Is Bottlebrush Toxic to Dogs and Cats? (2026)

No treatment is needed for Bottlebrush specifically. Don't extend that same reassurance to other myrtle-family plants like eucalyptus without checking them individually.

Bottlebrush is not known to contain toxic compounds harmful to dogs, cats, or horses.

Bottlebrush is confirmed non-toxic to dogs and cats by the ASPCA. Its distinctive red, bristly flower spikes — shaped like the brush used to clean a bottle — are a magnet for hummingbirds and bees. It's in the myrtle family, the same family as eucalyptus, which is a useful reminder that family alone doesn't determine toxicity: eucalyptus itself is toxic to pets even though this relative isn't.
