Island and indigenous to New Zealand, Norfolk Island and the Chatham Islands. It is an important fibre plant and a popular ornamental plant.

Phormium tenax is a coastal cover plant associated with significant habitat such as the breeding habitat for the endangered yellow-eyed penguin.

It is an invasive plant in many parts of the world and is proving a threat to sensitive floras.

Description: Phormium tenax are dramatic, architectural plants with a fountain of bold strap-like leaves and semi compact habit. The plant grows as a clump of long, strap like leaves, up to 80-90cm (31-35 inch) long, from which arises a much taller flowering shoot with sword-like form and dramatic yellow or red flowers. The leaves are coloured in tons of olive green, red, orange and bronze as it matures.

Phormium tenax are frequently used for spiky, sword-like form and a variety of colors, including greens, reds, copper and yellow, but are seldom recognized.

Gardening: Phormium tenax has medium to fast growing rate. They are perhaps the most versatile container grass-like plant to design with. It tolerates warm-temperate, temperate, cool-temperate climates – frost tolerant.

Avoid planting Phormium tenax during humid mid summer conditions. The base of the plant should be clear of mulch or soil build up to avoid plant rot. Remove spent leaves and old flower heads as required. It has low maintenance requirements once established.

Position: Phormium tenax tolerates a full sun to semi shaded position. It tolerates coastal conditions (it is tolerant of salt air) and moderate frost.

Soil: Suitable for most soil types. In more humid areas care should be taken to plant in well drained soils.

Water: They are generally tough plants that will endure hot dry positions once established, though their preference is for moist but well-drained soil. Apply mulch to reduce weed growth and keep the root zone cold and moist during dry periods, particularly for young plants.

Water as required for 8-13 weeks until established, then water as required. Once established it has a medium water requirement and responds to occasional deep watering .

Fertilising: Apply to the soil surrounding the plant a long term slow release fertilser at the end of winter. In the spring use a fertiliser rich in nitrogen and potassium to encourage the development of new vegetation and of flowerings.

Propagation: Phormium tenax is propagated from seed or clump division. The seeds remain viable for about 12 months when are stored adequately.

The seed is best sown as soon as it is ripe in a cold frame. Sow stored seed at the end of winter in a cold frame. Germination is sometimes poor but should take place in 1 – 6 months at 15°C (59°F). The seedlings are very variable. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.

Division in spring as growth commences. Larger divisions can be planted out direct into their permanent positions. Pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Toxicity: The blades of the plant contain cucurbitacins, which are poisonous to some animals and some of them are among the bitterest tastes to humans.

Problems:
Leaf spotting fungus sometimes occur.
Treatment: To combat leaf spotting use a recommended fungicide according to label directions.

Slugs and mealybugs sometimes attack the plant.
Treatment: Use a recommended pesticide according to label directions.

Uses: Phormium tenax is planted in small gardens or in containers for color contrast. It is suitable for low maintenance gardens, rockeries and ornamental gardens. It is great around pools or ponds, as well as in pots. It works well in mass planting.
Phormium tenax is usually used as roadsides plants, mass plantings, feature plantings and plant gardens such as sunny edge of woodland garden, bog garden or cultivated beds.

Phormium tenax it is a great garden companion for plants like Pinus (pine), Cotinus (smokebush), Aster species.
Phormium tenax can be used as a colourful garden container in association with plants like Scirpus cernuus (Fiber optic grass),  Heuchera hybrids (Coralbells), Pelargonium variegated hybrids (Variegated geranium), Citrofortunella microcarpa (Calamondin).

Carex morrowii Variegata

July 30th, 2013

Common name: Silver Variegated Japanese, Japanese Sedge Grass

Family: Cyperaceae

Carex morrowii Variegata

Carex morrowii Variegata

Distribution and habitat: Carex morrowii Variegata is originated in woods from low mountains in Japan.

