Also known as giant lily turf, giant liriope (Liriope gigantea) is a grass-like member of the lily family that grows to a height of about 3 feet. The grass flowers in the summer, producing white or lavender blooms that are followed by small purple fruits. Giant liriope and its cultivar, the variegated "Variegata," are prized for their low care requirements.
Hardiness
A native of Japan, giant liriope is a temperate-loving plant suitable for USDA zones 7 to 10. The plant is approximately hardy to 0 to 10 degrees F. Liriope is tolerant of a range of light conditions, growing in full sun or partial shade. In the southern end of its region, giant liriope may be grown in light shade. Plants grown in full sunlight will produce more flowers than those grown in shadier conditions.
Location
Giant liriope works well as an edging plant or as an accent in an Asian-inspired garden. When planting, place plants about 1 foot apart. The grass is tolerant of sandy soils as well as heavy, clay-based soils. Though tolerant of salty soils and drought, liriope prefers a soil that is consistently moist and well draining. Giant liriope will rot if grown in soil that is consistently flooded or waterlogged.
Maintenance
Giant liriope is a durable plant that requires very little maintenance to look its best. Remove spent foliage in late winter, before new leaves appear in the spring, to keep the plant looking tidy. Though division isn't necessary for the plant's health, liriope may be divided every few years in early spring if more plants are desired. Plants grown in full sunlight will require more frequent watering than ones grown in partial or full shade.
Problems
Giant liriope is susceptible to anthracnose, a fungal disease that causes unsightly brown spots to appear on the tips and margins of the plant's leaves. Prevent the disease by mowing dead leaves away in late winter and removing all plant debris from the area. Do not water late in the day because wet leaves are more susceptible to fungus. Overwatering can also lead to fungus. When mowing, mow on the highest setting the lawn mower allows to avoid injuring the grass's crown.
