Has any in zone 5 left calla lily bulbs in the ground and had the
Okay, my goal this season was to work on the flower beds in the front yard. But thanks to the weather,some other issues and very bad twisted ankle. I got started today and the weeds were not happy. I still have to plant the calla lilies that I started from bulbs in April. So image my surprise when clearing away some weeds to find a calla lily in the one of spots that I planted some last year. I thought I dug them all up. There is a small amount of mulch over the spot but I can't figure out how it survived the winter. Any ideas?
