Description More Info Delivery Reviews Video
Achillea 'Cassis' is one of the very best perennials for a mixed border. With its tall, ferny foliage and wonderful flat flower heads made up of tiny dark red blooms, this easy-to-grow Achillea makes a perfect addition to your borders where it will bloom all summer long. Achillea 'Cassis' - as with other Yarrow varieties - loves a hot, sunny border and will add colour to your summer garden whilst requiring minimum maintenance.

The showy flower heads are produced on plentiful stems throughout the season and are incredibly eye-catching - pollinating insects love them! Resilient and low-maintenance, Achillea is ideal for cottage garden borders and wildlife gardens - it will even tolerate coastal gardens. The long stems and unusual flower heads make lovely informal cut flowers for floral displays. Height: 1m (39"). Spread: 50cm (20").

Our garden ready plants are selected for garden performance, straight from the nursery. We send them to you 'green' ahead of flowering (but please note some varieties may show a few blooms), which means plants will establish quickly and all their energy goes into producing better roots, so they produce more flowers throughout the season.

Culinary note: The leaves of the yarrow can be used cooked or raw. They have a bitter flavour but are good in mixed salads and best used when young. They may also be used as a preservative or flavouring for beer. The flowers and leaves can be made into an aromatic tea. click here.

Flowering Months
Stake achillea stems in late spring. Cut back faded achillea flowers to encourage a second flush in late summer. Yarrow plants are relatively short lived perennials that will benefit from regular division every 2 or 3 years to maintain their vigour. Lift and divide overcrowded clumps in spring. Caution: irritant to skin and eyes.
