Cassia bicapsularis: Butterfly Bush
While other trees are preparing for winter, butterfly bush is just waking up. This sprawling, semi-evergreen shrub, reaching a height of 8 to 10 feet with an equal spread, produces blossoms in fall that resemble golden butterflies. Bright yellow flowers appear at a time of year when little else is in bloom. This plant has a place in any sunny landscape.
