Thanks Oscar, and LG!
Alex, we also want to plants evergreens for a privacy screen, my DH loves arborvitaes.
I also want to plant various, smaller sized evergreens throughout the garden, to add color and different kinds of foliage textures for points of interest. It is amazing how many colors of green there are!
I also have the Golden Chain tree (Watererii) on my list, after seeing it in the Garden Answer videos. It would get planted at the back of the property. The Austrian pine is beautiful, but gets huge!
Further, some flowering trees, such as the cherries, ( we've always grown Kwanzans), crabapples, dogwoods, and plums would be wonderful..
LG, the idea of color themed beds is wonderful!
My ultimate goal this year, besides getting all of my current plants into the ground, is to find a tri-color beech tree. The leaves are spectacular!
