Pak Choi is an unusual all year round veg that is becoming ever more popular with its use in oriental stir-fries and salads, it has a mild cabbage flavour.
Pak Choi 'Yuushou' is a green leaved variety that is great for overwintering as well as for maincrop sowing. (Green stemmed varieties have more flavour than the white stem ones).
It is very quick to crop (3-6 weeks), easy to grow and slow to bolt - a little star. It can be treated as a 'cut and come again' crop i.e. harvesting a few leaves at a time or the whole head can be lifted entirely or cut 2.5cm above ground level and left to re-sprout.
