Chamaecyparis obtusa 'Split Rock'
Rock Chamaecyparis is a beautiful, and very interesting variety of
Dwarf Hinoki ( obtusa ) Cypress. It is rather slow growing, and is the only Hinoki
with a bluish colored foliage at all. Growth habit is rather pyramidal as the plant matures, but often starts out with a slightly more rounded shape when very young. One of the main distinguishing feature of this variety that sets it apart from most other Chamaecyparis is the fact that it actually has two different foliage types on the same plant - with two different foliage colors as well. This plant possesses both flattened sprays of adult type foliage that has a nice green color........along with equal amounts of juvenile foliage which is a very attractive shade of blue / green. The two different foliage types mixed together throughout the entire plant make for a very interesting contrast of color and texture.
Uses include specimen plantings, also makes a nice colorful accent for semi shaded areas - even makes a great candidate for container gardening too!! This variety has to be one of the most unusual types that we grow. But we only have a few available each season, so they are not always easy to get.
