Yew is an evergreen shrub or small tree (Taxus species) with flat dark needles and red berry-like arils, commonly planted as hedges around homes, parks, cemeteries, and office landscapes. Clippings are also used in wreaths and holiday decorations. Most plant parts contain taxine alkaloids.
Leaves, seeds, and twigs are the main toxic parts. Exposure may occur from chewing live plants, fallen trimmings, or decorative arrangements. The red fleshy aril is less toxic, but the hard seed inside is dangerous. Small amounts of plant material may cause severe cardiac effects.
For pets, yew should be treated as strict no-access landscaping. Remove pruning debris promptly and identify holiday greenery before indoor use. Any suspected ingestion requires immediate veterinary evaluation.
Yew branches are often clipped into topiary shapes, and trimmings may be left temporarily on tarps or in open bins. Winter arrangements in entry halls and fireplaces may place needles at nose level indoors. Even brief chewing should be treated as an emergency.
Taxus clippings are sometimes mixed with other hedge waste in municipal yard bags, which can make identification difficult. Pets exploring these piles may ingest needles before owners notice. Bag and remove clippings immediately after pruning.
