Rotheca myricoides syn. Clerodendrum ugandense, Blue Butterfly Bush

Rotheca myricoides syn. Clerodendrum ugandense
 Blue Butterfly Bush

The porcelain blue flowers of this 2.5 metre shrub need to be seen up close to admire the detail of its mimicry of a blue butterfly. This Uganda native flowers for most of the year and is still producing open sprays at the end of branches. It is not a fantastic looking shrub, being open and twiggy so it needs a solid dark green background or wall to set off the flowers. In really cold weather or in frosty areas, it may become deciduous but recovers quickly once the warm days return.
