Like our farm, Highland Hill Farm, Solebury Township Pa. is
located in an area with lots of clay. We therefore like plants
that grow well in clay. Arborvitae, in particular the American
Arborvitae is one of our favorites. Here is why. The hardiness
zone for the American Arborvitae is from zones 5 to 8. Its
evergreen with rapid growth rates that in ideal conditions can
be up to 1.5 feet per year. Site requirements for the American
Arborvitae is sun to partial shade, moist well drained soil but
does well in clay, and needs protection from wind . Its texture
is fine with its form conical being narrow to broadly pyramidal,
reaching from 30 to 40' in height to 6 to 12 feet in width. The
leaf is green graceful foliage. It keeps its foliage color in
the winter but can tend to bronze alittle in the winter. The
American Arborvitae flowers/fruit are .5" erect female cones.
The American Arborvitae has strong wood, casts dense shade, and
has red bark when young. Arborvitae do not tolerate salt spray.
These arborvitae should outlive even your children.
