Thornless Blackberry 'Satin' is a compact variety of Thornless Blackberry growing to around 1.5m by the end of the fruiting season.  It produces delicious sweet, blackberrys.  Hardy and easy to grow, they are cold and wind tolerant, and will grow in most soils. For best results, train along a fence or trellis, and prune after fruiting. They fruit on second year wood, so cut out old branches once they are done.
