Big Blue Liriope

Big Blue' Liriope (aka "monkey grass") is grown for its wonderful deep-green foliage which remains year-round and for its deep-purple flower spikes in July and August. Plant 'Big Blue' as a border or a mass-planting where you don't want plants to spread into surrounding beds. 'Big Blue' forms a clump - it doesn't spread by underground runners as does Spicata liriope. We cut down our liriope only once every 3 years to remove old foliage, either by hand with clippers or with a weed-eater. The best time to trim is right when you see new growth emerging in early spring, before it gets tall enough to interfere with trimming away the old foliage.
