Distictis 'Rivers' (Royal Trumpet Vine) - This is a fast-growing evergreen vine reaching 30 feet tall and wide. Like the Red Trumpet Vine, one of its parents, it has green somewhat leathery 4-inch-long leaves with tendrils that form disks so it can climb fences and structures. The showy 5-inch-long dark lavender flowers are abundance in summer month flowers and fade to light lavender as they age.

Plant in full sun to part shade and water occasionally in the summer. It is hardy to 20-25 degrees F. When it is well-established, it should regenerate from the roots if it freezes down to the ground. It looks a lot like Vanilla Trumpet Vine, Distictis laxiflora, but is more vigorous larger flowers and leaves and mostly lacking a fragrance.

Distictis 'Rivers' is a hybrid that is the result of the cross between two Mexican vines Distictis buccinatoria and Distictis laxiflora. It has also been called Distictis 'Mrs Rivers' and there is some indication that the plant was named for a Mrs. Lois Rivers, a gardener and plant hybridizer who some credit as creating this hybrid in the 1960s. Both parent plants were at one time in the genus Bignonia before being moved to Distictis but are now considered to be in the genus Amphilophium, which would likewise make this hybrid a Amphilophium cultivar. We will continue to list this plant as Distictis 'Rivers' so not to confuse our staff or customers until such time as this name change has wider acceptance.
