Can anyone recognize this plant. It is growing in partial shade. I like this plant because it grows very fast and is quite large. I want to transplant it to an area I need more privacy. The leaves are almost 10 inches across and the plant is over 6 feet tall. I also would like to know if is OK to have around pets. I have a large dog who likes to investigate. Thanks.
Castor bean plant or Castor oil plant (Ricinus communis). This article describes the toxicity of the plant: http://en.wikipedia.org/wiki/Castor_oil_plant In short, the greens are mostly safe, whereas the beans may be fatal.
