If we're counting only 'outdoor' plants, heuchera is one of the few shade plants I currently have! I love my heuchera and I agree that the foliage on heucheras is among the most diverse of any plant type out there. The name 'caramel', however, is just as attractive to me as the plant itself. (And my husband and I always tease each other about the pronunciation...I'm always chiding him that there's another 'a' in there for a reason!: "car-a
-mel"....but in theory, the "car-mel" does sound more like you have a mouthful of sticky, chewy, yummy caramel in it.
Still, I enjoy our little back-and-forth each time the subject comes up.)
