Clytostoma callistegioides (Violet Trumpet Vine) is a perennial vine native to South America. It can easily reach heights of 15-20 feet, making it an excellent choice for covering trellises, walls, or even large fences. Once established, this vine will grow quickly, and soon you will be rewarded with its spectacular display of colorful blossoms. Violet Trumpet Vine requires full sun in order to flower and grow, but it also enjoys a bit of shade, especially during the hottest times of the day. It should be kept moist, and will benefit from regular watering and fertilizing during the growing season.
Violet Trumpet Vine produces stunning pink, white, off-white, blue, and lavender-colored flowers that bloom in the spring. These flowers will remain on the plant for four to six weeks attracting both butterflies and hummingbirds. It can be grown in USDA Zones 9-11. When mature, the Violet Trumpet Vine can tolerate temperatures down to 30°F for a short time, making it a great choice for seaside and salt-tolerant plants.
If you live in a cold region, the best way to keep your Violet Trumpet Vine healthy is to grow it in a pot, as this allows you to move it indoors during colder months. Keep the pot in a sunny location, provide regular water and proper fertilization, and you can enjoy its impressive display for many years to come.
