Purple Hibiscus is both an annual and perennial herbaceous plant growing into small trees or woody shrubs. The plant is renowned for its showy flowers, which are large trumpet-shaped petals in groups of five or more. It’s also known as the tropical hibiscus and the Fischer's double tropical hibiscus. It comes from the Malvaceae family of plants. Rosa-sinensis means rose of China, where it has been cultivated for centuries and the region where it originated. The purple hibiscus is a tropical perennial shrub.
In the early summer and early fall expect to see the shrub in full bloom. Only leafy dark green foliage remains in the late fall and winter. This plant grows very fast and can be grown in containers, near garden ponds, in outdoor living areas, as landscape borders, and in perennial gardens. Its optimal growing zones are from zone 9a to 10b, tropical and subtropical regions. The Hibiscus is a national flower for many countries, Haiti, South Korea, Malaysia, and the Solomon Islands.
It prefers six hours per day in the full sun or mostly sunny areas with well-drained loamy, sandy or silty soil. The soil's pH should be 6-8. It’s very resistant to heat. The purple hibiscus grows to 5 to 6 feet high with a width of 4 to 6 feet. In the wild, they grow up to 32 feet. The shrub grows fast, needs the average amount of watering and when planted in a landscape will draw butterflies, hummingbirds, and song birds to your garden.
To propagate the purple hibiscus, the gardener can plant its seeds, use grafting, cuttings, tissue culture and air-layering. The hibiscus blooms from late June to early August through to the first frost. To maintain a healthy looking plant, thin out the plant regularly. It can't thrive when the foliage is too dense.
