Staehelina dubia is a drought-tolerant Mediterranean subshrub that thrives in rocky, poor soils with good drainage and plenty of sun. It requires very little water once established and is well suited to xeriscaping and coastal Mediterranean-style gardens. Its feathery pink-purple flowers are attractive to pollinators and add a delicate texture to dry garden borders.
