Description
Raphanus sativus ‘Red Radish’ is a popular, fast-growing root vegetable in the mustard family (Brassicaceae). This cool-season annual is widely known for its crisp, pungent, and peppery flavor, which comes from compounds like glucosinolates. The plant forms a rosette of lobed leaves above ground, while its edible part, a swollen taproot, develops below. The ‘Red Radish’ variety is distinguished by its vibrant red skin and typically round shape, though it can also be oblong. It is a favorite among gardeners for its quick maturation, often ready to harvest in as little as three to six weeks after planting, making it an excellent crop for beginners.
