This looks like bindweed, probably Convolvulus arvensis. Very common invasive species in MI, officially designated as "noxious weed". It seems to be very hard to get rid off once established.
I too am rather fond of it, it is a common native wildflower where I grew up, but, no, I would not recommend introducing this into your garden in the US.
