Common questions

Is Japanese aralia related to castor bean?

Only by a confusing shared nickname. Fatsia is sometimes sold as "castor oil plant" in the ornamental trade, but true castor bean (Ricinus communis) is an entirely different and highly toxic plant.

Is the variegated Fatsia also safe?

Yes. Variegated cultivars contain the same non-toxic tissue as the plain green form.
