Roselle (hibiscus sabdariffa)
General Info
Roselle, also popularly know as sorrel throughout the Caribbean, is an attractive shrub which produces an edible calyx used in teas, drinks, jams and sauces. The calyx is a fleshy, red cup-like structure which forms after the flower and surrounds the seed pod. Interestingly, a variety which produces white calyces also exists. Roselle is native to west Africa but is grown throughout the tropical and sub-tropical world. The seeds, leaves and roots can also be used in cooking or medicinally.
Size
Up to 7’ tall and can become quite wide as well.
Growing Conditions
Roselle prefers well-drained soil and plenty of sunshine and water, but does not appear to require particularly rich soil.
Years to Fruit
Roselle bushes take 6-8 months to make calyces. Calyces can be harvested in October/November.
Taste
The calyces are tart and reminiscent of cranberry.
Climate
Tropical/sub-tropical.
Cold Tolerance
Roselle plants are annuals and will be killed by cold weather, hopefully after giving a full crop.
