What is this? New House.

Hi. I just moved into a new house and the garden has these plants that have red and green clusters of kernels on a long thick stem. What are they? I want to know if they are poisonous, I have an 18 month old who loves to be outside.

Thanks for your help.

Thanks Ron B. I've done some research and this is exactly what it is.
