Where I work, we carry 18 different cultivars and species of Cercis. There are ones with white variegation ('Silver Cloud'), chartreuse foliage ('Hearts of Gold'), of course purple foliage ('Forest Pansy'), really small leaves ('Ace of Hearts'), weeping branches ('Covey' & 'Traveller'), near red blooms ('Appalachian Red'), double-form blooms ('Flame') and pale pink blooms ('Pauline Lily') not to mention a Chain-flowered Redbud (C. racemosa), a dwarf form ('Little Woody') and a seedless variety ('Don Egoff'). There is no such thing as a boring redbud.
My favorite (pictured below at the J.C. Raulston Arboretum) is Cercis canadensis subsp. texensis 'Traveller'. The growth habit alone provides year-round interest, the blooms are a rich shade of pinky-purple and the foliage is glossy with gently rippled margins. What's not to love?
I planted 2 Redbuds in memory of my parents when they died. I planted them close together, one a year ahead of the other. 0ne tree forms seedpods, the other not. They bloom at different times, and I can see them from several rooms in my house. I've seen the cardinals eating the nutty little center of the bloom, and my bees are fond of them, as well. A beautiful little tree.
