Plant Profile: Tree Mallow ( Lavatera martima aka L. bicolor)

Tree mallow is a semi-deciduous shrub probably from the western Mediterranean where it inhabits dry rocky places often along the coast. It is a large loose shrub with an abundance of showy flowers over a long bloom time beginning in spring in warm climates and continuing into summer and fall. Plants bloom continuously in some areas. Each flower is about three inches across and consists of five lavender pink petals each with a dark lavender pink central blotch and veins. The green calyx visible at the base of the pedals adds a subtle accent. The gray-green maple-like leaves are circular in outline with palmate lobes and a covering of dense matted hairs on both sides. The plant grows very rapidly and needs to be tip pruned regularly throughout the growing season to encourage woody growth and avoid floppiness. A regular fertilization program throughout the growing season will help encourage luxurious growth of both leaves and flowers. Plants are relatively short lived and have a life span of about five years.

Tree Mallow

This useful and fast-growing semi-woody evergreen shrub makes a quick-growing long-flowering windbreak. It has gorgeous large tropical-looking flowers of a rich, luscious maroon, with large, flexible bright- green leaves.The flowers are produced over a long period of time, spring through summer. Endemic to the Channel Islands off the coast of Santa Barbara, it grows surprisingly easily and quickly in many other locations, especially along the coast, where it is not bothered a bit by wind and salt-spray. Germinating readily from seed, it can become 5′ tall in a year, topping off at about 8′.

It thrives in sun to light shade and is adaptable as to soil, but it looks better in fairly lean, well-drained areas. Pruning helps it stay manageable, but it’s best in informal gardens and near tidier plants to provide consistent privacy or barriers. Relatively short-lived, it reseeds well on its own, so replacement plants are quickly grown.Deer like it so it usually needs to be on the protected side of the fence.

Easily grown in the home nursery, tree mallow is a good plant to grow from seed with children. The young “peas,” the immature seeds, before they ripen and mature, are delicious eaten raw or cooked.

Habitat Information
Tree mallow is a tall, native, biennial. Because it is killed by severe frost it is rarely found more than 100 m from the sea (although it grows readily as a garden plant) where it finds protection in the mild micro-climate found there. Tree mallow grows best in shallow, nutrient-enriched soils and is particularly associated with sea-bird roosts. It is found around the coast of southern Britain but may have been introduced to many sites and might only be native in the milder west and southwest coasts. Outside of its natural range it can be an invasive and environmentally damaging plant. For this reason it should not be planted in wild coastal sites without first seeking advice from local experts.

The flowers, which bloom throughout June to September, are visited by bees as they offer both nectar and pollen.

Growing Information
Can be sown anytime of the year.
