Variety Description
Varieties used for comparison: 'Valley Rose' and 'Mountain Fire'
Summary: The natural plant height of 'Piesid2' is shorter than that of 'Valley Rose'. The plants of 'Piesid2' are narrower than those of 'Valley Rose' and wider than those of 'Mountain Fire'. The leaf blade of 'Piesid2' is larger than that of both reference varieties. The pedicel of 'Piesid2' is longer than that of both reference varieties. The inner side of the sepal of 'Piesid2' is red pink over a light yellow brown ground colour whereas that of both reference varieties is light yellow. The arrangement of the corolla lobes of 'Piesid2' is free whereas for 'Mountain Fire' they are overlapping. The corolla of 'Piesid2' is wider than that of both reference varieties. The secondary colour of the inner side of the corolla lobe of 'Piesid2' is dark blue pink and light red pink at the apex with dark brown along the margin whereas that of 'Valley Rose' has medium blue pink to light blue pink at the apex and that of 'Mountain Fire' has no secondary colours present.

Origin & Breeding History: 'Piesid2' originated as a naturally occurring branch mutation that was discovered and developed by the breeder in Mission, British Columbia, in the summer of 2016. The mutation was discovered on a plant of the Pieris japonica variety 'Valley Rose' growing in a block of 1 gallon containers. The new variety was selected as a single unique seedling based on the new leaf colour. Asexual reproduction of 'Piesid2' was first conducted by tissue culture in the spring of 2018, in Mission, British Columbia.
Tests & Trials: The comparative trial for 'Piesid2' was conducted in a polyhouse during the spring of 2021, at BioFlora Inc., in St. Thomas, Ontario. The trial included 10 shrubs each of the candidate and reference varieties. All shrubs were grown from rooted cuttings and transplanted into containers in the early spring of 2021. Observations and measurements were taken from 10 plants or 10 parts of plants of each variety on May 10, 2021 (for flowers) and June 23, 2021 (for summer plant and leaf characteristics). All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
