A tall perennial with distinctive dark red or burgundy bottlebrush-like flower spikes that bloom mid- to late summer. It thrives in moist conditions and is valued by pollinators and for cut flowers.

Why grow it

Great burnet produces distinctive burgundy flower spikes that persist longer into late summer than many other meadow perennials, making it useful for extending seasonal interest in moist-site plantings. Unlike some ornamental burnet varieties bred primarily for foliage, this species is equally valued by native pollinators and performs reliably in both garden and semi-wild settings. It tolerates the poorly drained conditions that exclude many alternatives and requires minimal intervention once established in appropriate moisture zones.

Watch out for

Great burnet prefers consistently moist soil and may struggle in drought conditions without supplemental watering. While adaptable to part shade, it produces the most robust flowering in full sun to part sun locations. Division every few years helps maintain vigor and prevents overcrowding in established plantings.
