The Story

Plant Bio

Cryptomeria japonica, or Japanese Cedar, is a large, evergreen coniferous tree native to Japan. It features reddish-brown bark that peels in vertical strips, and soft, awl-shaped needles arranged spirally on the branchlets.

The 'Ikari' cultivar is a unique, irregular upright form noted for its bright green foliage and distinctive fasciated (crested) branching, which resembles an anchor at the tips. This contorted growth habit makes it a striking architectural specimen.

Uses & Benefits:

Provides year-round greenery with a dense, compact form suitable for privacy screens and ornamental focal points.

Drought-tolerant once established, requiring minimal watering.

Supports local wildlife by offering shelter and nesting sites.
