Colpoon compressum (Cape sumach) is a hardy, 1–5 meter tall shrub or small tree, endemic to the Cape Floristic Region of South Africa. It is a hemiparasite that photosynthesizes but also taps into host roots for nutrients. Known for its leathery, bluish-green leaves and edible red-to-black berries, it is ideal for coastal, wind-resistant hedging and attracts birds and butterflies.
