Complete Plant Information
Overview
Nandina domestica ‘Moon Bay’, commonly known as Heavenly bamboo, is prized for its refined, upright structure and year-round ornamental appeal. Gardeners value this broadleaf evergreen shrub for its interesting foliage display that matures throughout the seasons. The cultivar ‘Moon Bay’ offers a compact form, making it versatile for smaller landscape applications compared to its taller relatives.
This rhizomatous shrub provides excellent texture, transitioning from airy spring flowers to persistent, bright berries lasting well into winter. While native to Asia, Heavenly bamboo adapts readily to various conditions, provided it receives at least partial sun for optimal performance. Nandina domestica ‘Moon Bay’ is an excellent choice for adding vertical interest without overwhelming a space.
Established plants demonstrate notable resilience to common garden stresses, making the Heavenly bamboo a rewarding addition for gardeners seeking low-to-medium maintenance impact. Its fine-textured leaves provide a soft contrast to coarser plantings in borders or woodland settings.

How to Grow
Plant Nandina domestica ‘Moon Bay’ in the spring or fall, giving it time to establish before extreme temperatures hit. This shrub thrives in average, medium-moisture, well-drained soils. While it tolerates a wide range of soil types, it prefers soil rich in humus. For vibrant display, site your Nandina domestica ‘Moon Bay’ where it receives full sun or partial shade; too much heavy shade can reduce foliage density.
Watering should be consistent, especially when the plant is young, to establish a robust root system. Mature plants show good drought tolerance, but consistent moisture yields the best results. Fertilizing is rarely necessary if the soil is rich, but a balanced slow-release fertilizer in early spring can encourage vigorous growth.
Pruning is generally light, mainly involving removing any dead or crossing winter-damaged stems in late winter or early spring. In colder sections of its hardiness range (like Zone 6), be prepared for potential winter dieback, treating it almost like a deciduous perennial by cutting stems back severely in spring. For the best fruiting display on Heavenly bamboo, plant several specimens close together.
Landscape Uses
The aesthetic qualities of Nandina domestica ‘Moon Bay’ make it highly adaptable, particularly as a low border plant or mass planting. Its compact size is excellent for use near foundations where taller shrubs might interfere with architecture. Grouping or massing these shrubs creates a cohesive visual effect, highlighting the plant form, foliage, and seasonal color shifts.
Consider utilizing Nandina domestica ‘Moon Bay’ in informal settings, such as naturalized areas or woodland edges, where it complements the surrounding environment without demanding rigid shaping. In warmer zones (8-10), it serves admirably as a low, informal hedge where its evergreen nature remains reliable throughout the winter months. It also functions exceptionally well as a specialized ground cover or an edging element due to its relatively low stature.
