In the garden
Sanguisorba off. 'Red Thunder' sits in the genus Sanguisorba within the Rosaceae and traces its lineage to temperate parts of the Northern Hemisphere. Plants form a central crown of pinnate leaves — often 5–30 cm long with multiple serrated leaflets — and send up erect stems that carry dense, 5–20 mm flowerheads. Individual flowers are very small, with four petals that can range from white to red, and flowering runs from June to August. Choose a position where the tall stems can be seen and appreciated; the species' habit suits sites that offer some vertical space rather than tight, low-growing borders. Aim for soil that retains moisture without remaining waterlogged and a situation that receives good light through much of the day. Established crowns can be divided in spring to renew vigour and to create additional plants. In UK planting schemes this cultivar works where upright, long-stemmed summer flowers are wanted — between grasses, at the back of mixed perennial borders, or in informal, naturalistic drifts. Expect the small clustered flowerheads to be carried well above the foliage from June to August, providing seasonally reliable structure.
