Cabbage 'Hispi' F1 Hybrid (Summer)

Brassica oleracea (Capitata Group)

 Customer Rating
Versatile Summer Cabbage 'Hispi' can be grown at virtually any season of the year and comes to maturity faster than cabbages bred for specific seasons. Even autumn sown, it will beat the earliest of the spring cabbages and a Jan/Feb sowing will also fill the late spring gap in cropping. This RHS AGM variety is a strong and uniform pointed type, with a beautifully sweet flavour. Cabbage 'Hispi' has good bolt resistance and needs little growing space so it is ideal for growing in small gardens where space is at a premium. Height: 40cm (16"). Spread: 60cm (24").
