About the genus
Sanguisorba is a genus of flowering plants in the family Rosaceae native to the temperate regions of the Northern Hemisphere. The common name is burnet.
In the garden
Poterium belongs to the Rosaceae family and is treated as a distinct genus within that group. In the UK its flowering season runs from June to August, a useful detail when planning summer display or succession planting. When selecting Poterium plants, pay attention to the species name on the label and any cultural notes provided by the nursery; requirements can vary between species within a genus. Inspect the rootball or crown for sound tissue and avoid plants showing mould or severe dieback. Growing success depends on matching the chosen species to a site and soil indicated by the supplier rather than assuming uniform needs across the whole genus. In garden design, plan for Poterium where a summer-flowering contribution is wanted and place it alongside plants with complementary flowering times. For maintenance, follow the species-specific guidance given at purchase and monitor flowering through the June-to-August period to assess whether the chosen site suits that particular plant.
