The natural variance of leaf form has been exploited in the selection of plants for the market. Broader and lobate leaves of some Alyogyne cultivars may have been hybridized with Alyogyne huegelii. The former name of Hibiscus hakeifolia and other synonyms are still given in some sources.
These leaves have 5 to 7 basal veins. Petioles are a gray/green color and range from 0.5 to 1 inch long. Stipules are 1 cm long. [1] [3] Foliage is generally thick and soft to the touch.
