I think this is a bush, but I'm not sure. It has orange flowers that bloomed in July. Hummingbirds love it.

  • Hey thanks! But this is considered a woody 'based' perennial. (never heard that term before)...

  • Ya, the reason I thought it was a bush is because it's woody.

  • @stormy That's because it doesn't die all the way back on it's own. I usually take them back farther than they naturally die.

  • They don't die back to the ground, they maintain a viable vascular system beneath woody cambium during a winter. The best time to prune these guys is AFTER the winter and just before spring. The old wood, dead branches/leaves actually help hold onto snow for insulation to ensure survival. Wait 'till spring to cut back, yes? Grin...

  • So should I prune them all the way down to the ground?
