The Story
Plant Bio
Hibiscus rosa-sinensis, tropical hibiscus, is an erect broadleaf evergreen shrub of Asian origin, four to ten feet high and five to eight feet across. Glossy dark green lobed leaves with toothed margins and clear palmate veining clothe the frame, and funnel-shaped flowers three to six inches wide open from spring through autumn.
Each flower lasts a single day, which sounds like a flaw until you see how many a settled plant opens in succession from spring to autumn. It flowers on new growth, so pruning drives the display rather than costing it. NCSU records it supporting the specialist bee Ptilothrix bombiformis alongside hummingbirds and butterflies.

Common Questions
Tropical Hibiscus questions
What zones can Tropical Hibiscus grow in?
Tropical Hibiscus is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Tropical Hibiscus deer resistant?
Not reliably. Deer may browse Tropical Hibiscus, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Tropical Hibiscus bloom?
Tropical Hibiscus typically blooms in spring to fall through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Tropical Hibiscus need full sun?
Tropical Hibiscus does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
