Origin & Breeding History:
'Gentry' was discovered at the Leo Gentry Wholesale Nursery in Gresham, Oregon, United States in 1989. It was found growing in a bed of 15,000 container grown Barberis thungbergii of the variety 'Crimson Pygmy'. The plants in this bed were propagated by vegetative cuttings taken from several thousand mature 'Crimson Pygmy' plants growing at the nursery. Selection of 'Gentry' was based on the colour of its leaves, its ability to grow in full sun and resistant to sunburn or scalding with mid-day waterings.
Tests & Trials: Trials for 'Gentry' were conducted in a polyhouse during the summer of 2007 in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate and reference varieties. All plants were grown in 7.5 litre containers during the summer of 2007. Observations and measurements were taken from 2 year-old plants, 10 plants of each variety, on July 18, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
