Trachelospermum jasminoides

藤本植物,在上海为自然分布A climbing vine that grows naturally in Shanghai

常绿木质藤本,靠茎上生出的气生根攀附墙面、山石和树干,「络石」的名字就是缠络于石之意。它在上海及华东一带为自然分布的本土物种,并非引进的园艺植物。An evergreen woody vine that clings to walls, rocks and tree trunks with aerial roots along its stems — its Chinese name means “wrapping around stone”. It is a native species that grows naturally in Shanghai and East China, not an introduced garden plant.

初夏开白色小花,五枚花瓣向同一方向旋扭,像一个个小风车,香气浓郁,傍晚尤盛。需要注意:它属夹竹桃科,折断的枝叶会流出白色乳汁,有毒,请不要采摘或让孩子放入口中。In early summer it bears small white flowers whose five petals twist in the same direction like tiny pinwheels, with a strong scent that is richest in the evening. Please note: it belongs to the dogbane family, and broken stems and leaves ooze a poisonous white sap. Do not pick it, and keep children from putting it in their mouths.
