While valuable in the butterfly garden due to its heat and drought tolerance, most gardeners will choose heartleaf hibiscus because it has magnificent flowers ranging from two to three inches in diameter. The flowering period is long, from spring through fall in the Lower Rio Grande Valley, but is dependent on rainfall.
Importance as a caterpillar food source: Flowers and fruits of heartleaf hibiscus serve as caterpillar food for the Yojoa Scrub-hairstreak. Eggs of this caterpillar are laid individually on the flowers. Mallow Scrub-Hairstreak and Gray Hairstreak caterpillars also use this plant as a food source.
Importance as a butterfly nectar source: Heartleaf hibiscus is an excellent long blooming nectar source.
