In the garden

Stachys macrantha 'Superba' or 'Robusta' is a perennial member of the Stachys group, native to the Caucasus, northeastern Turkey and northwestern Iran. Its native range indicates a tolerance for continental summers, which translates into reliable flowering during the British summer when given the right position. Place this perennial where it receives full sun or at least partial shade and where the soil drains freely while retaining some moisture. Work organic matter into heavier soils to improve structure and moisture-holding capacity without causing waterlogging. Mulching the root area helps moderate moisture levels over the growing season. The cultivar is rated H5, meaning it is hardy and suitable for outdoor planting across most UK gardens without winter protection. Use Stachys macrantha 'Superba' or 'Robusta' in front to mid-border planting or to form a low ground cover beneath taller perennials and shrubs. It complements other summer-flowering perennials and fills gaps with sustained bloom. Expect consistent flowering from June to September once plants are established, providing a lengthy season of interest through the summer months.
