An exceptional variety that is early to crop and has a long picking season, 'Polestar' produces high yields of smooth runner bean pods that have a sweet flavour and crisp, fleshy texture. If not left too long on the vine, these beans are stringless, so for best taste and texture, pick when they reach 15-20cm (6-8in) in length. A reliable and long-standing favourite of vegetable growers, this heavy cropping variety will produce plenty of delicious fresh beans for your plate and plenty more for the freezer. Versatile and nutritious, they are a classic cooked veg, but the young beans also taste great raw - try shredding or slicing them into a salad or using as a baton for dips. For best results, sow the seeds indoors in pots from April to May for transplanting outside in May to June; or sow from April to May outdoors, directly into their cropping position. To get the growing season off to an earlier start, sow them in containers in your greenhouse. The plants produce pretty red flowers,
