Plant Profile: Cornus alba 'Argenteo-marginata'

The Variegated Tartarian Dogwood is a sizable shrub known for its striking variegated leaves. With proper pruning, it can be shaped into a small tree. This plant thrives in well-drained soil and prefers full sun to partial shade, although it can adapt to various soil types. It typically grows upright but may develop a more arching form as it matures, featuring long, unbranched stems that can produce suckers, leading to the formation of extensive colonies.

To maintain its vibrant color, it is advisable to remove the oldest stems, as the most vivid hues are found on new growth. Since it spreads through its roots, occasional root trimming may be required.

This shrub is best showcased in groups or mass plantings, particularly in naturalistic settings with moist soil where it can spread and create thickets. It serves well as a screen along property lines, in hedges, or as part of shrub borders. Additionally, positioning these shrubs as focal points in areas where their colorful stems can be admired enhances their ornamental value.
