Double Red is a classic tropical hibiscus known for its rich, velvety red flowers and continuous bloom. Each blossom is fully double, made up of many overlapping petals that form a lush, ruffled bloom about 4 inches across. The deep red color stays consistent even in full sun, creating a striking display against the glossy green foliage.
This variety is one of the most dependable and easy-to-grow tropical hibiscus types. It flowers freely through the warm months and can bloom almost year-round in frost-free climates. Like most hibiscus, each individual bloom lasts only a day, but new buds open daily, keeping the shrub in near-constant color.
Double Red grows into a dense, rounded shrub about 4-6 ft tall and 3-4 ft wide. It's ideal for hedges, accents, or large containers on patios and pool decks. Plants perform best in full sun with regular watering and rich, well-drained soil. Feed monthly during the growing season to encourage continuous flowering.
This time-tested hibiscus is a true garden classic, combining vivid color, strong growth, and reliable performance. Its full, double blooms and intense red tone make it one of the most popular hibiscus varieties ever introduced.
In TopTropicals garden this variety showed pretty strong cold tolerance (at least to light freeze) similar to cold hardy H. syriacus. It is often referred to as H. Althea, H. Amplissimus (referring to double flower), and Double Rose of Sharon. This variety is also known under names: Red Hot, President, Red Dragon, Super Red.
