Description

‘Red Star' is a cultivar of white cypress. It is a woody, needled evergreen tree or shrub in the Cupressaceae (cypress) family.  The parent plant is native to the wetlands and bogs of eastern United States. This cultivar was first discovered in the 1960s in Winchester, Tennessee by Humphrey J. Welch at the Tennessee Valley Nursery and it is known for its colorful needles that provide year round interest by changing from silvery blue in the spring to deep green blue in the summer and purple-bronze in the winter.  The genus name derives from the Greek word chamai, for dwarf or low to the ground, and kyparissos, for cypress.

It requires full sun to partial shade, loam or sandy moist soil with a neutral to acidic pH and good drainage, though the plant tolerates wet soils where other evergreen plants suffer. The best winter color will appear in full sun.

It is a dense, columnar small tree or shrub with silver to blue-green foliage during the warm season that turns a deep reddish-purple in the cold season. Cone clusters provide winter interest. It may take 10 years to fully mature to 15 to 25 feet tall and 4 to 12 feet wide. 

‘Red Star’ is an easy to grow low maintenance plant for coastal gardens. Plant a specimen in a container, lawn, or near a pond. It is also conducive to mass planting or planting in small groups. Add it to rain, rock, or winter gardens. It is deer resistant. 

Insects, Diseases, and Other Plant Problems: No serious problems.
