Liriope Spicata Hardiness in Zone 4
I would like to plant liriope spicata in my yard instead of grass. I recently bought my home on Higgins Lake (near Roscommon MI) which is in zone 4.
I had a very good experience with liriope in West MI (zone 6) as a ground cover. According to what I have read, liriope spicata is hardy to zone 4.
Because I am planning to plant several hundred square feet of liriope, I need to know if the plant is likely to survive northern MI winters. If so, do you have any tips to improve the chances that the plants will survive? Would it be best to plant in the spring?
