What is the scientific name for Western Red Cedar?

The scientific name for Western Red Cedar is Thuja plicata. This species is native to the Pacific Northwest and is well-regarded for its aromatic wood and durability, making it a popular choice for construction, landscaping, and various crafts. Thuja is a genus of coniferous trees in the cypress family, and plicata refers to the tree's flattened foliage and distinctive scale-like leaves.

The other options represent different species:

• Tsuga heterophylla is the scientific name for Western Hemlock, a tree that is also native to the Pacific Northwest but is not the same species as Western Red Cedar.

• Sequoiadendron giganteum, commonly known as the Giant Sequoia, is a different genus entirely, known for its enormous size and ability to live for thousands of years, found primarily in California.

• Pseudotsuga menziesii refers to Douglas Fir, which is a different species altogether and is also prevalent in the Pacific Northwest.

Recognizing specific scientific names, particularly within a regional context, is essential for horticulturists, as it ensures accurate identification and understanding of plant characteristics and ecosystem roles.
