One of the new plants in the garden this year that has really thrilled me is heucherella 'Redstone Falls.' I got three of these through the Yahoo Co-op as plugs and they are all over a foot wide now. The coloring in their part-sun location is a gorgeous combination of terra-cotta, orange, yellow, green and a hint of red.
I'm really loving all of the new heucheras and heucherellas that are being developed (many by Terranova Nurseries), but you do have to be a bit careful as to placement of them. I've found that many prefer a good amount of sun, although others tolerate—no, demand—shade. Clearly I hit the nail on the head with where Redstone Falls ended up.
