美国皂荚(Gleditsia triacanthos)为豆科云实亚科乔木,曾作为观赏树种、防风林、饲料和绿篱广为栽植。生长速度中等,木材硬、坚固、很抗腐。耐低温、干旱和盐。荚果含糖量丰富,人、家畜和野生动物均喜食。 美国皂荚树冠开阔,顶端平展,典型的美国皂荚高达24米,直径达60～90厘米。虽有一些雌雄同株的类型,但是大部分树还是雌雄异株。野生树的树干和枝条通常长有枝刺,春天,这种树开出小的略呈绿色的香花,而在秋天则结成扁平的弯曲的荚果。 分布:适于寒冷地区生长。在北美,从安大略到克萨斯都有分布。在欧洲已经安家落户,同时也被引种到非洲,澳大利亚、新西兰和南美的一些地方。

Low temperature, drought and salt. Pod rich in sugar content, people, livestock and wildlife are eating. The United States has the largest openable canopy pods, the top flat, the typical American pods up to 24 meters, diameter of 60 to 90 cm. Although there are some hermaphrodite types, most of the trees are dioecious. The branches and branches of wild trees usually have spines, and in spring, the tree gives off a slightly greenish, fragrant flowering flower, while in the fall, flattened curved pods are formed. Distribution: suitable for cold area growth. In North America, there is a distribution from Ontario to Texas.
