Description How to Grow More Info Delivery

As beautiful in bud as in flower, this native of the Balkans provides a banquet for bees and butterflies. Centaurea atropurpurea forms rosettes of silvery-grey foliage which from early summer bear stout stems topped with beautiful bronze buds, intricately detailed with spiny scales. The buds open to reveal feathery, wine-red flowers and attract a wealth of pollinators. This unusual plant is a perfect choice for informal borders and wildlife gardens, drought prone areas or coastal positions. Flowering commences in June and will continue for many weeks if dead-headed. The tall stems add height to borders and make excellent material for cutting.

Height x Spread: 90cm to 120cm (36in to 47in) x 50cm (20 in).

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.
