I don't know the actual names of these plants? I think one is a white magnolia - blooms in early spring, then the leaves appear another is a red maple of some type third one is a bushy type that comes up each year and spreads by sending out shoots
It might be safer to id the Magnolia when it has flowers. Acers are very difficult to id from pics 3. Looks like Phlox paniculata. http://www.google.co.uk/images?hl=e...=UTF-8&source=og&sa=N&tab=wi&biw=1244&bih=528
Star magnolia or Loebner magnolia. Multiple kinds of each on the market. Redleaf Japanese maple. Even more kinds of these on the market, impossible to have any idea from this far away. Variegated phlox. The green-leaved portions should be dug out and discarded.
