I would just like to add a note to Glen's. I had Eucomis autumnalis, E. bicolor, E. bicolor 'Alba', E. comosa, and E. pole-evansii in the ground one or two seasons before moving the nursery, and I sensed only some loss, or needed recovery time, in the E. bicolor group. My Eucomis were under a 2-4" coarse hardwood mulch in full sun. We don't usually have snow blankets to rely upon in this zone 6 region. I have replanted but have no results to share at the new location, yet. I will be removing my E. vandermerwei from the nursery based on the comments in this thread. I just have too few to risk it. E. montana is also in the ground, now. Mr. Kelly M.
