Leaves grow from robust standing leaf stalks. They are shaped like an arrowhead and can be more than eight inches wide. Leaves stand straight and spread out. Flowers are typically about a half inch long with three petals that are mostly white but have a red splotch at the bottom. There is a ring of yellow stamen in the center. Flowers curve inward and cover most of the fruiting head.
