Origin & Breeding History: 'Hormeteoric' originated from the cross made in 1994 between the female parent, 'Anna Ford' and the male parent, 'Euphorbia' in Stanstead, Essex, UK. In 1995, a single plant was selected from the progeny based on flower colour and abundance, attractive foliage, growth habit and good black spot resistance.

Tests & Trials: Field trials were conducted during the summer of 2008 in St. Thomas, Ontario. There were 8 plants of each variety planted in May 2007 in rows with plants spaced 2 feet apart and rows spaced 3 feet apart. All colour measurements were made using the Royal Horticultural Society Colour Chart 2001.
