Achillea tomentosa aka Yellow Milfoil
Taxonomy
Achillea tomentosa, commonly known as woolly yarrow, is a low-growing flowering plant in the Asteraceae family. Its yellow flowers bloom in dense clusters from spring into summer. While it is sometimes kept as a garden plant, it is originally native to dry lowland habitats of southern Europe and (possibly) western Asia. It may occasionally naturalize outside of its original range. The plant is a recipient of the RHS's Award of Garden Merit. However, it should be noted that woolly yarrow is not tolerant of heat and humidity and may deteriorate in these conditions. It is often used as a groundcover.

Difficulty
Yellow Milfoil is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.
Water
Yellow Milfoil should be watered regularly, allowing the soil to dry out between waterings.
Soil
Yellow Milfoil loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Yellow Milfoil prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Dormancy
During the cold period, it is common for Yellow Milfoil to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
Toxicity
Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.
Fertilizer
The growth of Yellow Milfoil is gradual and it doesn't necessitate any additional fertilizers. Replacing the soil in its pot once a year should suffice to provide the plant with sufficient nutrition. It's important to keep in mind that plants derive their energy from the sun's rays, not fertilizers.
