Clerodendrum quadriloculare - Fast-growing starburst clerodendrum grows well in zones 9b to 11 and can be used as a shrub or tree. Typically reaching a height of 15 feet, this plant is most eye-catching in mid-winter and early spring when its showy tubular flowers—white-tipped and pink below—appear in large clusters. Hummingbirds and long-tongued butterflies love to visit these tubular flowers for their sweet energizing nectar.

The rest of the year, it’s the foliage that’s the point of interest. The topsides of the leaves are green, with just a tinge of purple, while the undersides are a glossy, deep purple.
