Lyre-Leaved Rockcress

Arabidopsis lyrata subsp. lyrata

Lyre-Leaved Rockcress (Arabidopsis lyrata subsp. lyrata) is a low-growing, herbaceous perennial native to temperate grasslands of Europe and North America. It has an upright growth habit, forming a neat clump of dark-green foliage and has fern-like leaves that form thin, delicate fronds. In the spring, Lyre-Leaved Rockcress produces delicate white, yellow, or cream flowers that cluster together on a single stalk. It is well-suited for use as a ground-cover or in a rock garden, and can also be grown successfully in containers. In addition to its attractive foliage and flowers, Lyre-Leaved Rockcress is also a popular choice for a foliage plant in flower gardens due to its low maintenance requirements and drought-tolerance.

watering

Generally speaking, Lyre-Leaved Rockcress (Arabidopsis lyrata subsp. lyrata) prefers moist soil and needs to be watered regularly during its active growing season. In areas that experience periodic dry spells, it should be watered regularly but not be allowed to become saturated or waterlogged. During the hottest and driest parts of the summer, the soil should be checked every few days for signs of drying out, and watered accordingly. Consequently, it should be watered more often during dry heat and less during cooler weather. In the winter, watering can be reduced to once every few weeks or even less.

sunlight

Lyre-Leaved Rockcress (Arabidopsis lyrata subsp. lyrata) is a plant species that prefers to grow in mostly sunny sites, and may even require full sun in order for it to thrive. It prefers at least 6 hours of direct sunlight a day in order to maximize its growth. Too much sun can lead to sunscald on the leaves and potential damage to the plant. If it is grown in less sun, then its growth will be stunted and it may not flower as well.

pruning

Lyre-Leaved Rockcress (Arabidopsis lyrata subsp. lyrata) is best pruned in early spring before bloom and should be pruned lightly. Pruning of this plant will encourage healthy, robust, branching growth and also limit the spread of disease. When pruning, cut back unhealthy stems at the right angle, just above a pair of healthy buds or a healthy pair of foliage leaves. Make sure to take off no more than 1/3 of the plant's total growth. Clipping off old flower stalks, seed capsules, and stems will increase air circulation and help reduce fungus problems. Prune as needed and be sure to dispose of all clippings properly.
