Origin & Breeding History: 'LOBZ0004' originated from a cross pollination conducted in Andijk, The Netherlands in January of 2007 between the female parent identified as 'LOB06-235-2' and pollen from the male parent identified as 'LOB1117-1'. The new variety was bred and developed by the breeder Eric Giesen, an employee of Syngenta Seeds B.V. in Andjik, as part of a controlled breeding program. The resultant seed was collected and sown in a greenhouse in Andijk in May 2007. In August 2007, a single plant was selected based on criteria for flower colour and plant habit.

Tests & Trials: Trials for 'LOBZ0004' 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 29, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
