Origin & Breeding History: 'Lostrahob' originated from a cross of the female parent identified as E1080-1 and the male parent identified as D0041-1 conducted in Enkhuizen, the Netherlands in July 2004. The new variety was bred and developed by the breeder Theodorus C.M. van Keinwee as part of a controlled breeding program. The resultant seed from the cross was collected and sown in a greenhouse in Enkhuizen in February 2005. A single plant was selected from the progeny in May 2005, in Enkhuizen based on flower colour, flower size, plant vigour, plant growth habit and outdoor performance including heat tolerance.
Tests & Trials: Trials for 'Lobstrahob' were conducted in a polyhouse during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 19, 2011. Observations and measurements were taken from 10 plants of each variety on May 17, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
