Chamaecyparis lawsoniana 'Ellwoodii' (Lawson's cypress 'Ellwoodii')

Lawson Falsecypress is an evergreen native to the northwestern United States. It has flat, dark blue-green leaves with a delicate appearance. It is suited to large landscapes, and it is ideal as a screen. If planted in clay soils, it is susceptible to a fungal infection causing root-rot, which is fatal to the tree. This tree comes in several hundred different cultivars, with differing foliage colors and growth types .
