Microbiota decussata, commonly known as Siberian Cypress, is an evergreen shrub native to the mountainous regions of the Russian Far East, particularly the Sikhote-Alin range. It is a low-growing, prostrate shrub reaching 20–50 cm (8–20 in) in height and spreading 2–5 m (6.6–16.4 ft) wide. Its foliage, which forms flat sprays, consists of scale-like leaves 2–4 mm long. The plant produces very small cones, 2–3 mm long, which are among the smallest of any conifer, maturing from green to brown in about 8 months after pollination. Each cone typically contains one seed, occasionally two, which are 2 mm long and wingless. In winter, the foliage may turn brown, mimicking dormancy, but it rejuvenates come spring.

Siberian Cypress is appreciated for its ground-covering habit, making it a suitable choice for gardens and parks. It is particularly valued for its drought tolerance and ability to withstand cold temperatures and winter conditions. It has earned the Royal Horticultural Society’s Award of Garden Merit, signifying its excellence for garden use. Siberian Cypress is best cultivated in full sun to part shade, requiring medium water and well-drained soils. It is often used for erosion control on slopes due to its spreading nature and is also planted in rock gardens for its textural interest.CC BY-SA 4.0
