Cassia bicapsularis 'Buttercream' prophouse-on-the-horizon a filler in a shaded'Buttercream' is a pale yellow flowered form of Cassia bicapsularis, a softer, more refined take on that shrub's late season show. Where the species blazes a saturated gold, 'Buttercream' carries clusters of cool, buttery cream yellow flowers through autumn and into early winter, the same butterfly like blooms at the ends of fast, arching branches, and the same draw for Cloudless Sulphur and Sleepy Orange butterflies that feed and breed on the plant.