Description: Carex morrowii Variegata is a clumping, evergreen variegated sedge. This stiff, grass-like sedge will contrasts well with broad-leaved plants. Its clustered leaves, which grow from a rhizomatous rootstock running just below the surface, are up to 30cm (12 inch) long and very narrow. Leaves are yellowish green narrowly striped with white. Flowers are insignificant.
This plant grows more or less continuously, but attractive growth will slow down in the reduced light of the winter.

Houseplant care: Carex morrowii Variegata is a moderate grower and is often used in association with other species to add contrast in shape and colour of the display. When plan to create displays using Carex morrowii Variegata, choose plants needing similar life conditions such as Scindapsus and Maranta species.

Light: Grow the Carex morrowii Variegata in bright filtered light. Inadequate light will dull leaf-colour contrast.

Temperature: Carex morrowii Variegata can tolerate warmth 18-21°C (64-70°F), only if humidity is kept high.

In warm rooms is advisable to stand plants on trays of moist pebbles and mist-spray them regularly. If possible keep winter temperatures down to 10-15°C (50-59°F).

Water: When grown indoors Carex morrowii Variegata should never be overwatered. Throughout the year water moderately, enough to make the mixture thoroughly moist, but allow the top 2cm (0.8 inch) of the potting mixture to dry out completely between waterings.

Fertilising: Apply standard liquid fertiliser once a month during spring and summer only.

Potting and repotting: Use a soil based potting mixture. A 13cm (5 inch) pot is likely to be the biggest pot size required. Move small plants into pots one size larger whenever the tufts of leaves completely cover the surface area of the potting mixture.

Gardening: Carex morrowii Variegata is an hardy evergreen for hardiness zone 5. It is adapted to chalk, clay loam, loam, loamy sand, peat, sandy clay, sandy clay loam, sandy loam, silt loam and silty clay loam soils and prefers high fertility. It should be placed in partial shade. It will grow in full shade and even tolerates full sun in cool climates. Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. It spreads slowly by rhizomes and is quite drought tolerant once established. For a neat appearance, remove old foliage in late winter or early spring, before new growth emerge.

It is seldom necessary to divide clumps, unless more plants are desired. Divide and replant every 2 to 3 years in early spring.

Propagation: Split the mature plants into two or three clumps and plant each separately, preferably in spring. Do not divide a plant into more than three sections; very small clumps rarely grow into healthy plants.

Uses: Carex morrowii Variegata is wonderful as a ground cover especially under trees or as border edgings. It is most effective when grown in large clumps or massed plantings. It is an useful sedge for erosion control, rain garden, rock garden or will naturalize spaces. Makes also an attractive specimen plant or ground cover as waterside plants like Heuchera, Canna, Astilbe, Iris and Tiarella species, especially those with contrasting purple foliage. Create an exotic Asian garden with Acer palmatum (Japanese Maple), Athyrium niponicum (Japanese Painted Fern), Lilium asiatic (Asiatic Lilies) and Peonies species. It is an attractive addition to low lying wetlands, streambeds or near ponds and water features.

Carex morrowii Variegata is the only one from its large genus widely grown indoors being an attractive container plant.

Height: 30-45cm (12-18 inch)
Spread: 45-60cm (18-24 inch)
Hardiness zone: 5-9

Calamagrostis x acutiflora Karl Foerster

July 23rd, 2013

Common name: Feather Reed Grass

Family: Poaceae

Calamagrostis x acutiflora Karl Foerster

Calamagrostis x acutiflora Karl Foerster

Description: The most popular ornamental grass, Calamagrostis x acutiflora has a distinct upright habit that looks fantastic all winter long. Calamagrostis x acutiflora ‘Karl Foerster’ it is a hybrid which is valued for its early bloom, vertical lines and ability to grow in wet soils. It is a slowly-spreading, clump-forming, cool season ornamental grass which features an erect, slightly arching, slender clump of narrow, stiff, rich green leaves growing to 1m (3 feet) tall and 45-60cm (18-24 inch) wide. Leaves produce little fall color, eventually turning tan in winter. In spring, tightly-vertical flower stalks rise well above the foliage up to 1.8m (6 feet) tall bearing narrow plumes of feathery, purplish-green flowers which turn golden as the seeds mature in summer and eventually tan. It is one of the first ornamental grasses to bloom in spring.

