Achillea is a group of flowering plants in the family Asteraceae described as a genus by Linnaeus in 1753.
The genus is native primarily to Europe, temperate areas of Asia, and North America.
The common name “yarrow” is usually applied to Achillea millefolium, but may also be used for other species within the genus.
These plants typically have frilly, hairy, aromatic leaves.
The plants show large, flat clusters of small flowers at the top of the stem.
The flowers can be white, yellow, orange, pink or red and are generally visited by many insects, and are thus characterized by a generalized pollination system. (source wikipedia)
So can rabbits eat achilea?
Unfortunately it is not good for them at all and may make them sick if consumed.
