Origin & Breeding History: 'Caltraelbu' originated from a controlled cross in 2003 between the female parent identified as Z4012 and the male parent identified as C4462. The cross was conducted by the breeder J. Oud in Enkhuizen, The Netherlands. The new variety 'Caltraelbu' was selected from the resultant progeny as a single plant in 2004 based on plant growth habit, flower colour and time of flowering. Asexual reproduction by cuttings was first conducted in August 2004 in Enkhuizen, The Netherlands.
Tests & Trials: Trials for 'Caltraelbu' were conducted in a polyhouse during the spring of 2008 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 23, 2008. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 22, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
