Origin & Breeding History: 'VUKOZ041323' originated from a controlled cross conducted by the breeder, Vojtech Benetka, in Pruhonice, Czech Republic in 2004. The cross was made between a proprietary plant designated 93-14-42 and the male parent 'Volans'. From the resulting progeny, 'VUKOZ041323' was selected as a single plant in the summer of 2008 based on its yellow flower bud colour, white flowers with a yellow patch in the centre, number of flowers, and reblooming performance. 'VUKOZ041323' was first asexually propagated by softwood cuttings in the summer of 2008 in Pruhonice, Czech Republic.

Tests & Trials: The comparative trial for 'VUKOZ041323' was conducted outdoors during the spring and summer of 2020 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 12 plants of the candidate variety and reference variety. All plants were grown from 10 cm rooted liners that were each planted into a 7.5 litre container on August 6, 2019. The plants were overwintered in a polyhouse and moved outdoors in late May of 2020 to a drip irrigated field where they were arranged in rows with approximately 1 metre spacing between plants. Observations and measurements were from 10 plants or parts of plants of each variety on May 15, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
