Products > Distictis 'Rivers'   Distictis 'Rivers' - Royal Trumpet Vine     [2nd Image] Habit and Cultural Information Category: Vine Family: Bignoniaceae (Bignonias) Origin: Mexico (North America) Evergreen: Yes Flower Color: Violet Bloomtime: Spring/Summer Synonyms: [D.'Mrs. Rivers', D. riversii, Amphilophium] Parentage: (Distictis buccinatoria x D. laxiflora) Height: Climbing (Vine) Width: Spreading Exposure: Full Sun Irrigation (H2O Info): Medium Water Needs Winter Hardiness: 20-25° F 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. Showy lavender flowers fade to light lavender throughout the warm months. Plant in full sun to part shade and water occasionally in the summer. It looks a lot like D. laxiflora, but has a slightly more vigorous look about it with slightly larger blooms and leaves. 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. Violet trumpet flowers grow 5 inches long and bloom throughout the warmer months. Plant in full sun to part shade, water occasionally in the summer. This plant of hybrid origin is the result of the cross between two Mexican vines that both were known as species in the genus Distictis but the current genus for both, according to The Plant List, the collaborative authoritative listing by Kew Botanic Garden and Missouri Botanic Garden, is Amphilophium which would likewise make this hybrid a Amphilophium. We will continue to list this plant as Distictis 'Rivers' until such time as this name change has wider acceptance.  The information on this page is based on research conducted about this plant in the San Marcos Growers library, from online sources, and from observations made of the crops growing in our nursery, plants in the nursery's garden and those in other gardens where we may have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Distictis 'Rivers'.     [MORE INFO]
