Description
Achillea ptarmica ‘Diadem,’ or ‘Diadem Yarrow,’ is a tough, compact perennial that’s perfect for any garden. Growing in a neat, rounded shape about 30-35 cm tall, it stands out with its finely textured leaves and clusters of double, white, pompom-like flowers.
Unlike most yarrow, which has flat flower heads, ‘Diadem’ features charming, rounded blooms that give it a unique look.
Bred by Dutch breeder Janus Verschoor, this plant works well in flower beds, borders, or containers, adding structure and a soft contrast to brighter summer flowers. It thrives in both sun and partial shade and handles a range of weather conditions with ease.
To keep it blooming longer, trim back the spent flowers regularly. This low-maintenance plant is a great way to bring texture and subtle beauty to your garden.
