Achillea (Achillea hybrids) - Description

Medium to large perennial, usually 2' to 3' tall and similar width, as they can be the shape of an upright clump, radiating or sprawling clump. These plants have large, flat clusters of small flowers at the top of the stem. These flowers can be white, yellow, orange, pink or red. A number of species are popular garden plants because they are easy to care for and bloom repeatedly through the summer. A few grow in North America. These plants typically have frilly, hairy, aromatic green or grayish leaves that can be toothed or smooth edged.

Achillea (Achillea hybrids) - 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.

Achillea (Achillea hybrids) - 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.

Achillea (Achillea hybrids) - 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.

Achillea (Achillea hybrids) - Pest

Spittlebugs, aphids and scale can become problems. Also watch out for powdery mildew on the foliage, yarrow leaf rot and root rot.

Achillea (Achillea hybrids) - 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.

Achillea (Achillea hybrids) - 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.
