Known as Kale-Rapes, these are forage Brassicas produced by crossing Kale and Rape to produce varieties which have the rapid establishment and quality of Rape combined with the higher yield and hardiness of Kale.
So far, the best are hardier and more Alternaria resistant than most Forage Rapes and slightly higher yielding, like Interval and Swift. Both are ideally suited to summer planting and winter use. Redstart is a variety selected for good resistance to bolting, Alternaria and Mildew. Normally used for spring planting and summer use, it has also proven good for autumn/winter use.
