I just stumbled on your post from several months ago. I'm kind of new to hostas, and my interests are fairly specialized (mini hostas for limited space), but here are a few I came up with:
A Many Splendored Thing
Banyai’s Dancing Girl
Lakeside Cupid's Cup?
Kiwi Blue Baby
Love Pat and Abiqua Drinking Gourd are very similar. Big Daddy is in the same colour range, but more mildly cupped for me.
Maui Buttercups is a smallish gold, also moderately cupped.
I got a Deep Pockets this year as it's supposed to be extremely cupped and dark green. It's too small yet to show any cupping but I think I'm gonna love it.
Rosedale Spoons is showing it's cupping already and it nice and shiny. Love this one already.
Teaspoon is a small cutie patootie with tiny cupped leaves.
Those are the only ones I have. I love how the water pools in the big cups after a rain. They catch other things too, though, like tree and shrub debris. I moved my Love Pat last year because it was under a shrub rose that would shed petals and hips ... and Love Pat would be like a big ole catcher's mit underneath! lol
It's very hard to photograph a black cat at night, but I just had to try and get this. This large cupped hosta (NOID) had it's cups full of water after the sprinkler had been running, and my cat Buddy just had to get a drink out of each of the cups.
It's too big to be Love Pat. I think that I remember my mom telling me that it either had "blue" or "big" in it's name. Neither one of us can remember the name any more, and it was one of my first hostas and I didn't have a tag.
