WaterFor Noble Yarrow (Achillea nobilis subsp. neilreichii), watering should be done carefully to maintain moderate soil moisture without causing waterlogged conditions. During the active growing season, water the plant deeply once a week, ensuring that about 1 to 1.5 gallons of water per square yard is applied. Reduce watering frequency in the fall and winter when plant growth slows down. If the weather is particularly hot or dry, monitor the soil and water additionally if the top inch becomes dry. Always water at the base of the plant to avoid wetting the foliage which can promote disease.
LightNoble Yarrow thrives best in full sun conditions, which means it requires at least 6 hours of direct sunlight per day. The ideal spot for planting Noble Yarrow would be in an area where it can enjoy uninterrupted sunlight throughout the day. While the plant can tolerate some light shade, too much shade can result in weakened growth and fewer blooms.
TemperatureNoble Yarrow is hardy and can tolerate a wide range of temperatures but performs best in conditions between 65 and 75 degrees Fahrenheit. It can survive short periods of cold down to around 5 degrees Fahrenheit, but prolonged exposure to temperatures below 10 degrees Fahrenheit may harm the plant. During hot summers, temperatures above 90 degrees Fahrenheit are typically well-tolerated, especially if the plant is well-watered.
PruningPrune Noble Yarrow to maintain its shape, remove spent flowers, and encourage further blooming. Deadheading, or cutting off the faded flowers, should be done regularly throughout the blooming season. At the end of the flowering season, usually in late fall, cut back the foliage to a few inches above the ground to help maintain the plant's vigor. Pruning is also an opportunity to remove any damaged or diseased stems.

Life cycleAchillea nobilis subsp. neilreichii, commonly known as Noble Yarrow, begins its life cycle when its seeds germinate, typically in early spring, given adequate moisture and light conditions. The seedlings establish a rosette of leaves at the soil surface as they enter the vegetative stage, a period of growth and development where they accumulate resources. As the plant matures, it develops a sturdy stem and foliage, and eventually, it enters the flowering stage, usually in late spring or early summer, where it produces clusters of small, white or cream-colored flowers that attract pollinators. After pollination, these flowers give way to seeds during the reproductive stage, which, when mature, are dispersed by wind, water, or other means. The Noble Yarrow is a perennial herb, therefore it can survive through multiple seasons with the above-ground portions dying back in the winter and regrowing the following spring from the rootstock. Some plants may also reproduce asexually through rhizomes, contributing to the spread and persistence of the species in its habitat.
PropogationPropogation time
Spring-early summer
Propogation: Achillea nobilis subsp. neilreichii, commonly known as Noble Yarrow, can be propagated most popularly by seed. The best time to sow the seeds is in spring or early summer. The propagation process by seeds involves scattering them on the surface of a well-draining seed starting mix and lightly pressing them into the soil, as they require light to germinate. Noble Yarrow seeds typically germinate within two to three weeks when kept at a temperature around 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Once the seedlings have grown large enough to handle and a stable outdoor temperature is established, they can be transplanted to their desired location in the garden.
