Campsis radicans 'Flamenco' (Trumpet Vine 'Flamenco') is a vigorous woody vine prized for clusters of red trumpet-shaped flowers with orange throats that open through summer on new growth. You can use it to cover a sturdy arbor, pergola, fence, pole, or other strong support where you want bold color and a dramatic vertical accent.
Give your plant full sun to partial shade. You will get the heaviest flowering with more sun, while light shade is tolerated. The tubular blooms are an excellent nectar source and are especially attractive to hummingbirds, and the vine can also draw other garden wildlife activity during the bloom season.
This selection can reach 360-480 inches tall, so plan ahead with a permanent structure and space. Train young stems as they grow, then prune in late winter or early spring to manage size and to encourage strong new shoots, since flowering occurs on current season growth. It clings by aerial rootlets, so place it where you want it to attach and climb.
It adapts to many soils and can handle periods of dryness once established, but it performs best with regular moisture while it is getting rooted in. Keep mulch off the stems, water deeply during extended dry spells, and avoid overly rich soil if you want more flowers and less rampant leafy growth.
Because trumpet vine can spread and send up shoots, choose a site where you can monitor it and keep unwanted growth removed. Wear gloves if you are sensitive, as sap may irritate skin. With thoughtful placement and routine pruning, 'Flamenco' rewards you with a long season of showy, hummingbird-friendly blooms.
