Galphimia glauca
As the name implies Shower–Of–Gold offers season–long spikes of bright yellow flowers; flowers are mostly held at or above the dark green to blue–green foliage; with periodic pruning plants develop a dense handsome canopy with enough flowers to draw the eye from a distance.
Exposure: Full sun to very light shade
Size: Height — 3 to 5 feet tall
Plant type: Woody shrub (South Texas) or summer annual (North Texas)
Planting time: Anytime from containers as a shrub, spring as a summer annual
Soil type: Tolerant of most soils as long as they are well drained
Suggested uses: General purpose evergreen shrub in warmer portions of Texas; tolerates summer heat as a patio container; nice background for perennial or annual boarders in South Texas
Special notes: Blooms whenever temperatures permit; annual pruning will maintain a denser habit and plants work well when pruned back as a subshrub or herbaceous perennial
