Elder shrub.

This is actually considered a shrub not a tree. We have been pruning about 18 inches off of it every spring except the last two years. This gives lots of privacy in our little back yard. There is always a sparrow in it since the bird bath is a hop from it. When it is finished blooming it will form a red cluster of berries which are supposed to be edible. The birds will come in the winter and clean up every berry.
I have found that it resents being transplanted after about 1 foot in height. I have killed many by doing so. I have also lost a few when we get a sudden temperature drop in the winter. Click on image for a closer look.
