Red Windsor is a sport (naturally-occurring mutation) discovered in 1985 in Worcestershire, of Alkmene, a 1930s German cross between Cox’s Orange Pippin and Duchess of Oldenburg. It has a Cox-like flavour and acidity, but it is juicier than Cox, with an attractive red skin, and very crisp. It ripens in early-mid September. It is easy to grow, a reliable cropper, and it is self-fertile and so needs no pollination partners. The blossom has a degree of frost resistance, and the tree is unaffected by apple diseases such as scab and canker. It is also known as Sweet Lilibet.
