什么是龙舌兰

龙舌兰属多肉植物，具有相同的名称，属于大型植物属，属于龙舌兰科。
Chiefly Mexican, agaves occur also in the southern and western United States and in central and tropical South America.龙舌兰主要在墨西哥，也发生在美国南部和西部以及中南美洲和热带地区。 The plants have a large rosette of thick fleshy leaves, each ending generally in a sharp point and with a spiny margin;这些植物有一朵厚而肉质的叶子的大莲座丛，每节通常以一个尖点和多刺的边缘结束。 the stout stem is usually short, the leaves apparently springing from the root.粗壮的茎通常短，叶子显然从根中弹出。 Along with plants from the related genus Yucca, various Agave species are popular ornamental plants.除相关丝兰属植物外，各种龙舌兰也很受欢迎。
Each rosette is monocarpic and grows slowly to flower only once.每个莲座丛都是单生的，生长缓慢，只能开花一次。 During flowering a tall stem or "mast" grows from the center of the leaf rosette and bears a large number of shortly tubular flowers.在开花期间，高的茎或“肥大”从叶丛的中心生长，并带有大量的短管状花。 After development of fruit the original plant dies, but suckers are frequently produced from the base of the stem which become new plants.果实发育后，原始植物死亡，但经常从茎的基部生产吸盘，成为新的植物。
It is a common misconception that Agaves are cacti.人们普遍误认为龙舌兰是仙人掌。 Agaves are closely related to the lily and amaryllis families, and are not related to cacti.龙舌兰与百合和孤挺花家族密切相关，与仙人掌无关。
龙舌兰物种被包括鳞翅目Batrachedra striolata在内的某些鳞翅目（蝴蝶和蛾）物种的幼虫用作食用植物，这已经在A shawii上进行了记录。