Gardening: Calamagrostis x acutiflora Karl Foerster is fast growing hardy perennial and like many grasses, this tough plant tolerates a wide range of conditions. It is sterile, so mass planting can be done without fear of becoming invasive.

Cut clumps to the ground in late winter just before the new shoots appear. By cutting it in fall, you may miss the nice winter appearance of this stunning ornamental grass. Cut it back to about 6cm (6 inch) from the ground. Plant or divide them early to late spring and early fall. If applicable, plant it at the same depth as it is in the pot. Recommended spacing between plants is about 45-100cm (18-40 inch).

Calamagrostis x acutiflora Karl Foerster are clump forming, rather than spreading by rhizomes. They will eventually need to be divided in fall or early spring, generally every 3 to 5 years, to prevent them from dying out in the center.

Position: Calamagrostis x acutiflora Karl Foerster thrive in sun to light shade positions. Blooms in light shade and appreciates some light afternoon shade in hot summer climates.

If grown in too much shade, Calamagrostis x acutiflora Karl Foerster will be smaller and flop a bit.

Soil: Grows in moderately fertile, moisture retentive soil. It grows quite well in moderately heavy soils, but they must be moisture-retentive and not dry out.

Water: Calamagrostis x acutiflora Karl Foerster can grow in fresh-water bogs, it also does well in drier areas. Water to root depth once every 2 weeks for best results.

Once established,Calamagrostis x acutiflora Karl Foerster is drought tolerant. It will be a smaller plant if grown in a dry site.

Fertilising: Fertilizer may be required to produce maximum height. Use a slow release, medium-rate fertiliser.

Propagation: This grass will not self-seed in the garden because seeds are sterile. Calamagrostis x acutiflora Karl Foerster can be propagated by division of clumps in mid-spring every few years.

Container plants: Calamagrostis x acutiflora Karl Foerster has wonderful, tall flower plumes that create an eye catching focal point when grown in a container. Although Calamagrostis x acutiflora Karl Foerster needs a bit of protection from the hot sun, it can survive winters in containers down to hardiness zone 6.
It is suited to grow in 18-20cm (7-8 inch) pot, 22cm (8.5 inch) pot or 25cm (10 inch) pot – any size will work well.
Soil: Use a soil based potting mixture for Calamagrostis x acutiflora Karl Foerster.
Light: Calamagrostis x acutiflora Karl Foerster will thrive in full sun or better in partial shade for the hot and dry climates.
Water: Calamagrostis x acutiflora Karl Foerster require to be evenly moist.
Fertiliser: Apply standard liquid fertiliser once every two weeks, from early-spring through summer.

Uses: Calamagrostis x acutiflora Karl Foerster looks good either as mass, group or specimen plant. Excellent vertical accent for borders and for narrow spaces in the landscape. Also effective in moist low spots or on pond or stream banks. It is suitable for architectural, cottage or informal garden, flower borders and beds or prairie planting. Plant it ‘en masse’ to form a feathery screen. It also looks good planted next to buildings.

Calamagrostis x acutiflora Karl Foerster is used as a backdrop for roses and other perennials, in arrangements.

Leymus arenarius

July 23rd, 2013

Common name: Blue Lyme Grass, Lyme Grass, Sea Lyme Grass, Sand Rye Grass

Family: Poaceae

Synonymous: Elymus arenarius

Leymus arenarius

Leymus arenarius

Distribution and habitat: Leymus arenarius is native to Europe and was naturalised in Asia, Australia, New Zealand and North America. Leymus arenarius is an invasive grass of coastal beaches and dunes where it appears to be spreading quickly and outcompeting the native flora in regions were the plant was naturalised.  Often it appear  in association with Ammophila arenaria. It is well known as an important species in the stabilisation of mobile dunes and widely planted as a sand binder.

