Aeonium haworthii

 

In areas where this can be grown as a landscape plant, such as along the California coast, it's used extensively for that purpose...so much so that it's become one of those plants which people just give to each other as cuttings. And because of this, nurseries don't seem to carry it.

But, in our less hospitable climates, it's also a wonderful potted specimen. In the right place, it's a cool companion plant to the ever-present Jade.
