The butterflies are mad for lantana. Lantana, here represented by the delightfully perennial 'Miss Huff', isn't supposed to be 8 feet I think, but this year it's gotten huge and eaten all the plants we thought would make a lovely border around it. Of course we could prune... but then we'd have to get close to it and it might eat us. Blue salvia's another perennial and favorite butterfly food.
The butterflies don't seem especially excited about the rudbeckia, but I like them well enough.
