Liriope muscari 'ROYAL PURPLE' border grass, lily-turf

Liriope muscari prefers partial shade to full shade and is highly tolerant of drought. It will be more lush in soil that can hold some moisture without staying waterlogged, though ordinary garden soil with a touch of humus is perfectly sufficient. We’ve found that it grows slightly better in acidic soils, with deeper green foliage, but it isn’t essential – it will manage almost anywhere, only perhaps a little slower. Its strong drought tolerance has become especially evident in recent decades, as rainfall decreases and older perennial species begin to show that the new conditions don’t suit them. Liriope copes well even in drier spots under the trees and between their roots, and in urban beds without irrigation, relying solely on whatever rain arrives. Conversely, if you water regularly or have irrigation, you can grow it in full sun. It doesn’t require feeding, but it responds quickly to nutrients with stronger foliage and more generous flowering. The leaves are left on through winter, though if they look tired and untidy by spring, they can be cut back to about 5 cm above the ground. This isn’t needed every year – once every few seasons is enough. Its hardiness reaches –29 °C (USDA zone 5), so in Central Europe it usually needs no winter protection, except for a light mulch in its first year. It can also be grown in outdoor containers with excellent drainage.
