Q. Where can I find some winter-hardy variegated ivy?
Dear Gardener: I would call some of the nurseries in the Philadelphia area to see if they have the variegated ivy. Try Mostardi's Nursery in Newtown Square or Main Line Gardens in Malvern. Unfortunately, I don't know about nurseries in Center City, but sometimes florists shops have pots of ivy that they sell for gifts. They might be worth a try, but hardiness should be questioned!
Also try City Planter, located at 814 N 4th St, Philadelphia, PA 19123.
