Clerodendrum ugandense
"Blue Butterfly Bush"

Reaching 4-5’ in its first year, this fast-growing shrub features an abundance of two-tone blue flowers shaped like little butterflies! Hailing from east Africa, it forms a multi-branching 6-10’ shrub with ovate green leaves that have a mild peppery taste, which may explain why this shrub is largely pest free. It bursts into bloom in late Spring and flowers nearly nonstop till first frost with 1.5” flowers that really do resemble butterflies, with pale blue “wings” above a violet-blue tail, all topped by a curling slender stamen “antennae”. Useful as a screening shrub, focal point, or foundation planting. Regular water promotes lush growth. Hardier than most other species in this tropical genus, it does well in our Bay Area climate. Plant in sun (coast) to light shade (inland) in fertile, well-drained soil. Deer resistant.
