A vigorous Mediterranean shrub with soft, gray-green foliage and abundant pink or lavender mallow flowers throughout warm months. Excellent for coastal gardens and drought-tolerant landscapes.

Why grow it

Tree mallow offers reliable summer flowering and drought tolerance once established, making it a lower-maintenance alternative to many ornamental shrubs in Mediterranean and coastal climates. Compared to hybrid mallows, it tolerates poor soils and salt spray better, though it flowers somewhat later in the season and requires more aggressive pruning to maintain compact form.

Watch out for

This plant responds well to hard pruning in spring but can become leggy if left unpruned for several years. In humid or poorly draining conditions, it is prone to root rot and fungal issues, so ensure sharp drainage and good air circulation around the plant.
