Incidentally, the stuff around your hydrangea is not clover, it is creeping Charlie (aka ground ivy), a common lawn weed.
Some people consider it a pest, but bees like those flowers, and it is in the mint family and edible:
Young leaves can be eaten raw or cooked. The leaves have a mild bitter flavour and can be tossed into salads to add a slight aromatic tang. They can also be cooked like spinach, added to soups, stews, or omelet. Tea is made from the fresh or dried leaves. https://www.ediblewildfood.com/creeping-charlie.aspx
It has been used as a medicinal herb.
