Cobaea scandens

Cobaea scandens, commonly known as Cathedral Bells, is a fast-growing, evergreen climber that can grow up to 10 ft tall. This plant has tendrils on its leaves and produces large, bell-shaped purple flowers during the summer months. It is often grown as an annual and is winter hardy in USDA zones 9-11.

For optimal growth, it is recommended to plant Cathedral Bells in a sunny location with a light, rich soil. This plant requires regular watering during the growing season, but the amount of water should be reduced in late summer or fall. Mulching can help retain soil moisture. To control the size and shape of the plant, pruning should be done in late winter.

In areas with cold temperatures, Cathedral Bells can be grown in a pot and placed in a sunny location. It is important to ensure that the soil remains evenly moist as the roots cannot tolerate dry conditions. After winter, the plant should be cut back to encourage new growth.

Cathedral Bells thrive in locations where it will have plenty of support, such as a fence or trellis. Additionally, this plant is attractive to bees, butterflies, and hummingbirds.
