Chamaecyparis lawsoniana Columnaris

Lawson's cypress 'Columnaris'

Easy to grow with striking blue foliage

An elegant, narrow, conical conifer growing slowly to 3m (10ft) or more. Flattened upright sprays of blue-grey leaves grow closely together to form a slender cone. The colour is striking throughout the year, especially in summer. A lovely subject against dark evergreens, as a focal point in a planting scheme, or a stand-alone specimen. Good for vertical interest in a small garden where space is limited.


Plant in full sun or semi shade in a bed or border, in gravel or in a large pot or container when young.


Any well-drained, but moist fertile soil. Dislikes extreme drought. No pruning required except the removal of any leaves which spoils the shape.

Lawson cypress was introduced in 1854 when seeds were sent from Oregon and California to P. Lawson and Sons Nursery, Edinburgh

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
