The blooms are highly attractive to bees.

Tall, upright spikes of pinkish tubular flowers appear from summer to fall. These are highly attractive to bees. Spent flower spikes should...

Named for the mythological Greek god Achilles, whose soldiers supposedly used these plants for healing, Achillea includes approximately 115 species bearing nicknames such as allheal, bloodwort and yarrow. Comprised mostly of deciduous perennials or sub-shrubs, yarrows are found naturally in temperate regions of the Northern Hemisphere, with most species originating from Europe and Asia.

The fern-like foliage of these plants typically forms a mat or mound, or may be held in ground-hugging...

Introduced by Blooms of Bressingham, this pretty, compact yarrow was discovered by Alan H. V. Bloom in 1979, who found it growing among a stand of the popular cultivar 'Moonshine'. ‘Anthea’ forms a dense clump of ferny, silvery-green foliage which is more resistant to disease than that of its parent. Dense, flattened clusters of pale primrose-yellow flowers are borne on upright stems in late spring. They create a vibrant contrast with the cool-toned leaves, and are attractive to butterflies.
