Roselle is highly edible, woody subshrub that is related to okra in the Mallow family. In tropical and subtropical regions around the world the leaves are consumed as a vegetable, a spicy version of spinach. They are used in food preparation, while the calyx and flowers are used as a flavoring, coloring and for making teas. The calyx is also used in making wine, jam, juice, jelly, and syrup, while also used as a spice. Rosella hemp, which is extracted from the stems, is a strong fiber that is used for making sacks, twine and cords. Location will dictate if it is grown an annual or a perennial. In USDA Plant Hardiness Zones 8 through 11, it can be grown as a herbaceous perennial. In Zone 3 through 7, it is a rapid growing annual. Blooming takes place from mid to late October, while its fruits will mature in November and December, again planting zones will dictate blooms. Needing a long growing season for the pods to mature, when planted in cooler planting zones there may not be a sufficient length of time for the plant to be productive. Cooler planting zones do not provide enough warm months. Roselle is a short day plant and needs 12 or more hours of darkness to promote abundant flowering. Young foliage is a simple single-lobed leaf. As the plant grows larger, the young leaves will mature into three to five lobed leaves. It can be grown in containers or in the ground. Germination is very rapid. Its deep root system makes this plant quite drought tolerant. Its bright red stems and red veined leaves make quite a statement in the garden.
