Absolutely. That stuff will take over flowerbeds before you know it. And if you try to just pull it and break off little pieces, it spreads from the pieces. Annual morning glories are easy to control, you can just yank them out or snip them off at the base. If the flowers are little things, about an inch across, it's probably bindweed. If the flowers are much bigger, it could well be just the annual ones sprouting from seeds.
