Description and Ethnobotany
| Growth Form | Woody shrub with an erect growth habit up to 0.9 m tall. |
|---|---|
| Foliage | Smooth, green leaves are narrowly oblong with toothless leaf margin. |
| Stems | The grey, woody stem is densely lined with brownish, conical spines which are long and stiff. |
| Flowers | The inflorescence, known as a cyathium (plural: cyathia), resembles a single flower. The 2 oval, overlapping, petal-like structures are modified leaves known as bracts. The bracts surround a yellow, tiny cluster of male and female flowers which lack petals. The cyathia are grouped in large, showy clusters that resemble the inflorescence of a Hydrangea. |
| Cultivation | This hybrid is highly drought tolerant and requires well-drained soil. Allow the soil to dry completely before re-watering. Apply a half-strength, balanced fertilizer once or twice a year. |
