Thought I would start a thread on this since it seems like we all do it. Here in zone 5a, from the approximately 135 different kinds of hostas I have in my yard I'm still waiting for:
Dragon's Eye (new in 2009)
Thunderbolt (new in 2009)
Foxfire Shadowdancer (new in 2009)
Bunchoko (new in 2009)
Mountain Mist (I think this one died last summer, I stepped on it about three times)
Earth Angel (was late coming up in 2009)
I think my winner for biggest multiplier over winter will be Arctic Blast, went from one puny new eye in 2009 to it looks like at least 6 eyes this year! There are some I just have not looked for yet, so I don't have them in the list above.
Who else is doing the kneel and feel? What is it that you are still waiting for?
