How to Grow Campsis radicans

Overview

Campsis radicans, also known as trumpet vine, is a stunning deciduous woody vine native to eastern North America. With its vibrant flowers and hardy nature, it's a perfect choice for any gardener looking to add a pop of color and a touch of wilderness charm to their outdoor space.

Growing Conditions

Trumpet vines thrive in full sun or partial shade, preferring locations with at least six hours of direct sunlight each day. They are heat and drought tolerant, making them ideal for warmer climates. Campsis radicans prefers well-drained soil rich in organic matter, so be sure to amend your planting site if necessary.

Planting & Care

Plant trumpet vine seeds directly outdoors in the spring after the last frost date, or start indoors 4-6 weeks earlier. Mature vines can grow up to 10 meters long, so provide a sturdy trellis or fence for support. Water regularly during dry spells and apply an organic fertilizer once a month to keep your plant healthy.

Common Problems

The main issue with trumpet vines is their ability to become invasive if not properly contained. If left unchecked, they can spread quickly, overtaking nearby plants and landscapes. Prune regularly and remove any seed pods that develop to maintain control over the vine's growth.

Harvest or Enjoy

Harvesting trumpet vine seeds is easy once your plant has matured. Simply allow the seed pods to dry on the vine before collecting them for propagation. Alternatively, enjoy the vibrant flowers throughout summer and into fall, as they attract pollinators like bees and butterflies to your garden.
