The barometer bush was named such because its blossoms pop when it rains. It is a broadleaf evergreen that grows 5 to 8 feet tall and 4 to 6 feet wide in best conditions. The barometer bush thrives in full sun with little maintenance and is extremely tolerant of dry soil. It needs little extra water once established and shouldn't be fertilized. It can be used as a hedge plant or container plant.
Barometer bush is non-toxic to dogs, according to the American Society for the Prevention of Cruelty to Animals. Its leaves, branches, flowers and roots are all safe. Along with dogs, barometer bush is not poisonous to cats or horses.
Barometer bush does have lush leaves and petals that allow dust to collect in them. It's common for congestion to develop when encountering the bushes because of allergens that may be clustered inside. This dust can affect animals, as can any toxic fertilizers or treatments applied to the plants, so opt for organic and pet-friendly products. Barometer bush can also allow snakes, spiders, scorpions, insects or toads that can poison dogs to hide within its leaves.
If you suspect your dog has encountered poisonous material, collect any possible material, plant matter or insects you suspect may be involved and take it with your dog to your veterinarian. If you're unsure, don't hesitate to call your vet -- animals may sometimes appear normal for hours or even days after consuming something toxic.
