I just bought my house last summer and I have no idea what this bush in my yard is that has pink buds that open into green leaves. I live in Michigan where we've had a cold spring so it's just now starting to leaf out.
I'm pretty sure this is Chaenomeles, probably Chaenomeles superba 'Pink Lady', which is almost thornless; the flowerbuds are dark pink but open to a paler pink. If the flowers are pollinated, then you should get some fruits later in the year, but quite often, there are no fruits at all, or just one or two. https://mikesgardentop5plants.wordpress.com/2013/04/18/flowering-quince-chaenomeles/. If you don't mind losing fruits, this plant is best pruned directly after flowering, if you want to reshape or reduce its size. Doing so should create a bushier plant.
