Very worthy plant for the foliage alone - the bloomstalks are merely a nice bonus (though you'll want to cut them shortly after they flop over to keep the plant from looking messy). Completely non-invasive but propagates very easily from divisions. I started with one 8 years ago and now have several (not including a bunch I gave away). Becomes noticeably less vigorous in its fifth season if not divided. Fast grower - in the right spot, it reaches full 4-foot+ diameter in its second season from a 2QT pot. Where I am, a bit of afternoon shade and fairly rich soil that stays reliably moist are perfect.
