ratwick Posted September 13, 2009 Agave americana 'Glauca' under windows is a nice, lethal touch. Euphorbia tirucalli (Pencil Tree) won't stop entry, but will leave the intruder with blistered and scarred eyes and skin to give them something to remember you by People love shade trees, but I hear that intruders like to use them to their advantage. Solution: Plant a Chorisia speciosa. Good luck climbing this tree: All stuff for warmer drier climates. Wow, What an awesome tree. I'd love to have one of those growing im my yard.
