White Lavatera Trimestris is a robust, fast growing, shrubby annual plant native to a Mediterranean region. It is the best to plant white seeds directly outdoors in spring, but the seeds can be started indoors for earlier bloom. Also called Tree Mallow, Annual Mallow, Royal Mallow, and Malva Trimestris, Lavatera Trimestris grows into a fairly tall, freely branching shrub that is covered with numerous, large, up to 4 inches across, satiny, ice-white, pink or rose colored flowers. Rose Mallow grows quickly and blooms heavily for many weeks in summer and fall, attracting bees, butterflies, and hummingbirds.

White Mallow is a popular annual flowering shrub for flower beds, borders, and container planting. Lavatera Trimestris seeds have to be covered slightly with soil, and the established Rose Mallow tolerates a wide range of soil conditions, thriving in full sun but tolerating some partial shade. White Mallow can re-grow following spring if seed falls on bare ground.
