I'm not all that impressed by Echinacea in general. Unlike certain people, I think the weird cultivars have more going for them, just by virtue of not being just another in a long line of vaguely daisy-like plants. Nothing against daisies, but, you know, I've seen them before: I'm not impressed.
("It is not modern enough, the sound the wind makes stirring a meadow of daisies: the mind cannot shine following it." -Louise Glück, "Daisies," in The Wild Iris)
Also I'm not nuts about Echinacea because I don't like how they poke me when I'm trying to move them around or groom them or whatever. But I suppose they're better than some things.
