Summary

Malva arborea, commonly known as Tree Mallow, is an evergreen shrub native to coastal areas and islands of the Mediterranean region and the Atlantic coast, where it often grows in saline environments such as coastal cliffs and salt marshes. It typically reaches a height of 0.5–2 meters, and on rare occasions, it can grow up to 3 meters tall. The plant has a bushy form with orbicular leaves that are 8–18 cm in diameter, palmately lobed with five to nine lobes, and a coarsely serrated margin. Tree Mallow is notable for its showy flowers, which are 3–4 cm in diameter, dark pink to purple, and grow in fasciculate axillary clusters of two to seven. The flowering season extends from early summer to autumn, providing a long-lasting display of color.

Tree Mallow is appreciated for its tolerance of salt spray and its ability to thrive in coastal gardens, making it a suitable choice for seaside plantings. It is also used for ornamental purposes in borders and as a specimen plant. In cultivation, it requires well-drained soils, moderate watering, and can tolerate a range of light conditions from full sun to partial shade. While it is generally easy to maintain, it can be susceptible to rust and other fungal diseases. Gardeners should be aware that Malva arborea can become invasive outside its native range, so it is important to check local regulations before planting.CC BY-SA 4.0
