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.

Purple Hibiscus are in full bloom early summer and early fall

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.

A closely related member of the Malvaceae family to the purple hibiscus is the “Rose of Sharon” or Hibiscus syriacus. According to legend this deciduous shrub originated in Syria, but now is considered native to East Asia in general. Today, the deciduous Rose of Sharon shrubs are cultivated in a wide variety of geographical regions around the world for their flamboyant blossoms and can grow upright eight to ten feet tall and six to eight feet wide. Flowers of the many-stemmed Rose of Sharon, also known as Althea shrubs, appear from June to September. The blossoms range in color from splashy pink to purple, magenta or violet hues. These shrubs may be pruned to shapes like trees or vases. They do well in hot weather but will survive in USDA Hardiness Zone 5. The precisely calibrated soil is not a critical factor in assuring excellent growth and flowering of althea shrubs. In fact, these shrubs are easily transplanted and can provide aesthetically pleasing garden borders and hedge like backyard screens. In the spring, ensure optimal growth and blossoming by pinching back the stems and leaves that have decreased during the winter.

The majestic royal purple blossoms of this colorful hibiscus variety make for brilliant floral arrangements in combination with canary-yellow orchids or lemon-hued irises. Bouquets including the royal purple variety of hibiscus attractively complement weddings or black-tie events.

Purple Hibiscus 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 songbirds 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.
