How difficult is it to grow blue cohosh?

My mom really likes non-invasive, native plants that are also unique and I have been looking at blue cohosh lately and wondering a few things about it. 1) How difficult of a plant is it to grow? 2) Are the berries toxic to dogs? 3) Do birds and squirrels like to eat the berries and make a mess, or do they generally leave this plant alone? 4) Will it grow in Florida? 5) Will it sprout/bloom in April? The reason why I am asking all of these questions, is because I am thinking about trying to grow this particular kind of plant to give my mom for her birthday in April. Asking about whether or not it's toxic to dogs, because we have a dog, although the dog does not generally eat things off of plants and I'm asking the other questions because I'm not very good at growing things, unless they are easy to grow.
