Azaleas (Rhododendron azalea) are one of the most popular ornamental plants in northern Taiwan. Hirado azalea is currently the most commonly used cultivar in the landscape, due to its vigorous growth, well flowering and high propagation rate. Petal color of Hirado azalea flowers range from purple to white. To widen the uses of azaleas in landscape, we used indigenous resources to produce new azalea cultivar suitable for northern Taiwan climate. After hybridization, individual selection, line comparison tests for two consecutive years, variety denomination and DUS tests (test for Distinctness, Uniformity and Stability), a line TYR0401009 was selected and thereafter named 'Taoyuan No.2-Torch'. 'Taoyuan No.2-Torch' has the overall appearance of single flower, salmon pink petals with wavy margin, good performance and leaves with long trichomes. Plant Variety Right of 'Taoyuan No.2-Torch' was granted from Sep.11, 2013 to Sep.11, 2038.
