Thornless Blackberries

Thornless blackberries are perennial plants with growth and fruiting habits. Blackberry plants grow in a spreading shrub habit and are classed as either erect or semi-trailing.  The tall, woody stems of thornless blackberry plants produce green foliage and fruit. Yields can be increased and fruit quality improved with proper care, which includes training and pruning.   This blackberry can be grown anywhere outdoors but it is considered a warm climate crop.
