The Story

Plant Bio

Nandina domestica, commonly called heavenly bamboo, is a broadleaf evergreen shrub prized for its lacy, compound leaves and multi-season interest. New growth is often colorful, and it produces panicles of white flowers followed by red berries on many varieties. 'Seika' (Obsession) is a compact, dense cultivar distinguished by its brilliant, fiery red new foliage that persists through spring and summer, contrasting with the mature green leaves. It is a non-invasive selection that rarely flowers or fruits.

Bloom Period:

EarlyLate

Uses & Benefits:

The primary ornamental feature is its stunning, fiery red new growth that provides a splash of vibrant color from spring through fall. Its compact size and fine-textured foliage make it a versatile element in garden design.

Its dense, mounding habit makes it an excellent choice for low-maintenance foundation plantings, mass plantings, or as a low, informal hedge. It is also well-suited for container gardening on patios and balconies.

As a sterile or near-sterile cultivar, 'Seika' does not produce the berries that have led to the species being considered invasive in some parts of the southeastern U.S., making it an environmentally responsible choice.

Planting

How to Grow

Select a site with well-drained soil and full to part sun.
Dig a hole twice as wide as the container.
Amend heavy clay soil with compost to improve drainage.
Set the plant in the hole with the root crown at soil level.
Backfill the hole and water deeply to settle the soil.
Mulch around the base to conserve moisture and suppress weeds.

Pro Tip

For the most intense red foliage color, plant 'Seika' in a location that receives at least six hours of direct sunlight daily.

Keep It Thriving

Care Guide

Do

Water regularly during the first year to establish a deep root system.
Provide acidic to neutral soil for best performance.
Prune out the oldest canes at the base to encourage fresh, colorful growth.
Monitor for chlorosis (yellow leaves) and treat with an iron supplement if needed.

Don't

Do not plant in poorly drained or constantly wet soil.
Avoid alkaline soils, which can cause nutrient deficiencies.
Do not shear the plant like a formal hedge; it ruins the natural form.
Avoid planting the species form, which can be invasive in some regions.
