With their colourful, flat-top flowerheads, achilleas make a great addition to ornamental borders.
Achilleas aren’t especially fussy about their planting position, so you can plant them in full sun or partial shade, as long as the soil is well-drained and doesn’t become waterlogged. They combine well, too, suiting a range of styles, including gravel gardens and wildlife gardens.
The small flowers are particularly easy for pollinators to access, and are a favourite flower of hoverflies. Deadhead the spent flowerheads to encourage more of the summer blooms.
Discover some of the best achilleas to grow, below.
Achillea filipendulina ‘Cloth of Gold’
Whereas most other achilleas grown in the garden reach around 60cm in height, Achillea filipendulina can reach 2m tall, so is well-suited to the back of a border. ‘Cloth of Gold’ has deep yellow flowers and is best grown in full sun.
Height x spread: 1.8m x 45cm.
As the name suggests, ‘Paprika’ has red-pink flowers, each of which is dotted with a bright yellow centre. As a cultivar of Achillea millefolium, it’s shorter in stature and look great in the middle of a border.
H x S: 80cm x 60cm.
‘Petra’ has rich ruby-red flowers, each with a creamy-white centre. The colour gently fades as the flowerheads mature. Looks lovely planted with white-flowered plants, including other achilleas.
H x S: 60cm x 50cm.
The burnt-orange blooms of ‘Terracotta’ look gorgeous alongside purple flowers, like the salvias that you can just make out in this shot. As they mature, the colour fades to a mellower shade of orange.
H x S: 80cm x 50cm.
‘The Beacon’ is a bi-coloured variety with deep red flowers that have yellow centres. Here’s it’s growing alongside a froth of silver tansies (Tanacetum niveum).
H x S: 45cm x 25cm.
Achillea ptarmica ‘The Pearl’
‘The Pearl’ is a pretty cultivar of the wild tansy, Achillea ptarmica, with white, double flowers. Planted in generous swathes, the frothy white blooms look fantastic and make beautiful cut flowers.
H x S: 75cm x 60cm.
Dividing your achilleas
In the right spot, achilleas will slowly spread to form a generously sized clump. They can be lifted and divided every three to five years, which revitalise the original clump and produce new plants that can be planted elsewhere.
