Chamaecyparis lawsoniana 'Ivonne' | Rating: 0 votes | Print / Pdf

Chamaecyparis lawsoniana is a type of cypress tree native to the USA that was first discovered in 1854. It's a large tree, growing up to 200ft in height, so is not suitable for most ordinary sized gardens. The trunk can grow up to six feet wide. It's an evergreen conifer, the foliage grows in flat feathery looking sprays, a bluey green colour with small blue/green spherical cones. The wood from this tree is very strong and has a scent of ginger. A lot of it is shipped to Japan where it is used to make coffins and shrines. It prefers a moist soil with good drainage. Root disease is a real problem with this species in the wild.
