How to Grow and Care
It is a coastal xerophyte, growing in extremely arid to arid areas of several islands, typically on more or less compacted dunes close to the sea but also in coastal cliffs and stony coastal plains. It is also found in sub-humid to humid mountain areas. In the Canary Islands, it forms psammophyte communities with Convolvulus caput-medusae and Heliotropium bacciferum ssp. erosum, Zygophyllum fontanesii, and Euphorbia paralias.
It is a low-growing, grey hairy plant seldom seen in cultivation. However, it has been used extensively and successfully in sand-binding experiments on dunes.
