Sandra I probably have some plants. I have to do some work in the greenhouse at some point this week and I'll take a look. I grow it as an annual or a biennial here. It will often remain green over the winter and start growing in the spring if I have it in a protected area. I just cut it back when it starts going to seed and it keeps growing. It's also a great host plant for swallowtail caterpillars. I'll let you know if I have any left.
