Q.Double flower Calla Lilies
I have a pretty good size area with deep purple variety of calla lilies. I dig up the bulbs fall and replant in the spring.
I have several deep purple calla lily plants that appear to have two flowers growing from one stem. I first noticed a couple last year. This year I have a few more. Is this unusual?
It is unusual but not uncommon. Does that make sense? I have seen pictures posted online with this alteration and have seen it in my own garden. We've all seen blooms that failed to open; something went wrong in the process. Duplicate calla lily blooms are also something that went different but, in this case, it is a pleasant change. A "sport" is a plant that undergoes a desirable genetic change. Plant breeders and plant enthusiasts cherish these special plants.
