Achillea.

This is one of the many flowers I've wanted in our Garden. I bought it today.
I have a long list of them, so this is one I can cross off my list.
The flower heads are long lasting and attract Hoverfly's and other beneficial insects, but surprisingly unattractive to Bee's.

The scientific name Achillea is for the Greek mythological character Achilles. According to the Iliad, Achilles' soldiers used yarrow to treat wounds hence the common names "All Heal" and "Bloodwort". The specific name, millefolium, literally names "thousand leaf" referring to the fern-like divided leaves.
