David, that sounds lovely! I enjoy those autumnal tones, and like mixing those foliage colors among the hotter bloom colors. I find the garden bed that is seen from my deck, is very subdued warm, autumnal tones like that in late spring, being primarily bearded Irises and bronze and gold foliage at that time. In earlier spring it's bright, with lots of Daffodils (and will be extra bright this spring, as I've added lots of Tulips in reds, oranges, and yellows), then the muted tones take over. After that, the Lilies and Daylilies fire things up again.
I just placed my order for Achimines, 5 rhizomes of each.

Karutz was the only company I could find selling them. Brent&Becky's used to offer a couple of varieties, but aren't carrying them this year. Seems I recall they only offered blue/purple/pink selections anyway.
