Ailsa Craig Onion Seeds 1840 Heirloom Vegetable. This yellow skinned Spanish onion can reach 2.27 kg (5 lbs) in weight and 20 cm (8″) in diameter – which is very handy when it comes to the largest onion category at your local Fall Exhibition. The flesh is relatively mild and sweet making it ideal as a fresh use onion rather than for long term storage. This is also a very reliable performer in areas with shorter growing seasons. Introduced from Scotland in 1887.

How to Grow

280 seed/gram. Seed can be started indoors in a soil-less growing medium in February. The seedlings can then be transplanted outside later in spring. Seed can also be sown directly outdoors from mid April, 8-15 mm (1/4-1/2″) deep and 15 mm (1/2″) apart in rows 30 cm (12″) apart. Thin seedlings to 12.5 cm (5″) apart. Onions do best in a sunny site with fertile, well drained soil. Bend over any flower stalks that start to grow so the plant’s energy goes into building the bulb.
