The architectural flower spikes of this herbaceous plant are green and white when in bud, maturing to soft purple and white flowers, which contrast well with the large dark green leaves.

ACHILLEA ptarmica 'Boule de Neige' (The Pearl Group)
This variety of Achillea has a button-like flower shape with double white flowers in mid summer, which contrast well with the dark green finely cut foliage.
In contrast to other Achillea varieties this plant produces individual single white button flowers, which contrast crisply with the dark green foliage.
