Name: Hibiscus rosa-sinensis 'Big Bang' (Big Bang Tropical Hibiscus)

Average Landscape Size: 4–6 ft. tall × 3–4 ft. wide; upright, shrubby habit.

Sun Requirements: Full sun (at least 6–8 hours) is required for the best bloom production and vibrant flower colors.

Water Needs: High; tropical hibiscus love water but hate "wet feet." In the heat of a Houston summer, plants in containers may need watering daily.

Deer Resistance: Low

Cold Hardiness: USDA Zones 9–11; this is a tropical plant and will not survive a freeze without protection.

Fertilization & Pruning: Feed regularly during the growing season (spring through fall) with a high-potassium fertilizer to encourage continuous blooming. Prune in early spring to shape the plant and encourage fresh wood for new flowers.

Detailed Description: If you want a plant that makes people stop and stare, the Big Bang Tropical Hibiscus is the one. This variety is famous for its "dinner plate" sized blooms that feature a spectacular sunrise of colors—bright yellows and oranges that bleed into a deep, velvety red throat. Its dark green, glossy foliage provides the perfect backdrop for these massive, ruffled flowers, making it a favorite for poolside planting or as a focal point in decorative patio pots.

Because we live in the Houston metro area, we have the perfect humidity and heat to make these plants thrive all summer long. While each individual flower typically only lasts one or two days, a healthy Big Bang Hibiscus is a bloom machine, constantly producing new buds from late spring all the way until the first frost. It’s a heavy feeder, so keep it well-fertilized and well-watered, and it will reward you with a tropical light show for months on end.
