My neighbor brought me a ton of these last year from a lot he was clearing off. Blooms stood at least three feet, huge clumps growing w/ no care in dry sand, covered in leafy mulch, and gorgeous. I trimmed and planted them right away, and this year they have bloomed like crazy. Wonderfully fragrant, lovely cut flowers for the house.

This one is a survivor that was here 35+ years ago when I move in. It has PBF - delicate purple coloration at the bottom of the stalk.
