Summer Wildflowers: Dogbane
Dogbane is an important plant to be able to identify - as its name suggests, this plant is notable for its toxicity to humans and other animals, including dogs.
Spreading dogbane (Apocynum androsaemifolium) is most easily identified by its opposite, oval-like pinnate leaves; it has bell-like white petals with red or pink veins. I often observe dogbane with a reddish stem, but I wouldn’t suggest basing your identification of that trait.
Dogbane is found on slopes and hillsides or open conifer woods from June to September. Watch out for this plant, as its poisonous, milky white sap is toxic - if you suspect your dog has ingested dogbane, contact a veterinarian immediately.
