Before anyone asks if I have a Bulldog, no. The Bulldog is the mascot of my alma mater, The University of Georgia. The rope is tied to my trailer hitch-I pulled the Jeep into the garage and the offending Agave popped out. The other plant is a Firesticks Pencil Cactus, easily removed.
These days my side door is Agave free. I have thornless Desert Roses (Adenium obesum) in these pots underplanted with Flapjack Kalachoe and Fireball Bromeliads. The Roses flower in summer and look funky year round.
