In 1804, Americans introduced "sacred bamboo" as a garden ornament; it spread across an estimated 22,400 forest acres, and its berries have been linked to bird deaths

Sacred bamboo, a popular ornamental shrub, has spread extensively into southern forests across America. Birds consuming its berries are vulnerable to cyanide poisoning, especially cedar waxwings. Unripe green berries contain the highest cyanide levels, posing a significant threat to avian populations. This invasive plant displaces native species, impacting wildlife food and shelter sources. Gardeners are advised to choose less problematic alternatives for sustainable landscaping.
