We call it morning glory, but the books call it Field Bindweed. It
is a European native, now naturalized over a lot of North America.
It is difficult to eradicate because of its very deep rhizomes, which
also help it to thrive in our dry summers.
In Victoria, it is present in most very old gardens, in areas built
over a century ago, but not in areas that have been developed more
recently than that. When people offer plants to friends, other weeds
often hitchhike, but morning glory doesn't seem to, I guess because
the rhizomes are so deep.
