Pots filled with soilless, pinebark based mix with controlled release fertilizers. Appropriate pest and disease treatments were applied as required. Trial Design Twelve pots of each variety in a completely randomised design. Measurements From ten plants randomly selected. RHS Chart - edition 1995 Origin and Breeding Controlled pollination: ‘Winter Lace’ x ‘Boysenberry Ruffles’. Pollination occurred in Wonga Park, VIC Australia in Nov 2005. This has been part of an ongoing Lavandula breeding program designed to develop plants with shorter flowering stem length and large infertile bracts. From this cross the generation was raised in Feb 2006 and grown to flowering maturity in 140mm containers in Sep 2006. Selection criteria: Plant: size small to medium; Infertile bract: red-purple RHS 74C, length short to medium. Propagation: the seedling, after being isolated, was then propagated via cuttings to establish trial stock plants. This initial and two subsequent generations were all found to be uniform and stable. Final selection for commercialisation occurred in Sep 2007. Breeder: Plant Growers Australia Pty Ltd.
