I don't know why, but my cannas won't unravel it seems as if they continue growing, but are sown together with these little black dot looking things. They are aligned in the center of the plant. It looks like it's eating the plant as well. Please help me.

I have always heard them called Leaf-rollers. If you break the webbing and carefully unravel the leaves, you will find the worms. Put some kind of bug poison on it to kill the worms or you will have no blooms. I fight them every year.
