Rhodochiton atrosanguineus AGM
This is a fascinating tender climber from Mexico, the Purple bell vine, bears long dangling flowers resembling drop earrings, from midsummer to autumn. Each flower is composed of a long, slender, purple-black tube growing out of a chalice-shaped mauve calyx. The plants are useful for covering trellis or arches, or adding interest to the bare base of other climbers. is NOT hardy but it is so stunning I make exception and keep it in the greenhouse over the winter. You could grow it in a conservatory or porch instead and you should have flowers for most of the year. Ht 60cm. Do not overwater!
