Liriope Royal Purple is hardy and tough perennial evergreen foliage. It produces rich deep purple flowers in the summer and blackberries in the winter. The clumps of the plant spread fast, ideal for deep ground cover, borders or mass planting. It likes full sun, very cold or shady areas. Liriope is very tolerant to humidity, summer heat and dry periods. If the plant looks shabby, the tip of the leaves can be trimmed with scissors or can be just cut down. The plant should be well watered and well-fed with a controlled release fertilizer after flowering for best results.
