Roselle is a hibiscus species, growing in temperate countries, can grow up to 2–2.5 m (7–8 ft) tall. The flowers are 8–10 cm (3–4 in) in diameter.
In Malaysia it is used as juice, jams & jelly.
The flowers are red in color, and very fleshy once the fruits become mature.
They must be planted in soil, as they will become heavy once starts fruiting and will bend due to weight if the root is not properly fixed in the soil. Once the fruits are matured it is important to collect. If left uncollected, the plant will die.
Once you had collected the fruits, new ones will grow. The plant needs plenty of water.
Roselle is a good antioxidant and is used against atherosclerosis, liver disease, cancer, diabetes and other metabolic syndromes.
I grow my Roselle plants from the seeds.
