Castor Aralia and Aralia Elata Posted byLance Kleckner October 3, 2005December 30, 2022 Leave a comment on Castor Aralia and Aralia Elata I am trying a couple different thorny trees that are from Asia. Castor Aralia(Kalopanax pictus) and Japanese Angelica Tree(Aralia elata). Both look very ornamental so far.
