Some people keep it in the yard for the blue flower. It is similar to the houseplant wandering jew but the dayflower leaves are not colorful

It looks like the summer annual Asiatic Dayflower (Commelina communis), which is generally considered a weed. Did you dig it from the garden last fall?
They can be very invasive in the garden and are best removed by digging all the root. However, they produce a small blue flower that is pretty.

I got it from my cousin, who got it from her friend who seems to have a green house. So I’m nurturing a weed? Lol
