Origin & Breeding History: 'Leumayel' was developed by the breeder, Manfred Mehring-Lemper, in New Eichenburg, Germany. It originated from an open pollinated cross between the female parent designated 'S055' and a mixture of pollen from a population designated '65-86' which took place in 1999. 'Leumayel' was selected in June of 2000, based on criteria for flower quality and quantity, flower colour, leaf shape and plant vigour.

Tests & Trials: The test and trial for 'Leumayel' was conducted in a poly-house during the spring of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on April 20, 2006. Observations and measurements were taken from 10 plants of each variety on July 14, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
