Stand beneath this fast-growing beauty, and you’ll feel its bold, seaside presence. Tree Mallow, also known as Tree Mallow, is a robust, shrubby plant that forms a striking, upright specimen with a single stout stem that becomes woody at the base, reaching up to 3 metres tall. Large, rounded, palmately lobed leaves up to 20 cm across are densely covered in soft hairs, giving them a distinctive velvety, felted texture and grey-green appearance. From late spring through summer (and often into autumn), it produces an abundance of showy, funnel-shaped flowers in deep pink to purple-pink, each with prominent darker purple-red veins radiating from the centre—a striking pinwheel effect.
Native to the coastal regions of western Europe and the Mediterranean, Tree Mallow has proven wonderfully suited to the Western Cape’s temperate, coastal climate. It thrives in full sun to partial shade and is remarkably tolerant of strong, salt-laden coastal winds, making it invaluable for seaside gardens. It prefers well-drained, sandy or loamy soils and, once established, is moderately drought-tolerant. It’s hardy to light frost but best suited to mild, frost-free coastal areas. Reaching 1.5–3m tall and 1–2m wide, it’s perfect for coastal gardens, mixed borders, or as a dramatic flowering accent in a large container.
Key Features:
- Large, funnel-shaped flowers in deep pink to purple-pink with darker veins—a long, showy display
- Exceptionally tolerant of strong coastal winds and salt spray
- Large, rounded, lobed leaves with a distinctive velvety, grey-green texture
- Fast-growing, upright form; nectar-rich blooms attract bees and butterflies
Gardening Note: Plant in full sun to partial shade in well-drained soil—ideal for coastal gardens where it will thrive in salt-laden air. Water regularly until established; mature plants are moderately drought-tolerant. Deadhead spent blooms and pinch back young plants to encourage bushier shape and extend flowering. Can be grown as an annual or biennial, often flowering in its first year from seed; may self-seed in the garden.
