Q: Is Heavenly Bamboo invasive in California?
A: While not officially listed as invasive in California, the species Nandina domestica is a prolific seeder and can naturalize in ideal, moist conditions. In the Bay Area's drier climate, it is generally considered low risk but should be planted with care. To prevent spread, consider sterile cultivars (like 'Firepower' or 'Gulf Stream') or prune off flower clusters before berries form.
Q: Are the berries toxic to birds?
A: Yes, the berries contain cyanogenic glycosides and can be toxic, especially to cedar waxwings if consumed in large quantities. If you are concerned about wildlife, choosing a sterile, non-berry-producing cultivar is recommended.
Q: How should I prune it to keep it looking its best?
A: For a natural look, use the "one-third" method: each year, prune out the oldest one-third of the canes at ground level in late winter. This encourages new, colorful growth from the base, prevents a leggy appearance, and helps control overall size and berry production.
