Origin & Breeding History: 'KLEOE05524' was developed by Nils Klemm in Stuttgart, Germany, originating from an open pollination between an unnamed proprietary seedling and an unknown male parent conducted in June, 2002. In May, 2003, 1200 seedlings were selected based on flower colour, growth habit and leaf colour. In April, 2004, one seedling was selected, named 'KLEOE05524' and was evaluated in greenhouse trials from 2004-05 for branching, flowering time, flower colour, growth habit and leaf colour.

Tests & Trials: The trials for 'KLEOE05524' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
