Boxwood (Buxus sempervirens) is a decorative evergreen shrub or small tree. The plant is frequently used for landscaping, gardens, and holiday decorations (such as wreaths and garland). All parts of the boxwood plant are poisonous to humans and animals, including poultry. They contain steroidal alkaloids. If the leaves are eaten, they can cause convulsions and respiratory failure.
If eaten by poultry, contact your local veterinarian, as your bird may require sedatives and respiratory or heart stimulants to recover from boxwood poisoning.
