Great burnet Similar Species

Salad Burnet, Sanguisorba minor, is a much shorter and altogether less spectacular wildflower; it grows in dry calcacareous grassland but has long been cultivated as a kitchen herb for its mild-tasting leaves. Less attractive to insects than its larger, brighter close relative, Salad Burnet relies mainly on the wind to distribute its pollen.

The specimens shown on this page were photographed in East Anglia in summer.
