Are callas winter hardy there, or do you take them in? They do fine here, but I assumed Zone 7 was about the limit of hardiness for them. Mine grow so well that I need to dig and thin them every few years. I give them a feeding in spring, along with everything else, and massive amounts of water when they're growing. They thrive alongside my iris and Eucomis, but will tolerate more shade and wetness than the iris. The big bonus for me is that deer won't bother them.
BTW, I developed a really cute hybrid of Pinellia tripartita, with chartreuse/variegated foliage and a red spathe. Unlike most jack-in-the-pulpits, it grows from a rhizome and blooms continuously in spring/summer. Plant Delights got it from me and occasionally has it for sale. My mother plant is P. tripartita 'Free Tibet' and I have a seedling population now. Once I got both traits in one plant, many of the seedlings look like their mom! It's native to Japan and hardy to Zone 4 I think. If you want one to try, send me your address.

Hi Bob,
Thank you for posting your thoughts about the calla lily leaf coloration and
the additional info. It is very reassuring and helpful. (I love caladiums by
the way, but only grow them in a planter box in the summer.) I'm going to
move the lily out of exile now :)
