The inflorescence of 'Apache Rose' is smaller, with a weak intensity of anthocyanin colouration, than that of 'Prairie Fire', which has no anthocyanin colouration. When fully expanded, the lower side branches of the inflorescence of 'Apache Rose' are semi-erect while those of 'Prairie Fire' are horizontal.
Description:
PLANT: erect growth habit, narrow upright shape
STEM: lignified, thin at base, light green to medium green, absent or very sparse pubescence
LEAF: alternate arrangement
LEAF BLADE: linear shape, light green to medium green on upper side in the summer, yellow green to tan on upper side in the fall, concave shape in cross-section, twisted shape in longitudinal section, semi-erect attitude relative to main stem axis with some tips slightly arched, entire margin, acute apex, absent or very sparse pubescence
INFLORESCENCE: panicle type, weak intensity of anthocyanin colouration when fully expanded, semi-erect attitude of lower side of branches
Origin & Breeding History: 'Apache Rose' originated from a line crossing conducted and monitored by Hans Hansen of Walters Gardens Inc. in Zeeland, Michegan. The cross was made between the female parent 'Cheyenne Sky' and an open pollinated proprietary male parent in the summer of 2010. The selection process used was a pedigree selection for a compact and upright growth habit with dense culms, airy rosy-red panicles and grey-green foliage that develops rosy-red flushed tips in the fall. 'Apache Rose' was initially selected for further evaluation in the spring of 2012 and first asexually reproduced through division in 2012.
Tests & Trials: The comparative trial for 'Apache Rose' was conducted in a 50% shade polyhouse in 2016 at Variety Rights Management in Oxford Station, Ontario. The trial included a total of 11 plants of the candidate variety and 12 plants of the reference variety. All plants were grown in 23 cm pots and spaced 75 cm apart. Observations and measurements were made on 10 plants, or parts of plants, on October 16, 2016 and again on November 9, 2016 to assess further plant and foliage characteristics. Colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
