Leek 'Kong Richard'

Allium porum, Leek 'King Richard'

A particularly early cropping variety that can be lifted by July from the very earliest sowings, but will easily stand until Christmas from a later sowing. The long, slender stems of Leek ‘Kong Richard’ are full flavoured and ideal for slicing. This RHS AGM variety can also be grown close together for delicious, succulent mini leeks, but is best harvested by Christmas as it is less hardy than some other varieties. Height: 45cm (18”).
