Sunflowers are taking over

When I first planted these, they were in a football-sized clump. Now, they seem to be threatening to take over the side of the house.


I’ve wondered if they would do better out in the open where they could grow stronger. Where they are now, they only grow so high before they start falling over. They’ll need to be divided in the spring, so I guess we have until then to decide where to put them.
