Origin & Breeding History: 'Baldelmim' originated from an open pollination conducted during July 1999 at Rijsenhout, The Netherlands. The female parent was a proprietary dahlia breeding selection designated 3236, characterized by its white flower colour, medium green foliage and semi-upright growth habit. The initial selection was made in September 2000 and asexual propagation since that time has been through the use of vegetative cuttings. Selection criterial included flower form and growth habit.

Tests & Trials: 'Baldelmim' was tested in an outdoor trial during the spring/summer of 2008 in St. Thomas, Ontario. The trial consisted of a total of 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on May 15, 2008. Observations and measurements were taken from 10 plants of each variety on June 26, 2008. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
