Common Yarrow (Achillea millefolium 'Alba') - Description
Achilleas are one of the most versatile and easy to care perennials you can grow. They are cherished for their colorful, flat-topped blooms as well as their lacy, silvery, gray-green foliage. Yarrows are all-time favorites for the sunny border. Flowers are produced over a long season of bloom, June through September. Start indoors 8 weeks before last frost. Tolerant of dry soils, this Achillea grows 2-3 ft. tall and should be spaced a similar distance apart. Well suited for the vase, and outstanding as dried cuts, with stiff stems and persistent color. They also attract butterflies.
Common Yarrow (Achillea millefolium 'Alba') - Blooming
Blooms generously through summer and early fall and are promoted by frequent deadheading. Taller species can be used for drying for Winter bouquets. Flower colors are generally yellow or white, but some species are pink and red. If flowers are cut off, the plant will regenerate flowers in about a month.
Common Yarrow (Achillea millefolium 'Alba') - Growth
Yarrows germinate in 3 to 5 days, and the stem and cotyledons appear between days 5 and 7. Leaves are generally green/gray and have an aromatic smell especially when the leaves are crushed.
Common Yarrow (Achillea millefolium 'Alba') - Planting
Can be grown from cuttings or seeds. Either way, plant in a disease-free medium with uniform moisture. Keep the pH between 5.5 and 5.8. Add a layer of vermiculite to aid in moisture retention.

Common Yarrow (Achillea millefolium 'Alba') - Interesting facts
Yarrows are native to Europe and temperate areas of Asia. Achillea was first recorded in 1753 by Carl Linnaeus, a Swiss botanist and physician, who was the father of the binomial nomenclature, which is the formal system of naming specific species. Yarrows are relatively easy to grow, requiring only routine maintenance and can thrive even in poor soil/watering conditions. They are great in the garden or as cut flowers or even dried for winter arrangements.
Common Yarrow (Achillea millefolium 'Alba') - Soil and irrigation
Once established, yarrows can withstand drought. However, ideally the medium should receive moderate irrigation and even moisture distribution throughout the soil. This is especially important while inducing germination.
