白玉兰是落叶乔木,高达25米,径粗可达200厘米,树冠幼时狭卵形,成熟大树则呈宽卵形或松散广卵形。实生起源的大树常主干明显,树体壮实,雄奇伟岸,生长势壮,节长枝疏,然花量稍稀。嫁接种往往呈多干状或主干低分枝状特征,节短枝密,树体较小巧,但花团锦簇,远观洁白无瑕,妖娆万分。故不同起源之白玉兰园林应用中情趣各异,在小型或封闭式的园林中,孤植或小片丛植,宜用嫁接种,以体现古雅之趣;而风景游览区则宜选用实生种,以表现粗犷纯朴的风格。
白玉兰幼时树皮灰白色,平滑少裂,老时则呈深灰色,粗糙开裂。小枝灰褐色。顶芽与花梗密被灰黄色长娟毛,毛绒绒如幼鼠蛰伏,冬态更显。分枝习性随树龄幼长有别,幼时单芽延伸,故主干明显,树冠规整,而见花后,叶枝混合芽在果穗后双杈或多枝延伸,横向发展盛于直于生长,故树冠往广卵形方向发展
叶片互生有时呈螺旋状,宽倒卵形至倒卵形,长10—18厘米,宽6—12厘米,先端圆宽,平截或微凹,具短突尖,故又称凸头玉兰;中部以下渐狭楔形,全缘。玉兰叶在基部通常有托叶或附属物,托叶有两种,枝端芽末的托叶贴生于幼茎上与叶柄分离,呈覆瓦状;叶部托叶散生,瓦刀状,粘着叶柄基部两侧,芽伸叶长,托叶脱落,幼枝上残存环状托叶痕,此为木兰科树种的识别特征。
