American Cyrilla

Cyrilla racemiflora (sir-RIL-ah rah-see-MIH-flor-ah)

Family: Cyrillaceae Native Understory (15-40 ft)

Swamp titi is an evergreen, semi-evergreen or tardily deciduous shrub or small tree in the Cyrillaceae family that is native to SE North America and occurs in coastal and Piedmont NC. Its preference is for moist to wet well-drained sandy loam high in organic matter in full sun to partial shade. It tolerates drier sites as long as adequate moisture is provided during dry periods. It can form thickets providing cover for wildlife, especially in wet sites. Swamp titi will grow 8- 30 feet tall and spread 10-15 feet wide. It looks shrubby when young but can be trained into a small tree with contorted stems, smooth, cinnamon-colored young bark and flaky mature bark. Showy white clusters of summer flowers and orange-red fall color make this a nice ornamental tree for the home landscape. Plus the pollinators and birds will love you for planting it. Use this tree as a specimen, in a native garden, a pollinator garden or along ponds, streams, bogs, ditches or other wet sites. If you live in hurricane-prone areas, this is a great shrub to plant along the ditches to help prevent flooding. Insects, Diseases, and Other Plant Problems: No significant pests or diseases. Toxic pollen from this plant is responsible for purple brood to honeybee colonies. This plant is not suitable for beekeepers.
