Confusion Risk

The following plants look similar and may be confused:

Euphorbia species Euphorbia spp.

Visually similar in some succulent growth forms; Euphorbia species are highly toxic and produce irritating milky sap, which Aeonium arboreum does not secrete.

Other Crassulaceae species Crassulaceae family (various genera)

Share similar succulent rosette growth traits as members of the same plant family; most other Crassulaceae species are also non-toxic.
