A woody sub shrub growing 7-8 feet (2-1.5m) tall, acting as an annual or perennial.This variety typically blooms in the following colours: Crimson and Pale pink and Antique white. The mature flowers are of a single form. The leaves of this particular variety normally show as Islamic green and OU Crimson Red colour. Roselle grows as an annual and is a flowering edible legume / flower. Being an annual plant, it tends to grow best over the course of a single year. Normally reaching to a mature height of 6.50 feet (2.00 metres). This plant tends to bloom in mid autumn, followed by first harvests in late autumn.
South Africa is believed to be where Roselle originates from.

Irrigation: Mature plants are highly drought resistant but may
require water during dry periods when soil moisture is depleted to the point
where wilting occurs.
Nutrition: A side dressing of NPK and dolomite before planting will
promote early growth on soils that are marginally fertile, otherwise fertiliser
is rarely necessary unless the soil is completely deficient in nutrients.
Harvest: The inflated and ripened outer fleshy casings (calyces) should be
ready for harvest 20 days after flowering. The inside seedpod should be still
green when fruit is picked, although fruit can remain on the plant until the
pods mature and seeds disperse. A yield of 1.5 kg of calyces per plant can
be obtained (approx 8 t/ha). Young shoots and leaves can be eaten raw or
cooked as a vegetable and are harvested when required. Yield for leaves,
is about 10 t/ha.
Post Harvest: Store fresh at 7-10?C at a humidity of 90–95%.
Plant in a location that enjoys artificial lighting / artificial lighting and remember to water very often. Zone 1 to 14 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Roselle requires a chalky, loamy or peat-rich soil with a ph of 7.6 - 9.0 - it grows best in weakly alkaline soil. Keep in mind when planting that Roselle is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.
Pests and Diseases: Root-knot nematodes, caterpillars, leaf spot
(Cercospora sp), and black spot.
Ground Preparation: Soil should be deep ripped and formed into
A green manure crop grown and turned in before planting is
Seed can be broadcast onto beds and thinned to 60–80 cm apart or
as seedlings and transplanted into rows 80–100 cm apart. Seeds should be planted during the early wet season as rosella is a
short day-length plant and requires 12–12 ½ hours of daylight to flower.
Nowadays the red calyx is commonly used in jams and cordials
Flowers are edible and the petals and leaves can be used fresh salads, the tender young leaves may be cooked as spinach 1
Let the calyces dry and pick when the interior seed pod has opened. Seed Viability is two to three years.

These problems, diseases and pests are known to affect Roselle plants:
Susceptible to root knot nematodes, therefore, do not plant in the same place every year.
Traditionally, shoots, leaves and roots were eaten without preparation, flowers were eaten raw or cooked and the fibre was used to make dilly bags and hunting nets. 1
