A Non-Rampant Cultivar of the Trumpet Creeper

Making It Grow Radio Minute
SC Public Radio

Many of our native plants have relatives in other parts of the world. Campsis radicans, native to North America has an Asian relative, Campsis grandiflora. Many crosses have been made between the two, with the name of Campsis x tagliabuana which have given us less aggressive plants. Madame Galen is a cultivar that’s frequently offered. But they still make seeds and can spread where you don’t want them. Fortunately, there is a way to grow a Campsis vine that will provide nectar for hummingbirds and butterflies but will not spread other than by root shoots. North Carolina State’s Mountain Crop Improvement Laboratory developed a sterile cultivar, Campsis x tagliabuana ‘Chastity’ which does not produce viable seeds but has the same beautiful deep orange red flowers, and grows well in a variety of situations, just not so rampantly as our native trumpet creeper.

She studied horticulture at Clemson University as a non-traditional student. “I’m so fortunate that my early attempts at getting a degree got side tracked as I’m a lot better at getting dirty in the garden than practicing diplomacy!” McNulty also studied at South Carolina State University and earned a graduate degree in teaching there.
