A couple of years back, I had planted several Autumn Ferns (Dryopteris erythrosora) between the Cast Iron Plants (Aspidistra elatior) and the bed's rock border, but the ongoing drought hammered them into submission. So I decided to try planting five Wavy Scaly Cloakferns (Astrolepis sinuata) as they are rumored to handle low water conditions better.
Then I transplanted four Soap Aloe (Aloe maculata) pups along the highest point of the top level of my Three Tiers Bed. I had originally planned on placing a couple of Agaves here, but tree roots prevented me from replacing the original soil with enough good drainage for them.
Instead, I placed one of the Variegated Thread Leaf Agave (Agave schidigera 'Shira Ito No Ohi') into the front of the lowest level tier where one of my Agave 'Blue Glow' had died. I have one Agave left and will likely place it into a pot.
