Origin & Breeding History: The variety 'Penda' originated from an open pollinated cross made in June 2004 at Grand Haven, Michigan, USA, between the female parent 'Josee' and an unknown male parent. The new variety was selected in the spring of 2006 based on repeat blooming, dark flower bud colour, flower colour and good tolerance to root rot. The new variety was first propagated by softwood cuttings in the spring of 2007 in Grand Haven, Michigan, USA.

Tests & Trials: 'Penda' was tested in a polyhouse in the early spring of 2010 and continued in an outdoor trial during the summer of 2010, in St. Thomas, Ontario. The trial consisted of a total of 12 plants of the candidate variety and 10 plants of the reference variety. All plants were grown from 4 inch rooted liners planted in 2 gallon containers in May 2009. Plants were spaced .5 metres apart and overwintered in a polyhouse. Observations and measurements were taken from 10 plants of each variety on May 10, 2010 and July 8, 2010. All colour measurements were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
