Common questions

Are the red flowers safe if my cat chews them?

Yes — the brush flowers are as non-toxic as the leaves. They also attract bees, so the sting risk from pouncing cats is the real-world hazard.

Is bottlebrush safe for birds and other pets too?

It is widely regarded as pet-safe across cats, dogs and birds, which is why it is a staple of animal-friendly garden lists.
