Have you ever seen a Black-Eyed Susan Vine? Thunbergia alata. Well here is her very swarthy and seductive cousin Thunbergia erecta, all the way from tropical western Africa, commonly known as King's Mantle. The King here brings us a posture a bit different from other twining vine species of Thunbergia. He stands somewhat rigid and tall as a shrub; sometimes twining.
As he stands, he delivers a potent punch of rich, velvety blue flowers with glowing orange throats that provide the perfect pad for prospective pollinators. This shrub can grow up to 6 feet tall and wide. It is replete with deep green leaves and would make an exotically hip hedge in a warm climate. It doesn't mind a good pruning and better yet it blooms on old growth so you're less likely to prune off any flowers. If grown in a cool climate enjoy it as an annual. Let it get full sun, regular water, and situate it in fertile, well-drained soil. Thinking about adding an arousing aura of velvet blue to your world? Look here.
