Overview

Raised in Argentina (its name means 'friendship'), this vigorous, upright sage produces a remarkable non-stop display of large, velvety, deep purple tubular flowers set in dark, almost black calyces, from early summer until the first frosts. Bees and butterflies visit constantly, and in the Americas so do hummingbirds. It survives about -5°C in a sheltered, well-drained spot, especially if mulched, but taking cuttings in late summer is a wise insurance in colder gardens.

Maintenance Calendar

  • Apr Cut the old stems down to new shoots at the base once growth appears, because last year's stems shelter the crown through winter
  • Jun Give a light balanced feed and water in dry spells to keep it flowering
  • Aug Take cuttings of non-flowering shoots as a back-up against a cold winter
  • Nov Leave the stems standing and mulch the crown thickly with dry compost or bark, insulating the roots from frost

Garden Design

Works well in: Cottage, Modern / Contemporary, Wildlife-friendly

Plant in groups near the middle of a sunny border; the dark purple glows next to orange dahlias, lime-green foliage or silver grasses.

Companion planting: Dahlias, Grasses, Cannas, Orange or lime flowers
