Drew, is that one related to your P. McDowell ( ? or something ? ) that I have always liked so much. It is just stunning.
Maybe you should take one of the sprouts indoors and display it in a pot each winter as insurance - to make sure not to lose it if there is an extra-cold spell in winter? If it's the same one I am recalling, it looked magnificent in the pot before it started crawling out, too. You had it on a table in front of a small window . . . ?
If I had it, I'd keep one part in a pot, and bring it in for a house plant, it's so pretty.
