Some types of Houseleek will also grow as epiphytes on the trunks of palm trees.

Love your fabulous hubs about the herbs of Tenerife. My cousins just got back from yet another cruise and once again went to the islands. They've even stayed with friends on Canary Island. Usually, I get to live vicariously which is fine too.

Rated up! Yay!
