As a native of the Madeira Islands off the coast of Portugal, pride of Madeira is naturally adapted to California’s coastal areas. It does well in drier soils, but requires good drainage. It also typically tolerates short cold snaps between 25 and 30 degrees Fahrenheit.
In coastal zones, pride of Madeira typically needs no supplemental water once established. But it may require weekly irrigation during the summer in hot inland areas.
The shrub’s tall upright branches and narrow grey-green foliage make it an excellent background plant in the garden or against a wall. Make sure to give it plenty of room to spread out, since it tends to smother other plants grown in its shadow.
Pride of Madeira also tends to reseed itself. While requiring some additional upkeep, this trait provides free pups to replace this short-lived shrub. Its typical lifespan is about five years.
When pruning or handling this plant, wear protective gloves as its stiff hairs can cause skin irritation. Also use caution around young children and pets, since all parts of the plant are considered toxic if ingested.
