Should hydrangeas come back each year and if so what month?

I live in the midwest if that helps. Thank you!

in warmer regions they come up now. they need 70s for leaves to appear and no frosts. they will come up in a few weeks unless temps were below -15 f this winter if so it died and is only and annual in your zone
Reply:yes they will come back every year, mine is comming back now. I live in the east coast. mine is about 2 ft. tall also u can change their color but putting different things to them. also the soil in another part off your yard will change the color
Reply:as long as the frost and sub freezing temps do not kill them they should be blooming right now literally
Reply:They'll come up again every Spring, and last through most of the summer.
Reply:Yes, they are a perinnal and will come back each year. Mine are just now starting to "pop" out of the ground. I too live in the midwest.
