Great burnet is a clump-forming, rhizomatous perennial which typically grows to 3' tall. Features compound odd-pinnate, medium green, basal leaves (7-25 serrate leaflets each) and small terminal spikes (to 1.5" long) of dark purple flowers in summer. Stems are sometimes tinged with red. Has ornamental value, but is often grown as a culinary herb: leaves (especially younger ones) are excellent in salads and soups.
No serious insect or disease problems. Taller plants may need staking or other support.
