'Yutang Xiangfei'

(20140109 (National Protected Plants, China)); (unlabeled publication, received November 17, 2015): 'Yutang Xiangfei' is a new upright round shaped white and fragrant flowered crape myrtle clone. This cultivar is adapted to conditions in USDA cold hardiness zones 6-9. It was selected for its Tea aroma and rounded form. This new hybrid is an ideal flowering shrub to highlight your garden pleasant and distinctive in summer.

'Yutang Xiangfei' resulted from a cross-pollination between L. indica 'Qiao Jiaren' as the female parent and L. caudata as the male parent. The new crapemyrtle was selected at the Nursery of National Engineering Research Centre for Floriculture in Beijing, China as a fragrant flowered seedling (X20) within the progeny of the stated cross-pollination. Seedlings were screened by growing under alternating stress conditions in Beijing (Zone 7) including full sun, cool spring nights, high humidity and summer drought. In addition to tea aroma flowers, the clone has a combination of other desirable horticultural traits including dense flower panicles over an extended bloom season, and attractive persistent green foliage.

'Yutang Xiangfei' is a deciduous, densely branched and round shrub that has grown 150 cm tall and 100 cm wide at 3 years of age under ambient field conditions in Beijing. Leaves are elliptical measuring 6 to 7 cm in length and 3 to 4 cm in width with an acuminate apex, cuneate base, and entire margins with 3 to 5 pinnate venations. Calyxes are 8 mm long, 6 apparent arris, and bell shaped. Flower buds are conical with secondary erumpent suture lines. Inflorescences average 30 cm in length and 15 cm in width, with 100 to 120 flowers per panicle. Flowers average 3.4 cm in diameter, with 6-mm-long claws, 6 petals, 9 mm long and 8 mm wide. Petals are fan shaped with ruffled apex, ruffled margins and sagittate bases. Flowers are generally colored White N155C. Flowers have full dimorphic stamens, with 6 short stamens and 30 to 40 long stamens. Flowering occurs from July to September. Fruiting occurs from October to November.

Suitable growing zone of 'Yutang Xiangfei' are ranged from Beijing to the south. Water and nutrient management, pruning and shaping, and pest control need to be pay attention in the process of nursery. The phenotype may vary slightly due to environmental changes such as light intensity and fertility with no alteration of genotype. The clone is easily propagated by softwood stem cuttings under intermittent misting systems. The best rooting material should be taken from actively growing stock plants. Asexually propagation of the clone over multiple cycles has demonstrated retention of major distinguishing traits." Breeders were Qixiang Zhang, Huitang Pan, Ming Cai, Yang Liu, Dan He, Wan Xu, Jia Wang, and Tangren Cheng at College of Landscape Architecture, Beijing Forestry University, Beijing, 100083, China.

Color designations are according to the Royal Horticultural Society Colour Chart 2001. Hardiness ratings are based on Plant Hardiness Zone Map of China, USDA. Name considered November 17, 2015.



(D.R. Egolf and A.O. Andrick, The Lagerstroemia Handbook/Checklist, AABGA, p. 66. 1978): Spreading shrub, fast growing; fls. light pink. Orig as F 2 open pollinated L. fauriei × L. indica select. in 1972 by Mrs. C.D. Tinsley, Houston , TX . Named and intro. in 1973 by Lynn Lowrey, Lowrey Nurs., Houston , TX .

'Zi Yan'

(unlabeled publication, received November 17, 2015): "'Zi Yan' is recommended for trial by nurserymen and horticulturists as a flowering woody landscape plant in China. But winter protection will be needed under extreme circumstances (Cold Hardiness Zone7-9). This cultivar was selected for its spreading plant shape, outstanding disease resistance, environmental stress tolerance, light purple flowers and extended flowering period.

Cross of L. fauriei × L. indica 'Creole' was made in 2011, planted in 2012 and first flowered in 2012. Sterile but reproducible only vegetatively. Deciduous and low-spreading shrub, 0.8m high and 1.4m wide in 3 years. Four-striate young shoots are red-purple (Red purple 59 A), spreading or weeping. Leaves are elliptical, dark green (green 137A), acute at the apex, obtuse to cuneate base, 4-6cm long and 2-3cm wide, 6-8 pairs of lateral vein, and have yellow (yellow-orange 20A to greyed-orange 163B) autumn color. The ovate panicles are 15-20cm long and 10-15cm wide, with 60-100 light purple (Red purple N74C ) florets, each 3.4cm in diameter, with long-clawed, crinkled petals, 6mm long, 11mm wide, and bloom from June to September. Compared with male parent, it has larger plant shape and more blooms. As a weeping ornamental plant, it will be a good garden tree in summer." Breeders were Huitang Pan, Yuanjun Ye, Qixiang Zhang, Ming Cai, Xing Hu, Wan Xu, Ke Wang, Tangren Cheng, and Jia Wang at Beijing Forestry University, Beijing, 100083, China.
