What do I have here?

What do I have here?

I can't resist buying perennials at garage sales when they're only $1 each (or sometimes less). I came home with two today, and the woman didn't know what they were. I feel like I should know the first one (with yellow buds) but am clueless about the second. If they were in bloom, I'd have an easier time finding them in my books or online. The first one is a kind of wispy plant, 18+ inches tall. The second is only about 10 inches tall. Any help is appreciated.
