Appearance
Zenobia plants are deciduous shrubs that can grow up to 6 feet tall and wide. They have a rounded, mounding growth habit and attractive, glossy green foliage that turns red or bronze in the fall. The plants produce clusters of small, bell-shaped flowers in late spring or early summer. The flowers are typically pink or white, and they have a sweet, pleasant fragrance. The flowers are followed by small, dry capsules that contain tiny seeds.
Care Guide
Zenobia plants prefer moist, acidic soil that is well-draining. They should be watered regularly, especially during periods of drought. Fertilize the plants in early spring with a slow-release, acidic fertilizer, and avoid over-fertilization, which can lead to weak growth and susceptibility to pests and diseases. Zenobia plants prefer full sun to partial shade and can tolerate cold temperatures down to USDA Hardiness Zones 5-9.
Common Pests & Diseases
Zenobia plants are generally resistant to pests and diseases, but they can be susceptible to root rot if the soil is too wet. Spider mites and lacebugs may also infest the plants, causing leaf discoloration and damage. To prevent these issues, maintain good soil drainage and regularly inspect the plants for signs of pests and diseases. Remove any affected foliage and treat the plants with an appropriate pesticide or fungicide if necessary.
Habitat
Zenobia plants are native to the southeastern United States and the Appalachian Mountains. They grow in a variety of habitats, including moist woodlands, stream banks, and rocky slopes. The plants are adapted to acidic soils and are commonly found growing in association with other acid-loving plants, such as azaleas and rhododendrons.
