Experts are calling attention to a popular landscape shrub commonly known as Heavenly Bamboo.
(Scientific name: Nandina domestica ). https://plants.usda.gov/core/profile?symbol=NADO
This shrub has dark green leaves and bears clusters of vivid red berries which ripen in mid winter.
However, there have been several documented reports of birds eating the berries and dying soon after.
According to the Audubon Society, and other experts, these berries contain chemicals that produce hydrogen cyanide.
