Black Eyed Susan Vine Seeds


Sold out for 2024

Thunbergia alata

Masses of blooms all summer and large, lush foliage that looks very full and bushy but never gets out of hand. Ideal for growing up through fences and gates, or up and over your mailbox. Works well in containers with a small trellis too, where its full habit makes an impressive display. The cheerful 1-2” blooms are prolific and visited by hummingbirds, bees, and butterflies alike. Petal colors range from bright-yellow to deep orange, with some, but not all of the blooms featuring the characteristic black eye.
