I've had no luck with planting my favorite flower, tulips, around the trunks of my three poplars. They start to come up beautifully in early spring and then I find the leaves are all chewed up. I'm lucky if any actually flower...maybe two or three survive. So I found out on this site that it's the squirrels and possibly the deer that we also have in our area, but no wild rabbits. So my question is: what other bulb or even perrenial flower can I plant around my poplars that won't attract squirrels or deer?
