Overview
Allium cepa 'Candy' is a superior sweet storage onion cultivar renowned for its exceptional flavor profile and outstanding keeping quality. This variety produces impressive, uniformly globe-shaped bulbs that typically measure 3-4 inches in diameter at maturity, featuring attractive golden-brown papery outer scales that protect the crisp, white to pale yellow flesh beneath. The bulbs are characterized by their mild, sweet flavor that makes them particularly desirable for both fresh consumption and culinary applications.
The plant develops the characteristic hollow, cylindrical blue-green foliage typical of onions, with leaves emerging directly from the underground bulb and reaching 18-24 inches in height. The waxy, smooth leaves taper to sharp points and have a distinctive cylindrical form. When allowed to bolt, Allium cepa 'Candy' produces tall flowering stalks topped with spherical umbels of small white flowers, though most gardeners harvest the bulbs before the flowering stage to maximize bulb development and storage potential.
Native Range
Allium cepa originates from the mountainous regions of Central Asia, particularly areas encompassing modern-day Iran, Afghanistan, and Pakistan, where ancestral wild forms continue to thrive in their natural highland habitats.Suggested Uses
Allium cepa 'Candy' excels in vegetable gardens, raised bed systems, and container gardening applications. This sweet storage cultivar is particularly valuable in culinary gardens where fresh, mild onions are desired for cooking and food preparation. The variety works well in succession planting schemes to ensure continuous harvest throughout the season. Due to its excellent storage characteristics, it's ideal for gardeners seeking to maintain a winter onion supply. The attractive foliage also makes it suitable for ornamental vegetable gardens where aesthetics matter alongside productivity.How to Identify

Care & Maintenance
Care Guide
Allium cepa 'Candy' thrives in full sun exposure and demands well-draining, fertile soil for optimal bulb development and size. Plant in loose, organic-rich soil amended with compost to ensure proper drainage and prevent bulb rot, which can be devastating to the crop. Maintain consistent moisture throughout the active growing season, providing approximately 1 inch of water weekly through irrigation or rainfall. As bulbs approach maturity and the foliage begins to yellow naturally, gradually reduce watering to allow proper curing. Apply a side-dressing of compost or balanced fertilizer during mid-season to support continued bulb enlargement. Maintain excellent weed control throughout the growing period, as onions are poor competitors and weeds can significantly reduce yields.Pruning
Allium cepa 'Candy' requires minimal pruning intervention during the growing season. Remove any flower stalks (scapes) that develop to redirect the plant's energy from seed production back into bulb development and enlargement. Resist the temptation to cut back or trim the foliage during active growth, as the leaves continue photosynthesis and feed the developing bulb until they naturally begin to yellow and fall over. Once the tops have died back completely, harvest the bulbs and cure them in a warm, well-ventilated location to develop the protective outer scales necessary for long-term storage.Maintenance Level
