Origin & Breeding History: 'Appletini' originated from a controlled cross conducted by the breeder, Hans Hansen, in Zeeland, Michigan, USA on January 30, 2012. The cross was conducted between two unreleased proprietary hybrids, 11-8-1, as the female parent, and K11-52-16, as the male parent. During the spring of 2013, 'Appletini' was selected for its flower colour, foliage colour, plant growth habit, heat tolerance, number of flowers and vigour. 'Appletini' was first propagated asexually using stem cuttings in the fall of 2014.
Tests & Trials: The comparative trial for 'Appletini' was conducted outdoors during the summers of 2018 and 2020 at Variety Rights Management in Oxford Station, Ontario. The trial included 20 plants of 'Appletini', 19 plants of 'Citronelle' and 20 plants of 'Pretty Pistachio' in both trial years. The plants were grown in 16 cm pots with 40 cm spacing between pots under a galvanized steel structure covered with black mesh shade fabric. The observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Data on the flowering characteristics was collected in 2020. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
