Euphorbia degeneri, commonly known as Akoko, Degener’s Spurge, or Beach Sandmat, is an evergreen shrub native to the Hawaiian Islands. It thrives in a variety of habitats including dry forests, subalpine shrublands, and occasionally in coastal areas, but more typically away from the immediate shoreline. It can reach a height of 1-3 feet (0.3-0.9 meters) and a similar width, with a compact and branching growth habit.

Euphorbia degeneri is valued for its drought tolerance and its ability to thrive in challenging environments, making it a suitable choice for xeriscaping and rock gardens. It features small, inconspicuous flowers surrounded by colorful bracts that can range from yellow to red, adding a subtle interest to the garden. The plant is also culturally significant in Hawaii, where it is used in traditional lei making. In cultivation, it requires minimal care, thriving in full sun to part shade and preferring well-draining sandy or loamy soils. It is drought-tolerant once established, requiring only low amounts of water. Gardeners should handle this plant with care, as the sap can be irritating to the skin and toxic if ingested.CC BY-SA 4.0
