Japanese Yew

Lawn & Garden

The Japanese yew is a type of shade-tolerant conifer that produces bright berries. Unlike most conifers, yews can thrive in areas with less sunlight. Their dark green needles add a touch of color to shady gardens throughout fall and early spring.

The original Japanese yew is a tree with a single trunk that can grow up to 50 feet tall. However, most cultivars are dwarf varieties that can be globular, vase-shaped, pyramidal, or spreading, depending on the selection. Despite being labeled as dwarf plants, most eventually grow up to 20 feet or more. The needles of Japanese yews are dark green and have rounded tips, and unlike other conifers, they are not scratchy. Female plants bear bright red berries. Japanese yews are easy to care for.

Japanese yews are tolerant of moderate shade, and even deep shade, as long as they receive some spring sunlight. In dense shade, shrubs may need harsher pruning to help fill in gaps formed by a more open growth pattern. Yews require fertile soil and ample moisture and cannot tolerate root competition from shallow-rooted trees. They should also be protected from strong, drying winds.

Japanese yews are propagated by cuttings, usually carried out by professionals, or seed. They are widely used as foundation plants, especially on the north or east sides of homes. They make excellent formal or natural hedges, and dwarf varieties are popularly used in rock gardens.

Taxus baccata (English yew) and T. x media (hybrid yew) are related species to the Japanese yew, although the English yew is less hardy (USDA zone 6). The scientific name of Japanese yew is Taxus cuspidata.

If you don’t have an outdoor garden but love the Japanese yew’s berries, consider growing it as a houseplant. Learn more about gardening and great plants you can grow, such as shade gardens, shade garden plants, garden types, and gardening.

Japanese Yew can be propagated by seed or cuttings. Seeds can be collected in the fall and planted in a well-drained soil mix. However, seed propagation can be slow and unpredictable. Cuttings, on the other hand, are more reliable and can be taken in late summer or early fall. Dip the cuttings in rooting hormone and plant in a well-drained soil mix. Keep the soil moist and the cutting in a shaded area until roots develop.
