Flowering Months

This clump forming perennial Cornflower bears an abundance of lavender-pink flowers from midsummer, which are irresistible to butterflies and pollinating insects. Commonly known as Bachelor's Buttons, Centaurea dealbata will quickly form dense clumps of large, ornately cut foliage. Plant them en masse and they will knit together to create fabulous swathes of ground cover. This fuss-free perennial is perfect for herbaceous borders, cottage gardens and wildlife areas. Height: 90cm (36"). Spread: 60cm (24").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow

Grow Centaurea in borders in full sun. Knapweed is drought tolerant once established and will happily tolerate almost any soil, except those that are excessively waterlogged.

More Info

Knapweed plants require little maintenance. In autumn, remove the old foliage and faded centaurea flower stems, and apply a mulch of well rotted manure or garden compost around the base of the plant in spring.
