Here I am offering a pint plant of Thunbergia alata Raspberry Smoothie, also known as Black Eyed Susan Vine. Definitely put this plant in a spot where it can get full sun. Raspberry Smoothie grows 6 or even 8 feet long at times and can be grown in a container in case you need to give it some winter protection. This beautiful perennial vine is a big hit with the birds, bees, and butterflies. USDA Hardiness Zones 8 to 11
