    Nursery contributed plant descriptions

    Tall spikes of dark golden yellow 1" blooms are born in summer and fall on an upright growing shrub. Called Popcorn Cassia because when brushed or crushed the foliage emits the wonderful fragrance of freshly buttered popcorn. Considered by some to be root hardy in zone 9 with protection.

    Fast growing, gorgeous foliage, luscious black buds & showy bright yellow flowers make this native legume of east Africa a valuable garden accent. To 8’ tall, multi-branching with beautiful tropical looking, bright green, pinnate foliage, this unusual Cassia blooms Spring through Fall but most heavily in Summer & Fall. The showy 2” flowers are densely held on branching spikes up to 1’ long & emerge from rich, shiny black buds. Can get rangy, so prune back after flowering to maintain a pleasing shape or can be trained as an interesting vine subject. Foliage has a rich buttered popcorn scent! May have weed potential, so don’t plant near wild area.
