Mexican Turk's Cap (Malvaviscus arboreus var. mexicanus) has almost glabrous leaves with truncate bases; whereas, Turk's Cap (Malvaviscus arboreus var. drummondii) has densely tomentose abaxial leaf surfaces and cordate bases. M. arboreus var. mexicanus has larger flowers (up to 50 mm long) and leaves than M. arboreus var. drummondii (flowers 35 mm long) and is more more "Hibiscus-like" or upright in habit. M. arboreus var. mexicanus blooms usually hang downward; whereas, M. arboreus var. drummondii blooms are more erect. M. arboreus var. drummondii is smaller in stature and has more of a "sprawling" habit. M. arboreus var. mexicanus is less free-flowering than M. arboreus var. drummondii with the heaviest bloom production in late summer through fall. Also, M. arboreus var. mexicanus is a bit less hardy than M. arboreus var. drummondii.
