I was suprised to not see Sago's listed. I bought one from Lowe's and was just getting ready to put it in the ground when I decided to check here first. Good thing I did! Experiences here made me return the plant. My Lhaso Apso loves to accompany me in the garden and she inspects everything I do to make sure it meet her approval. Please keep it away from your precious pets!!
King sago??? They are all over the place where I live and I have never heard of a problem. I don't see why anything would even try and eat those I can't prune it without some sticking my self. I would say Yucca are dangerous and I didn't see those on the list either. Common to use them around here for a security fence.
