Thryallis, Rain-of-Gold

Galphimia glauca

This large evergreen shrub can reach a height of 5 to 9 feet and a spread of 4 to 6 feet. It prefers a slightly acid to slightly alkaline soil pH, 6.0 to 7.2. Any soil texture works well, from clay loam to sandy loam, from sand to sandy clay. Soil moisture should be well drained. Thryallis has medium drought and low to no salt tolerance. It prefers full sun and sports yellow, year-round flowers. Although it is susceptible to caterpillars and mites, we have not experienced those pests here at the Extension office, nor have I at home. This is a great shrub for mass plantings, screening or as a hedge. You can propagate it from cuttings or seeds.

The Bette S. Walker Discovery Garden is one of several demonstration gardens at the UF/IFAS Hillsborough County Extension Service, 5339 County Road 579, Seffner.
