Microbiota decussata (Siberian Cypress) is a low-growing, prostrate evergreen conifer that forms a soft, feathery mat of bright green, scale-like foliage. As temperatures cool, the foliage can shift to bronze and purple tones, giving your planting areas year-round texture and winter interest without demanding constant attention.
You can use Siberian Cypress as a broad, spreading ground cover where you want a neat, conifer look at a low height. It typically stays around 10-12 inches tall and gradually expands outward, making it useful on slopes, banks, rock gardens, and border edges where a cascading, layered effect looks natural.
Plant it in full sun to partial shade. In warmer climates, some afternoon shade helps it look its best, and it generally performs better where summers are not excessively hot and humid. Give it moist, well-drained soil for establishment, then maintain even moisture during extended dry spells. Avoid sites that stay wet or poorly drained, as prolonged sogginess can lead to decline.
Space plants with their eventual spread in mind, and mulch lightly to keep soil conditions steady. Once established, you will find it needs little pruning, aside from occasional shaping or removing stray tips to keep the outline tidy. With good drainage and reasonable summer conditions, Microbiota decussata becomes a reliable, easy-care evergreen carpet that adds fine texture around shrubs and perennials.
