Product description
Johnsons 'Exhibition' Onion Seeds are a superb choice for growers aiming for show-quality results or large, flavoursome kitchen onions. This variety rivals the renowned 'Kelsae' strain, producing well-shaped, golden bulbs with a mild, sweet flavour—even at impressive sizes up to 6 inches across. For optimal results, sow indoors from December to February in seed compost, maintaining a temperature of 15–20°C. Transplant seedlings once large enough to handle, spacing 30cm apart. Alternatively, sow outdoors in spring directly into finely prepared soil. Onions mature by late summer and store well in cool, dry conditions. Whether you're entering competitions or enhancing your home cooking, 'Exhibition' delivers size, flavour, and reliability for UK gardeners.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