Leymus arenarius is a perennial growing to 1.2m (4feet) by 2m (6feet) spreading at a fast rate. It is not frost tender. It is in flower in early summer and the seeds ripen in autumn. The flowers are hermaphrodite (have both male and female organs) and are pollinated by wind.

Description: Leymus arenarius is a vigorous deciduous to semi-deciduous stoloniferous grass with 60-90 cm (23-35 inch) tall in culture with upright blue-gray blades and spreads wide by rhizomes. His blue-gray wide, ribbon-like foliage often turns tan in fall.

Grown for its display of exceptionally beautiful steel-blue foliage, this is a spreading grass that needs to be used carefully. Arching spikes appear in summer, blueish at fist, that fade to cream. The flowers are not ornamentally significant and sometimes are removed in summer. Leymus arenarius can spread too quickly in a sunny garden bed. Planted in a container you still get the imposing sword shaped leaves that bend as they grow tall and develop the spiky flower heads. It is a cool season grass but tolerant of hot weather. It can become invasive.

Leymus arenarius reaches the maturity in 2-5 years and under ideal conditions can be expected to live for approximately 10 years.

Gardening: Leymus arenarius can tolerate maritime exposure and it is highly tolerant of urban pollution. It will even thrive in inner city environments. It has a fast growth rate.

Cut back the old foliage to the ground in late fall or early spring to encourage new foliage and keep plants fresh looking with good blue colour.

Position: Leymus arenarius can be placed in full sun or light shade. It will cannot grow in the shade. Plant it in full sun and give average to little water .

Soil: Leymus arenarius is suitable for light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. It is suitable for either acid, neutral and basic (alkaline) soils. It is able to handle environmental salt.

Water: Leymus arenarius is very adaptable to both dry and moist locations and should do just fine under typical garden conditions. Established plants are very drought tolerant.

Fertilising: Fertilising is generally not needed. Fertilizer causes lush growth that requires more water. If fertilization is needed, a slow release fertilizer can be applied in the spring.

Propagation: Clumps are easily divided in spring or summer. Even small root pieces will grow. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Leymus arenarius can be propagated as well by seed. Sow them in mid spring in site. Just cover the seed with a thin layer of sand. Germination should take place within 2 weeks. If the supply of seed is limited, it can also be sown in mid spring in a cold frame. When large enough to handle, prick the seedlings out into individual pots and plant them out in summer.

Note: Leymus arenarius is a very invasive plant, spreading by means of its wide-ranging roots.

Uses: Leymus arenarius is used as an accent plant or a ground cover. It is good for erosion control and sometimes is used to stabilize sand dunes. Will tolerate beachside conditions. Best to contain this in a planter, or use as a groundcover in a large sunny area.

It looks its best when allowed to ramble among other perennial plants in a natural style border where its foliage is combined with flowering plants and is particularly successful in a modern prairie-style planting scheme where a mixture of fairly vigorous perennials are planted as a tall carpet punctuated by paths. It is considered to be drought-tolerant and thus makes an ideal choice for a low-water garden or xeriscape.

Looks stunning in borders and makes a spectacular container plant for a sunny patio.

Foliage of Leymus arenarius is terrific for flower arranging.

Height: 60-90 cm (23-35 inch)
Spread: 60-90 cm (23-35 inch)
Hardiness zones: 4 – 9

Acorus gramineus

July 18th, 2013

Common name: Grassy-Leaved Sweet Flag, Dwarf sedge, Japanese rush, Japanese sweet flag

Family: Acoraceae

Acorus gramineus

Acorus gramineus

Distribution and habitat: Acorus gramineus is native to Japan in eastern Asia, where it usually occurs in wetlands and shallow water. It can grow fully or partially submerged or in very moist soil, but it will usually only flower when at least partially submerged.

