Origin & Breeding History: 'LOBZ0002' originated from a cross pollination conducted in Andijk, The Netherlands in February 2007 between the female parent identified as 'LOB07-244-2' and pollen from the male parent identified as 'LOB07-223-1'. The new variety was bred and developed by the breeder Eric Giesen, an employee of Syngenta Seeds B.B. in Andjik, as part of a controlled breeding program. The resultant seed was collected and sown in a green house in Andijk in May 2007. In July 2007, a single plant was selected based on flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'LOBZ0002' were conducted in a polyhouse during the spring of 2012 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 11 cm pots on April 23, 2012. Observations and measurements were taken from 10 plants of each variety on May 28, 2012. All colour determinations were made using the 2007 Royal Horticultural Sociey (RHS) Colour Chart.
