The new cultivar was selected from the progeny in May 2005 based on remontant flowering, large inflorescences, and sepal colour.

Tests & Trials: Trials for 'Shugert' were conducted during the spring of 2011, in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate and reference varieties. All shrubs were grown from young plants transplanted in 3 gallon containers in the spring of 2009. Observations and measurements were taken from 10 plants of each variety on May 19, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
