I'm growing several 'C's'. I have Cinnamon Faces but it hasn't bloomed yet and the only photo is one I lifted off the net that was the hybridizer's and I don't have permission to use it. These others are mine.
Coral Crab bloomed and bloomed and bloomed. Very rewarding last season.
Calico Spider seemed happy here. A splashy piece of work that was very consistent.
Cat's Cradle was actively growing when we got hit with the coldest temps of the winter. I covered it, but not well enough I guess. It never seemed to fully recover. I'm hoping the plant will do better this year. It still managed to be nice.
Chesapeake Crablegs was new and the plant seemed to really struggle, but it put up a lot of stalks with bloom. I probably should have removed them. By fall the plant looked strong, so we'll see what happens this summer. If it was that eager to bloom in a weakened state, it should be a nice clump when it's strong.
