Summer Sky was very beautiful.. and Summer Glow actually was a very nice yellow!
I have either Summer Fiesta or Raspberry Summer growing right now. I don't know which it is as the tags got removed as I thought they died. I have to wait until they actually start blooming to figure it out.
Kermit - The Acapulco series, Agastache rupestris (Sunset agastache), & Agastache cana do extremely well in my zone 5 climate. The Nectar series (Grape & Orange) *are* perennial here as well, but aren't as vigorous as the others. For some reason, though, I can't get the Coronado series to survive even the summer, let alone overwinter.
I'll have to take pictures of my Acapulcos.. my back yard looks pretty nice with all of them everywhere & the hummers are loving it!!
