Varieties used for comparison: 'PKMP05', 'Moon' and 'Planet'
Summary: The lobes of the calyx of 'PKMP08' are somewhat spreading while those of 'Planet' are weakly reflexed. In profile, the sides of the corolla tube of 'PKMP08' are slightly to strongly diverging towards the mouth while those of 'PKMP05' and 'Planet' are parallel to slightly diverging. In cross section, the corolla lobe of 'PKMP08' is weakly concave at the mid-point whereas the corolla lobes of 'PKMP05' and 'Moon' are weakly convex at the mid-point. The central furrow on inner side of the corolla lobe is weak for 'PKMP08' while it is strong for 'PKMP05'. The corolla lobe of 'PKMP08' has absent or very weak reflexing whereas the corolla lobe of 'Moon' has medium to strong reflexing. The corolla lobe of 'PKMP08' is broad elliptic whereas it is narrow elliptic for 'Planet'.
PLANT: flat rounded growth habit, medium to dense branching, very short to short, narrow to medium width

CALYX: no petaloid lobes, angle of lobes somewhat spreading
COROLLA: attitude is moderately outwards, campanulate form, single type, small diameter, very short
COROLLA LOBE: broad elliptic shape, short, very narrow to narrow at widest point, absent or very weak reflexing, no twisting, mid-point in cross section is weakly concave, central furrow on inner side is weak, obtuse tip, inner side is between violet (RHS N87A) and blue violet (RHS N88A)
COROLLA TUBE: length relative to the corolla length is medium to long, short, in profile sides of tube are slightly to strongly diverging towards mouth, very narrow to narrow mouth, outer side is violet (RHS N87A)
Origin & Breeding History: The variety 'PKMP08' originated from a cross between two unnamed proprietary selections, '08.03' and '08.05', at PKM Nurseries in Sorhus, Demark in June 2007. The resulting seedlings were selected in August 2008 based on their compact and freely flowering habit, and dark purple flowers.
Tests & Trials: The detailed description of 'PKMP08' is based on the UPOV report of Technical Examination, application number 2010/1274, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2011. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
