Hound’s tongue is toxic to cattle, deer, pigs, horses, and goats.
About This Species
Hound’s tongue grows on dry, well-drained sites. Each plant can produce 2,000 – 4,000 barbed seeds per year that cling to clothing, livestock, and wildlife. It is considered a noxious weed throughout the province.
How to Identify
One year old Hound’s tongue plants form a rosette with flopping leaves that resemble the shape of a dog’s tongue. In the second year, mature plants develop rough, hairy, wide leaves and red flowers with five petals each. Each flower produces four rounded-triangular seeds covered with hooked prickles.
