UPPER SIDE OF LEAF BLADE: dark green, weak rugosity, medium glossiness, no pubescence

CALYX: no petaloid lobes, position of lobes relative to pedicel is somewhat spreading
COROLLA: natural attitude is moderately outwards, rotate form, only one whorl, medium to large diameter, very short

COROLLA TUBE: as proportion of corolla length the tube is short to medium length, very short, when viewed in profile sides are strongly diverging towards opening, narrow opening, violet blue (RHS 93B) outer side, colour of inner side is not markedly different than colour of outer side.

STAMEN: pollen absent

Origin & Breeding History: 'PKM02' originated from a hybridization between an un-named selection from a breeding line of Campanula isophylla and an un-named selection from a breeding line of Campanula carpatica. The hybridization was conducted in May 2009 by Christian Hald Madsen in Sorhus, Denmark. 'PKM02' was selected in November 2012 for its attractive plant growth habit and violet flowers.

Tests & Trials: The detailed description of 'PKM02' is based on the UPOV Report of Technical Examination, application number 2012/2546, purchased from the Community Plant Variety Office in Anger, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2013. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
