Yep, I did know that! Just gots to be careful-the new flower stalk is forming within a portion of the old, kind of a zig-zag effect. If one is overzealous and cuts that whole thing off, well, then not so much, as far as repeat blooming. Leastways, that's how it goes up here in summer.

Yes, you are right. I guess I didn't make it clear, you need to cut off just below the last flower. :o) The new flower forms on the same stalk. Here in S Fl I grow them all year long.
