It was first described in 1753 by Carl Linnaeus as Lavatera arborea,[4][5] but was transferred to the genus, Malva, in 1836 by Philip Barker-Webb and Sabin Berthelot.

Its level of salinity tolerance is thought to be improved by soil with higher phosphate content, making guano enrichment particularly beneficial.

[1][3][11][12][13] The leaves of the species are used in herbal medicine to treat sprains, by steeping them in hot water and applying the poultice to the affected area.

[19][20] Tree mallow seeds may be transported between separated coastal areas by the floating fruit, and seabirds are considered a likely means of spread.

[9] The tree mallow's recent increased range among Scottish islands has raised concerns that it is displacing native vegetation, and is reducing Atlantic puffin (Fratercula arctica) populations in affected areas.
