Somewhere between blue and green with yellow details - analogous? They seem to be happy with each other. So is the reddish-brown then complementary? It does seem OK?
I like the stripiness of it (if that is even a word!). It's like a Summer candy cane and looks edible. Russet in the background is nice, as is the black.
@casablanca So well spotted - they are like candy cane stripes - especially the buds. Unfortunately they are really tiny - and stuck on the end of a stupid long stem ( about 2 foot long!) - so they are not very inspiring in the garden. :)
