Chamaecyparis lawsoniana Allumii

Common Name: Allumii Lawson Cypress

Description:
The Allumii Lawson Cypress (Chamaecyparis lawsoniana 'Allumii') is an elegant, evergreen conifer known for its dense, columnar growth and striking blue-green foliage. This medium-sized tree has a naturally symmetrical, upright habit, making it ideal for hedging, screening, or as a feature tree in formal gardens. Its soft, feathery foliage provides year-round colour and texture, while its compact nature makes it a popular choice for structured landscapes. Thriving in well-drained soil, it prefers full sun to part shade and is both drought and frost-tolerant once established. With its strong vertical presence and low-maintenance requirements, the Allumii Lawson Cypress is a perfect addition to any garden requiring an architectural element or privacy screen.
