Cultivated for its edible seed pods, harvested when immature Seeds soaked overnight prior to planting 1-2cm deep, germination occurs between 6 days and 3 weeks, pods appear about 50 to 60 days after planting Requires a long, warm and humid growing period (between 24°C and 28°C) Sensitive to frost and extremely low temperatures Soil: loose, friable and well manured, pH 6.0-6.8 is ideal Prone to damage from insects, fungi, nematodes, and viruses (i.e. ants, aphids)


Fruit eaten raw, pickled, or cooked Ornamental plant

Thicken stews, gumbo

In the South, used as a staple vegetable, and in many recipes (stew, gumbo, etc.) Frenchmen formed alliances with Native American tribes (mainly in the south), introduced them to okra Chickasaw word for okra is "kombo"


A slimy goop called mucilage is found in okra pods, its viscosity increases as heat is applied The mucilage is good at thickening To get rid of the slime: keep it whole (cutting releases the slime), add lemon or lime juice when boiling, cook it long enough so it disappears, cook with tomatoes (acidity)
