Bring on Spring

As I was exploring in the nearby fields I came across what I think may be sand plum trees.  I want to remember that in the summer when they will be covered with plums...that is, if I am correct about the identification in the dead of winter.  I had a great idea, "Why not bring a small branch or two with buds on it, stick it in some water and see if it blossoms with plum flowers. "  Any day now I will know.  In the mean time my cuttings from my apple trees and plum trees in the back yard have already started to give me some hope of spring.
