Wizo Trees’ owner Adrian Thorne started growing trees and shrubs in 2004 on a small scale. By 2008 some 12,000 trees, shrubs and woody climbers are growing in pots on land near Wiston, Pembrokeshire which was once the site of the Battle of Colby Moor in the English Civil war. Over 500 species and cultivars are stocked but not all are ready for sale at any one time.
