Nursery contributed plant descriptions

Deep pumpkin orange single flowers with long elegant staminal columns and recurving petals. A rare orange subspecies of the native Hawaiian Kokio Hibiscus, St. John's Hibiscus produces a year round display of 3-4" wide flowers on a moderately vigorous naturally large growing tropical Hibiscus that can easily be maintained as a container specimen where not hardy. Attracts hummingbirds, butterflies, and other pollinators. St. John's Hibiscus has a naturally upright to vase shaped somewhat open habit but can easily be trimmed to keep it fuller and shaped into a denser more shrub-like form as well aa a hedge.
