| Family Name: | Malvaceae |
| Synonyms: | Hibiscus gossypiifolius, Abelmoschus cruentus, Hibiscus digitatus, Sabdariffa rubra, Hibiscus sanguineus |
| Common Name: | Roselle, Jamaica Sorrel, Red Sorrel, Sorrel, Indian Sorrel, Asam Susar, 玫瑰茄, 山茄子 |
Roselle (Hibiscus sabdariffa) is a popular relative of the Lady's Finger, where its fleshy red calyces are commonly used in making jams and beverages with blackcurrant-like taste. Easily grown from stem cuttings or seeds, this sun-loving shrub can be planted on the ground or in containers where it receives at least 6 hours of sunlight daily. This plant has ornamental pinkish flowers and trilobed leaves making it an excellent hedge or border plant.

Description and Ethnobotany
| Growth Form | Woody, perennial shrub with an erect form, able to grow up to 1 - 2 m tall. |
|---|---|
| Foliage | Dark green leaves are either lanceolate (3 - 7 cm wide, 11 - 16 cm long) or tri-lobed (19 - 20 cm wide, 15 - 16 cm long) with serrate leaf margins. Tri-lobed leaves are deeply lobed. The same individual may produce both leaf types. |
| Stems | The stem is woody and red to purple. |
| Flowers | Pinkish flowers (8 cm wide) have a red spot in the center, bright red, fleshy calyx enclosing the base of the flower. |
| Fruits | Dehiscent, dry fruit is classified as a capsule. It releases many brown, bean-shaped and wrinkled seeds (0.6 cm wide). |
| Cultivation | Plant this species in well-drained, slightly acidic soil (pH = 5 - 6.5) that is rich in organic matter and moisture retentive. Flowering occurs 45 - 60 days from seed planting. Calyces are ready for harvest about 35 days after flower opening. Prune the shrub to promote branching. Hard pruning will encourage the formation of larger flowers. This species is susceptible to root knot nematodes (Meloidogyne spp.). Mulching the plant and re-planting from seed in new areas will help to control the nematode population. Other problems include bacterial diseases caused by Xanthomonas campestris pv. malvacearum and Pseudomonas cihorii. These diseases can be controlled by keeping the foliage dry and spraying with chemicals such as mancozeb or copper sulfate pentahydrate. Plants are also prone to attack by whiteflies and two-spotted mites which can be sprayed with insecticidal soaps and horticultural oils. Stem and root rot can be a serious problem. |
| Etymology | Genus Hibiscus is from the Greek word hibiskos which Roman poet Virgil used to relate to the marsh mallow plant. Species epithet sabdariffa is the name of a genus that this species was once placed in. The common name "Roselle" is likely a corrupted version of the French name for this plant, "Oseille de Guinée," which means Guinea Sorrel. |
| Ethnobotanical Uses | Edible Plant Parts (Edible Flowers, Edible Leaves) Food (Fruit & Vegetable : The young shoots have a sour taste. They can be consumed raw or cooked and may be added to salads, soups and meat or vegetable dishes. Fresh or dried calyces can be immersed in hot water and then sweetened with sugar to prepare a beverage that is rich in antioxidants, such as Vitamin C and anthocyanins. Its taste is similar to Ribena (a blackcurrant-flavored drink). In the Caribbeans, people drink the juice extracted from the calyces either fresh or fermented. The versatile calyx is also used as a natural food coloring, as well as for making jams which taste like cranberry sauce.) Medicinal ( Scientific Evidence of Medicinal Properties In both pre-clinical and clinical trials, Roselle showed antioxidant (Usoh et al., 2012; Frank et al., 2012) and cholesterol-lowering properties (Usoh et al., 2012; Hajifaraji et al., 2018) in animals and people, respectively. In pre-clinical trials, Roselle showed pain-relieving (Ali et al., 2013), anti-cancer (Huang et al., 2018), anti-diabetic (Ndarubu et al., 2019), anti-inflammation (Ali et al., 2013), anti-microbial (Portillo-Torres et al., 2022) properties in animals. Traditional Medicinal Uses Research supports the traditional use of Roselle to treat ulcers. It is important to note that some therapeutic effects from traditional medicinal uses of plants are not currently supported or verified by scientific research. )Cut - Dried Flower ( This species produces a large number of attractive, red flower buds. These buds, as well as flowers that have bloomed, could be used as part of a floral arrangement.) |
Landscaping Features
| Landscaping | This species makes as excellent hedge or border plant. The reddish stems and flower buds add colour to the landscape and also provide contrast against the dark green colour of the leaves. The tri-lobed leaves also help to give this shrub a unique appearance. Plant several individuals together to maximize the impact of its colour. |
