Achillea clavennae, the silvery yarrow, is a herbaceous perennial flowering plant in the sunflower family. The species name (clavennae) honors the Italian botanist N. Clavena (17th century).
Silvery yarrow has strong disease resistance and is generally not prone to illnesses. However, it can be affected by pests and diseases present in its surroundings. These infections are typically not severe. For care, this plant needs moderate maintenance. It should be pruned regularly to maintain a tidy appearance and encourage healthy growth. Fertilizing can also help promote flowering. Silvery yarrow is suitable for anyone with outdoor space, such as a garden or patio, and does not require extensive plant-care experience. It may demand more attention when grown indoors.
How to keep Achillea Clavennae.
Light
Silvery yarrow is a sun-loving, perennial herbaceous plant native to open habitats and commonly found in meadows and grasslands. It prefers full sun but can tolerate partial sun.
Water
Silvery yarrow is native to well-drained environments, where it thrives with moderate moisture and can tolerate short periods of dryness. To keep it healthy, it needs to be watered once a week, although it also adapts well to seasonal rainfall. This makes it an excellent choice for gardens in temperate climates.
Fertilizer
The best time to fertilize a Silvery yarrow is in early spring, as it comes out of dormancy and begins active growth. Fertilization supplies essential nutrients needed for healthy growth. While Silvery yarrow has relatively low fertilizer requirements, applying fertilizer annually can improve its survival and encourage better, longer-lasting flowers.
Pruning
Silvery yarrow has distinctive silvery leaves and thrives with annual pruning from early to late spring. Begin by removing dead stems and thinning the plant to enhance air circulation. After the plant flowers, a light trim encourages growth and more blooms. Consistent care helps minimize issues with mildew and pests.
