bachelor's button
A striking twist on a cottage garden favourite, Centaurea 'Amethyst in Snow', also known as bachelor's button or perennial cornflower, is anything but ordinary. Its unique two-tone flowers feature a deep amethyst-purple centre surrounded by a delicate halo of crisp white petals, making it a real head-turner in any border. Blooming from late spring into summer, Centaurea 'Amethyst in Snow' provides a long-lasting display that not only brightens the garden but also attracts bees and butterflies in droves. The grey-green foliage forms a neat, clump-forming base, adding texture and interest even when the blooms take a break.
Drought-tolerant and easy to grow, Centaurea 'Amethyst in Snow' thrives in well-drained soil and full sun, making it perfect for low-maintenance borders, wildlife gardens, or even rockeries. Its flowers make wonderful cut specimens, adding a touch of wild charm to indoor arrangements. Once the blooms fade, the seed heads bring a rustic appeal, ensuring this perennial earns its place in the garden year-round. Undemanding yet highly rewarding, Centaurea 'Amethyst in Snow' is a true gem for gardeners who love a plant with both character and resilience. Also known botanically as Centaurea montana 'Amethyst in Snow', it’s a plant that brings both contrast and charm to any planting scheme.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