Description:  Acorus gramineus narrow leaves, which grow in a dense clump or tuft rising from a slender rhizome that lies just below the surface of the potting mixture, are up to 45cm (18 inch) long. There is a green slower spathe, but is is barely noticeable since it is so fine that it looks almost like another leaf.

Houseplant care: Acorus gramineus grow more or less continuously, but its active growth will slow down under reduced light.

Light: Medium light or direct sunlight filtered through a translucent blind or curtain will suit Acorus gramineus.

Temperature: An indoor Acorus gramineus will grow well in normal warm room temperatures, but can also tolerate temperatures as low as 4ºC (39ºF). High humidity is essential; stand plants on trays of moist pebbles throughout  the year and mist-spray the leaves during the warm periods.

Water: Because they are marsh plants, Acorus gramineus needs more water than most other types of plants. These plants must never be allowed to dry out at the roots. Water plentifully as often as necessary to keep the potting mixture thoroughly moist. The pot may even  be allowed to stand in shallow saucer of water.

Fertilising: Apply standard liquid fertiliser every two weeks during spring and summer.

Potting and repotting: Use a soil-based potting mixture. In spring move small plant into pots or shallow pans one size larger if their tufts of leaves have completely filled the surface area of the mixture. 13cm (5 inch) pots or half-pots are likely to be the largest size needed.

Gardening: Acorus gramineus when grow outdoor is easily grown in average, medium to wet soils in full sun to part shade. Grows well in both boggy conditions (including very shallow water) and consistently moist garden soils. Scorched leaf tips will occur if soils are allowed to dry out. Appreciates some relief from hot summer sun (e.g., afternoon shade or filtered sun) when grown in hot summer climates. Slowly naturalizes by spreading roots, but is not too aggressive.

Acorus gramineus can be planted in baskets in shallow water. It also makes a useful aquarium plant but is short-lived where water temperatures exceed 22°C (72°C) for long periods. Divide every few years to prevent congestion.

Propagation: Prapagate by separating overcrowded clumps in spring or summer. Carefully pull the clumps apart with the fingers, making sure that a piece of rhizome is attached to each section and treat each divided clump as a mature plant.

Problems: Acorus gramineus has no serious insect or disease problems.

Scorch will occur if soils are not kept consistently moist to wet.

Recommended varieties:
Acorus gramineus ‘Variegatus’ is a variegated-leaved form of Acorus gramineus. It has white stripes on its green leaves.

Acorus gramineus ‘Albovariegatus’ is a variegated-leaved and dwarf form of Acorus gramineus. Its leaves grow rarely much larger than 15cm (6 inch).

Acorus gramineus ‘Ogon’ (Golden dwarf sweet flag) is a dwarf cultivar if Acorus gramineus to 25cm (10 inch) tall and 15cm (6 inch) wide. It has linear fans of glossy, pale green and cream-striped leaves that have an overall golden effect.

Uses: Acorus gramineus can be used as groundcover, in erosion control, rain garden or as a water plant.

Acorus gramineus are generally paludal (marsh plants) and are equally suited to aqua-terrariums and garden ponds, although they will also survive totally submerged.

Acorus gramineus can be used to form mass as ground cover in small areas of water gardens, along streams or ponds or in moist open woodland gardens. It is frequently used around the edges of ponds and water gardens, as well as submerged in freshwater aquaria. Acorus gramineus is ideal for foregrounds in aquariums. Also effective in rock gardens or border fronts or as small landscape accents as long as the soil moisture requirements can be met.

Acorus gramineus is the only one species from genus Acorus often grown indoors. Acorus gramineus provide a pleasant contrast with the more substantial foliage of other house plants.
