Origin & Breeding History: 'Mediopimo' is the product of a planned breeding program conducted by the breeder, Ushio Sakazaki of Hikone Shiga, Japan. The objectives of the program was to create new trailing petunia varieties with unique flowers and greater disease resistance and heat tolerance. 'Mediopimo' originated from a cross made by the breeder on December, 1998 in Shiga, Japan, with the seed raised petunia variety 'Fantasy Pink Morn' as the female parent, and a wild petunia as the male parent. The F1 seed was collected and sent to Gensingen, Germany for further selection. 'Mediopimo' was selected as a single plant from the resulting progeny on September, 1999 in Germany. The new petunia was selected based on compact flower size.

Tests & Trials: Tests and trials for 'Mediopimo' were conducted in a polyhouse at BioFlora Inc., St. Thomas, Ontario during the summer of 2003. The trials included 15 plants of each variety. Rooted cuttings were transplanted into 15cm pots on April 25, 2003 (week 17). All colour measurements were made using RHS colour chart 2001. Unless otherwise indicated measured characteristics were based on ten measurements.
