Botanical Name

CLERODENDRUM splendens

Plant Common Name

Flaming Glorybower

General Description

Crinkly, deeply veined leaves create a lovely backdrop to the festive orange flowers that grace flaming glorybower. This tropical, twining, sprawling evergreen is a native of western Africa, from Senegal to Angola. Its deeply veined leaves are bright green when they emerge and then deepen to glossy dark green. The blooms can appear anytime of year but the heaviest showing of blossoms is in midwinter, just after the solstice.

The flowers heavily cover the twining stems and are borne in big flattened clusters. They are tubular, five-petaled, orange-red and surrounded by purple-red calyces (the leaves that once covered the flower buds). If spent clusters are cut off they will rebloom, but this is at the expense of enjoying the showy fruits that follow. These blue berry-like fruits are supported by the star-shaped calyces and stay pretty for a long time. Hummingbirds love this vine’s flowers as do butterflies.

Grow flaming glorybower in full sun to partial shade and fertile, moisture retentive, acid to neutral soil. It is a shorter vigorous vine that’s perfect for trellises, small courtyard arbors or posts that it can clamber up. It is equally lovely as a billowing groundcover. This vine can survive in areas with occasional light winter frosts, though it will die back to the roots and re-sprout in spring, much like an herbaceous perennial.
