Heat-treated Rosanna onion sets are a must-have for any vegetable garden or allotment. Bred specifically for the UK climate, the Rosanna has performed exceptionally well at recent trials. This modern hybrid onion is crossed with the Rose de Roscoff – a well-known heritage variety that was once sold door-to-door by traditional French onion sellers.

Boasting a unique sweet and fruity taste, Rosannas are impressive globe-shaped onion plants marked by a characteristic pink blush. This colour continues once peeled, revealing stunning rosy hues running right through the layers. With their melt-in-the-mouth flavour, these gourmet onions are perfect for eating raw in salads or adding depth to cooked dishes.

Our Rosanna onion sets are carefully heat-treated before despatch – an entirely natural process which takes several months. This ensures rapid establishment and growth, resulting in higher yields. It also virtually eliminates the risk of the onions prematurely running to seed or 'bolting'.

All of our onions are certified disease- and virus-free. Plant these particular onion sets outdoors in March and April and enjoy a bountiful home-grown harvest from August to September. 250g pack contains around 70 sets for planting.
