I love these - only one place I know around here has them used in their landscaping and that's the local college - spotted them when I walked out of a meeting. Had to go get my camera - thanks for telling me what they're called.
i thought i've commented on this before but i guess i forgot to press that post comment button yet again. i like looking at horsetails. the only place i could find this is at the castle's garden uptown. i think they're a rather attractive plants. aces!
