Cassia corymbosa (Flowery Senna)

An easy to grow, low maintainance, multi-trunked shrub or small tree that will be covered from fall to spring with numerous terminal clusters of bright yellow, one inch flowers that attract butterflies. They can also be trained as an espalier against a wall or fence. The leaves will be evergreen down to temperatures in the teens, and the entire plant can take a ways beyond that before freezing. Though they prefer full sun, they can bloom quite nicely in partial shade. They're also deer-resistant!
