While valuable in the butterfly garden due to its heat and drought tolerance, Heartleaf Hibiscus has magnificent flowers ranging from two to three inches in diameter. The flowering period is long, from spring through fall but is dependent on rainfall.

Flowers and fruits of the Heartleaf Hibiscus serve as caterpillar food for the Yojoa Scrub-Hairstreak, Mallow Scrub-Hairstreak and Gray Hairstreak.

Heartleaf Hibiscus is an excellent long-blooming nectar source for butterflies.
