General Culture:
Easily grown in average, medium, well-drained soil in full sun. Freely self-seeds. Prompt removal of spent flowers will prevent unwanted self-seeding.
Noteworthy Characteristics:
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.
Problems:
No serious insect or disease problems. Taller plants may need staking or other support.
Uses:
Borders, herb or vegetable gardens.
