Lavatera thuringiaca is commonly grown as an ornamental plant in gardens and alongside buildings. Due to its height, it is often used as a background plant or to provide a screen or windbreak. It prefers full sun and well-drained soil and is easy to care for, requiring minimal watering and pruning. The plant has also been used in traditional medicine to treat coughs and sore throats, as well as skin irritations and inflammation.

Common Names

In addition to “mallow,” Lavatera thuringiaca is known by several other common names, including royal mallow, tree mallow, and German mallow. In Germany, it is called “Johanniskrautmalve,” which means “St. John’s Wort mallow,” due to its resemblance to the St. John’s Wort plant.

Light Requirements

The Lavatera thuringiaca plant requires full sun exposure of at least 6 hours per day. It thrives in bright light conditions and does not do well in shade. Ensure the plant receives adequate light by planting it in an open area, away from tall trees and buildings that may block sunlight.

Temperature Requirements

The Lavatera thuringiaca can tolerate a wide range of temperatures, but it prefers warm and moderate conditions. It grows best in areas with a temperature range of 60-85? (15-29?). This plant will not survive in areas with frost or sustained temperatures below freezing. During hot weather, provide the plant with frequent watering to prevent wilting, which may occur in very high temperatures.

Soil Requirements

The Lavatera thuringiaca is adaptable to different soil types, though it grows best in well-drained, loamy soils with a pH range of 6-7. The soil should be rich in organic matter, and care should be taken to ensure that the plant is not waterlogged as it may lead to root rot. Before planting, add organic matter to the soil and loosen compacted soil for good drainage. Adequate irrigation is recommended to keep the soil moist.

Cultivation methods

Lavatera thuringiaca, commonly known as rose mallow, is a hardy and easy-to-grow perennial that thrives in full sun and well-draining soil. It also prefers soil with a pH level of 6.0 to 7.0. When planting, dig a hole that is twice as wide and deep as the plant's root ball. Make sure the top of the root ball is level with the surrounding soil and water the plant generously.

Watering needs

Lavatera thuringiaca is a drought-tolerant plant but needs regular watering during the first growing season to establish its roots. The frequency of watering depends on the weather and soil type. Water the plant deeply once per week in the absence of rainfall. It is essential to reduce watering during the winter when the plant is dormant.

Fertilization

To encourage robust growth and blooming, apply a balanced fertilizer during the growing season. A complete fertilizer with an equal ratio of nitrogen, phosphorus, and potassium is ideal. Fertilize every four weeks during the active growth period. Avoid over-fertilizing, which can cause lush foliage at the expense of flowers.

Pruning

Lavatera thuringiaca requires pruning to promote bushy growth and maintain its shape. Prune in late winter or early spring before new growth emerges or immediately after flowering. Cut back the stems to about a third of their length, leaving a few buds on each stem. Deadhead spent flowers to encourage further blooming throughout the growing season.

Propagation of Lavatera Thuringiaca

Lavatera thuringiaca is a beautiful flowering plant that belongs to the mallow family. It is commonly known as the German Lavatera and is popular for its ornamental value.
