Do you have a partially shaded area that you want to brighten up? May I suggest this: Ligularia stenocephala 'Little Rocket'. Good for zones 3-9. Very unfussy plant.. I got it last year as a 1 gal sprout and it's already coming back! In fact, only thing that's coming up faster than this thing are my columbines! Plus, where else could you find such big beautiful leaves with such bright yellow flowers.. in the middle of summer! Partial shade, NO full sun.. that cooks it. GREAT plant, if I may suggest! Don't know about butterflies or hummingbirds, when I got it, the flowers were almost 100% kaput and my hummers go for my hyssops anyways.

Here's a stock photo.. I'm planning on taking lots of pics of this baby when it gets bloomin'!
