Furcraea

Furcraea are very similar to Agaves when short stemmed but some have large stems making them resemble a large Agave on a trunk! F. macdougalii is just one of these tall trunked species. The flowers are also similar to Agave and Yucca which aint to bad in my humble opinion. A huge white spike of flowers on top of an Agave on top of a trunk!
