About Lawson cypress
Chamaecyparis lawsoniana, commonly known as Lawson Cypress or Port Orford Cedar, is an evergreen conifer from the Cupressaceae family, valued for its elegant conical shape and dense foliage. Its scale-like needles, often in bluish-green or silvery hues, give it a soft texture and a distinctive visual appeal. It is ideal as a specimen plant in gardens, for hedging, or as an ornamental tree in parks, providing structure and color throughout the year.

Care tips
It prefers full sun to partial shade, with protection from strong, dry winds. It requires well-drained, moist but not waterlogged soil, slightly acidic to neutral, and regular watering, especially during dry summers. Ensure the substrate does not dry out completely, but avoid waterlogging which can lead to root rot. A common mistake is planting it in heavy, poorly drained soils, which compromises its health and longevity.
