About

Achillea millefolium 'Sassy Summer Sunset' is a vigorous perennial that reaches a height of approximately 80 cm. Its finely divided, grey-green leaves create a dense ground cover before blooming begins. From summer into autumn, the plant produces upright, branching stems adorned with broad, flat clusters of vivid orange flowers, each featuring a yellow center.
