Onion 'Supasweet'™ (Dulcinea) F1 Hybrid

Allium cepa

 Customer Rating

The first commercial variety of sweet and mild bulb onions available to UK gardeners! The large semi-globe, copper-skinned bulbs of Onion Supasweet™ are so sweet and juicy they can be eaten raw without being overpowering - ideal for adding to summer salads. Bulbs are best used as required, as they are not renowned for their storage capabilities.

Please note: Onion flavour (its sweetness and mildness) is significantly affected by weather conditions, soil type and its sulphur content. Light, sandy soils produce the highest levels of sweetness, whereas clay and dark humus rich soils can result in bulbs with a stronger flavour. Height: 45cm (18"). Spread: 10cm (4").
