Origin & Breeding History: 'Ruby Queen' originated from a cross between 'Victoria', as the female parent and a proprietary selection as the male parent. The cross was made in 1993 and the new variety was discovered and selected by the breeder as a single plant within the progeny of the stated cross, in a controlled environment in Boskoop, The Netherlands. The objective of the breeding program was to create new Weigela varieties having dwarf plant habit and dark coloured foliage. Tests & Trials: 'Ruby Queen' was tested in an outdoor container trial during the summers of 2004 and 2005, in St. Thomas, Ontario. The trial included 15 plants of each variety. All shrubs were grown from 5 inch liners, planted into 2 gallon containers in May 2004 and transplanted into 3 gallon containers on July 2, 2004. Plants were arranged in rows with approximately 1 metre spacing between plants. Observations and measurements were taken from 10 plants of each variety on June 7, 2005. All colour measurements were made using the 2001 RHS colour chart.
