One of the most iconic tropical flowers is that of the Hibiscus. These large red flowers do dissapoint! Hibiscus coccineus is a fast growing Hibiscus native to Florida and has leaves that resemble cannabis leaves. It loves to have wet roots as it naturally grows in swampy areas. It will quickly form a leggy shrub and grows as a perennial in the right conditions. Give it a warm sunny spot with plenty of moisture and a winter mulch to protect the roots.
