Origin & Breeding History: 'Peakeep' originated from a controlled pollination conducted in 1988 between an unnamed female parent and the male parent 'Pink Delight' at the breeder's nursery in East Malling, United Kingdom. The new variety was selected based on its dwarf, compact habit and superior branching. The new variety was first propagated by softwood cuttings in 1994, in East Malling, West Malling, United Kingdom.
Tests & Trials: Tests and trials for 'Peakeep' were conducted in an outdoor container trial in the summer of 2004-2005, in St. Thomas, Ontario. The trial included a total of 15 shrubs of each variety. All shrubs were grown from 4 inch liners, planted into 2 gallon containers in May 2004 and transplanted into 3 gallon containers July 2, 2004. Trials were arranged outdoors in rows with approximately 1 metre spacing between plants. Observations and measurements were taken from 10 plants of each variety on July 6, 2005. All colour measurements were made using the RHS Colour Chart 2001.
