RHS Onion Spring Matrix Seeds produce a reliable, winter hardy spring onion variety that is slow to form bulbs, ensuring long, straight stems that remain tender and full of flavour for an extended harvest period. This dependable variety is ideal for gardeners who want a steady supply of high quality spring onions across much of the year.

Matrix is particularly valued for its strong disease resistance, helping plants stay healthy and productive even during cooler, wetter conditions. The crisp white shanks and fresh green tops are perfect for salads, soups, stir fries and everyday cooking, delivering mild onion flavour without overpowering dishes.

This variety performs exceptionally well when sown little and often, allowing for continuous cropping from early summer through to late autumn, with later sowings overwintering to provide valuable early spring harvests. Its winter hardiness makes it an excellent choice for UK gardens and allotments.

Awarded the RHS Award of Garden Merit, Onion Spring Matrix has been recognised for its reliability, performance and consistency. It is suitable for outdoor sowing in prepared beds and requires minimal maintenance once established.

Part of the trusted seed range produced by Mr Fothergill’s Seeds in partnership with the Royal Horticultural Society, these seeds are packed in the UK and meet strict quality standards.
