Becky - have you ever been to Rock City Gardens, on US 1. I believe it is just south of Sebastian. I could be wrong and it could be just north. It's been a while since I visited the nursery - which I really like as they have a lot of unusual plants. Anyway, they have a massive pony tail in the ground. I don't have a picture of it, but I'll try to remember to do so next time I visit. I have never seen such a huge specimen.
