Latin name of the genus and species of the plant claimed: Interspecific Chamelaucium hybrid (Chamelaucium megalopetalum×Chamelaucium uncinatum).

Variety denomination: ‘WX 56’.


‘WX 56’ is a new waxflower plant that originated as a seedling produced in a sexual breeding program conducted by the breeder at Medina and South Perth, Western Australia. ‘WX 56’ was selected from seedlings of a controlled cross of female parent Chamelaucium megalopetalum ‘CM 5.5’ (not patented), and male parent C. uncinatum ‘827/887-8’ (not patented). An embryo was excised from fruit produced in 2000 and germinated in vitro. The resulting seedling was subcultured in tissue culture four times, deflasked, hardened and planted in the field at the research station at Medina, Western Australia in May 2001. Following flowering in July 2002, the seedling was vegetatively propagated via cuttings and a second generation of cuttings taken in March 2003 at Medina, Western Australia. A subsequent generation was propagated vegetatively in 2009. Growth and flowering records of the generations were recorded from 2002 to 2005 and again in 2010. No off-types were recorded and all plants were found to be uniform and stable.

‘WX 56’ is distinguishable from its female parent ‘CM 5.5’ by a number of features, as described in Table 1 below:

TABLE 1 Characteristic CM 5.5 WX 56 Flower color White/pink aging White aging to pink to bright red and then red/purple Leaf length Short Medium Plant height Short Medium

‘WX 56’ is distinguishable from its male parent ‘827/887-8’ by a number of features, as described in Table 2 below:

TABLE 2 Characteristic CM 827/887-8 WX 56 Flower color Pink White aging to pink and then red/purple Leaf length Long Medium Leaf cross-section Round Flattened/triangular

‘WX 56’ is also distinguishable from other known waxflower varieties. Comparisons of ‘WX 56’ to ‘WX 58’ (not patented) and ‘Purple Gem’ (not patented), the most similar varieties of common knowledge, are set forth in Tables 3 and 4 below:

The following detailed botanical description is based on observations of four-year-old ‘WX 56’ waxflower plants growing at Medina, Western Australia during August and September (early spring) 2013, except where otherwise noted. All colors are described according to The Royal Horticultural Society Colour Chart (2001). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average.
