With many common names (Confederate Vine, Rosa de Montana, Chain of Love), this climber is very popular in the far south and in Mexico where the tuberous roots are eaten for their nut-like flavor. Unlikely to bloom the first year from seed in the north, this makes an excellent greenhouse vine for it blooms best when its roots are confined in a pot. Produces myriads of rose-pink flowers in long trailing sprays all over the surface of the plant. The seeds show its close relationship to buckwheat. Zone 9. Few seeds.
