All parts of hydrangeas are unsafe for pets. Leaves, buds, and flowers contain toxic compounds that may cause vomiting, diarrhea, and lethargy. Contact a veterinarian if plant material is chewed or swallowed.
Hydrangeas are ornamental shrubs with large mophead or lacecap flower clusters in blue, pink, purple, or white.
Common in foundation plantings, garden borders, and cut-flower displays. Potted hydrangeas are sold as gifts and placed on porches and entry areas.
Seasonal pruning leaves stems, leaves, and blossoms in yard-waste piles near compost bins. Mixed bouquets may conceal hydrangea. Dried flower heads may shed small fragments during handling.
