Genus Lavatera, also known as tree mallows, is a group of flowering plants that are admired for their attractive blooms and foliage. There are several synonyms for this genus, which are often used interchangeably. These include Althaea, Kitaibelia, Malvastrum, Malva, and Sphaeralcea. Althaea, another of the synonyms for Genus Lavatera, is derived from the Greek word 'altho,' which means 'to heal.' This is due to the medicinal properties that were attributed to some species of this genus. Malva and Malvastrum are derived from the Latin word 'malva,' which means 'mallow.' This is because the appearance of the flower is similar to the common mallow plant.
