About

Perovskia 'Blue Spire' is a named cultivar placed in the mint family, Lamiaceae, and treated within the genus Salvia. It is valued for its long, summer flowering run, producing blooms from June to September. The cultivar is distinctively grown for its summer display rather than for foliage or winter structure. It sits comfortably within Salvia collections and perennial borders where extended flowering is wanted.

In the garden

Perovskia 'Blue Spire' is a cultivar represented within the family Lamiaceae and classified under the genus Salvia. As a named selection, it is grown specifically for its flowering season and is handled like other ornamental Salvias in planting schemes. Gardeners choose cultivars such as this when a reliable summer sequence of flowers is required. Flowers appear across the summer months, with an authoritative UK flowering period from June to September; that run defines how the plant is used in planting plans. Sit it where its flowering period will be most noticed—along mixed borders, beside summer-flowering perennials, or in runs for seasonal impact—so the blooms contribute when many spring bulbs and early perennials have finished. Because this is a Salvia cultivar, it is usually managed as part of summer-focused planting schemes rather than as a structural winter element. Where repeated seasonal colour is the priority, Perovskia 'Blue Spire' provides a sustained window of bloom. Expect its main ornamental contribution to be its June to September flowering display, which is the defining horticultural feature of this selection.
