Thanks Karen! That was very helpful! I'm pretty sure the one on my porch is Russian Red (sister gave it to me, she threw out the tag when up potting), and the ones in community garden are a smaller, light green (? blue) variety, grown by a local agricultural school. (again, no tags)
The community garden is locked up in the fall, and the town won't open it til the end of May, in spite of the past 2 years, our trying to educate the decision makers, who are not gardeners. So not sure what to do in fall. Bring them all home, or put them all in garden and hope for a late spring crop?
