Overview

Allium cepa 'Red Candy Apple' is Red Candy Apple onion, a biennial grown as an annual for bulb production, 18-24 inches (45-60 cm) tall and 6-8 inches (15-20 cm) wide. Globe-shaped bulbs 3-4 inches (7-10 cm) diameter with burgundy to mahogany papery outer skins and white flesh with concentric purple-tinged rings. A red sweet onion: reduced sulfur compounds — mild enough to eat raw. The anthocyanin pigments are partially retained when cooked. Blue-green hollow tubular foliage. In the amaryllis family (Amaryllidaceae). An intermediate-day onion: bulbs at 12-14 hours of daylight (latitudes 32-42°N). F1 hybrid — seed does not produce true to type. Stores 2-4 months — shorter than pungent storage reds due to higher water content. Start seed indoors 10-12 weeks before last frost. Harvest when 50-75% of tops have fallen and yellowed (90-120 days from transplant). Cure 2-3 weeks. All Allium contain thiosulfates: toxic to dogs, cats, and horses. Deer-resistant. Full sun. Annual. Growth rate is moderate.
