Plant Bio

Roselle, also known as Hibiscus sabdariffa, is a species of flowering plant in the family Malvaceae. It is native to West Africa and Southeast Asia but is now widely cultivated in many tropical and subtropical regions around the world for its edible calyces and medicinal properties.

The Roselle plant can grow up to 2.5 meters tall and has lobed leaves that are green in color. The flowers of the plant are typically yellow with a red center, and they bloom from mid-summer to early fall. The calyces, which are the fleshy, cup-shaped structures that surround the base of the flower, are harvested for their culinary and medicinal uses.

Roselle is commonly used to make a tart and refreshing drink called hibiscus tea or sorrel. The calyces are boiled in water and then sweetened with sugar to make this popular beverage. In addition to its culinary uses, Roselle has been used for centuries in traditional medicine to treat a variety of ailments such as high blood pressure, liver disease, and fever.

Roselle (Hibiscus sabdariffa) is a tropical plant that is primarily cultivated for its edible calyces, which are used to make beverages, jams, and jellies. It is also known as Rosella, Red Sorrel, or Jamaican Sorrel. Here is a description and care guide for Roselle:

Description:

Growth habit: Roselle is an annual or perennial plant, depending on the climate. In tropical regions, it can grow as a perennial shrub, reaching heights of 6 to 8 feet (1.8 to 2.4 meters). In colder climates, it is typically grown as an annual and may reach heights of 3 to 6 feet (0.9 to 1.8 meters).
Leaves: The leaves of Roselle are deep green and have a lobed or serrated edge. They are usually about 3 to 6 inches (7.6 to 15.2 cm) long and alternate along the stems.
Flowers: The flowers of Roselle are large and showy, with petals that can be white or pale yellow in color. However, the main attraction of the plant is the calyx, which surrounds the flower and is harvested for its culinary uses. The calyx is typically deep red and fleshy, resembling a fruit.
Harvest: The calyces of Roselle are harvested when they are fully grown and have a bright red color. They are usually harvested before the seeds develop inside.

Care:

Sunlight: Roselle thrives in full sun. It requires at least 6 to 8 hours of direct sunlight daily to grow and produce abundant calyces.

Temperature: Roselle is a warm-season plant and prefers temperatures between 70°F and 95°F (21°C to 35°C). It is not frost-tolerant and should be protected from cold temperatures. If grown as an annual in colder regions, plant it after the last frost date.

Soil: Plant Roselle in well-draining soil that is rich in organic matter. The soil should have a slightly acidic to neutral pH level, ideally between 6.0 and 7.5.

Watering: Roselle requires regular watering to keep the soil consistently moist. Water deeply when the top inch (2.5 cm) of soil feels dry, but avoid waterlogging. Ensure proper drainage to prevent root rot.

Fertilizer: Roselle benefits from regular feeding. Apply a balanced fertilizer or organic compost before planting, and supplement with additional fertilizer every 4 to 6 weeks during the growing season. Follow the package instructions for application rates.

Pruning: Pruning is not necessary for Roselle, but you can pinch back the tips of the plants when they are young to encourage bushier growth. Remove any dead or diseased branches as needed.

Pests and diseases: Roselle is generally resistant to pests and diseases. However, aphids, whiteflies, and spider mites may occasionally infest the plant. Regularly inspect the plant for any signs of pest damage and treat with appropriate organic insecticides if necessary.

Harvesting: Harvest the calyces of Roselle when they are fully grown and have a bright red color. Simply cut the calyces from the plant using clean, sharp scissors or pruning shears. The calyces can be used immediately or dried for future use.

Roselle is a versatile plant that not only adds beauty to the garden with its showy flowers but also provides delicious and nutritious calyces for culinary purposes. With proper care, including full sun exposure, well-draining soil, regular watering, and occasional feeding, you can enjoy the benefits of growing Roselle in your garden.
