Last year I bought two Hollyhock plants at our local Farmer's Market. They do not blossom the first year, but they grew and made it through the winter and this Spring they really started growing, and getting buds on them. They blossomed starting last week and I am very pleased with the colors. The (almost) black ones are a deep Merlot Wine color. And the light ones are a (almost white) light pink with maroon centers.
Also, my husband picked out a different-looking Geranium with bright pink petals with maroon centers.
I had difficult keeping my hands off the wet watercolor border :-) Just klutzy, I guess!
