Plant: Willow-leaved cotoneaster (Cotoneaster salicifolius) 柳葉栒子

The bright red fruit of willow-leaved cotoneaster (Cotoneaster salicifolius) drew my attention at The Los Angeles County Arboretum and Botanic Garden in January of 2023. It gave me a celebratory kind of joy. The alternate, simple, long, lanceolate leaves are resemble those of willow trees (thus the common name). It is native to western China (such as Sichuan, Yunnan, Hubei, Guizhou, Hunan). Masses of white flowers are produced in spring. The pictures below are the cultivar 'Rugosus'.
2023年一月在洛杉磯植物園參觀時,柳葉栒子 (Cotoneaster salicifolius) 鮮紅的果實吸引了我,它帶給我一種喜氣洋洋的感覺。互生、單葉,長披針形的葉子類似於柳樹,俗名因此而來。原產中國西部(如四川、雲南、湖北、貴州、湖南等地)。春天會開許多白色花朵。下面的照片是皺葉變種(又叫小葉山米麻,分布於湖北西部及四川東部)。
