Nandina domestica (Non-native)

Notes: Nandina is found in most landscaping mixes in yards, parks, hospital grounds, and other locations in the lower 48 states. Its bright red berries and contrasting dark green foliage add color and texture to landscapes. 

Nandina berries last for months, attracting hungry birds when food is in short supply Studies show planting Nandina harms birds. Nandina berries contain cyanide and other alkaloids that produce highly toxic hydrogen cyanide (HCN) which is extremely poisonous to all animals. Sudden death may be the only sign of cyanide poisoning and death usually comes in minutes to an hour.
