Perennials
Achillea millefolium 'Alabaster'
Alabaster Yarrow
Achillea millefolium 'Alabaster' is a charming perennial that showcases clusters of creamy white to soft pink, flat-topped flowers that bloom from early summer to late summer. The delicate blooms are held on sturdy stems above feathery, silver-green foliage, creating a soft, elegant contrast. The long-lasting flowers attract butterflies and pollinators, adding movement and life to garden spaces.
Originating from selective breeding to enhance both color and bloom duration, 'Alabaster' is ideal for cottage gardens, wildflower meadows, and borders.

Design tip
The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
