DESCRIPTION
Thryallis (Galphimia glauca) is an evergreen shrub of medium size that produces yellow flowers year round. It thrives in sub-tropical climates, and in the U.S. is becoming more popular for hedging and ornamental use in South Florida. Thryallis grows to about six to nine feet (two to three m.) tall and forms a dense and compact oval shape. It can be used alone or alternated with other shrubs to create a variety of textures, sizes and colors in a hedge.
