Overview of Nandina Growth Habits
Nandina is a versatile shrub that can grow in a variety of conditions. It typically reaches heights of 3 to 8 feet and spreads about 2 to 4 feet wide. Its growth habit is generally upright with a bushy appearance, making it suitable for borders, foundation plantings, or as a focal point in landscape design.
Growth Rate and Seasons
The plant has a moderate growth rate, usually adding 6 to 12 inches annually under optimal conditions. Nandina’s growth cycle is influenced by the seasons:

Growth Habits and Form
Nandina exhibits a clumping growth form with multiple stems arising from the base. It tends to maintain an upright posture but can become more spreading with age or in response to pruning. The plant’s dense foliage provides excellent cover for small birds and wildlife.
Factors Influencing Growth
Several factors affect Nandina’s growth habits, including:
- Sunlight: Prefers full sun to partial shade for optimal growth and coloration.

Practical Tips for Managing Growth
To promote healthy growth and maintain a desirable form, consider the following tips:
- Prune in late winter or early spring before new growth begins.
- Remove dead or damaged stems to improve air circulation.
- Thin out dense areas to prevent overcrowding and encourage light penetration.
