Salvia Indigo Spires (Sage)
Prized by gardeners, Salvia ‘Indigo Spires’ is a vigorous shrubby perennial with masses of long, twisted spikes of indigo blue flowers held in dusky purple calyces. Blooming continuously from early summer to frost, the waving flowering stems, up to 15 in. (37 cm), are held well above the foliage of dark green, ovate leaves. Well-branched and very free-flowering
Prized by gardeners, Salvia 'Indigo Spires' is a vigorous shrubby perennial with masses of long, twisted spikes of indigo blue flowers held in dusky purple calyces. Blooming continuously from early summer to frost, the waving flowering stems, up to 15 in. (37 cm), are held well above the foliage of dark green, ovate leaves. Well-branched and very free-flowering, this terrific sage is perfect for beds and borders where it adds a long season of color. Almost iridescent in the fall, the flowers dry well and hold their color in flower arrangements.
- Grows up to 3-4 ft. tall (90-120 cm) and 2-3 ft. wide (60-90 cm).
- Thrives in full sun or light shade, in moist, well-drained soils. Water and fertilize regularly to keep it flowering. Provide winter protection in zone 7.
- Great choice for cut flowers borders, edging, mass planting.
- Attracts butterflies and hummingbirds but is ignored by hungry deer.
- Pinch stem tips early in the growing season and deadhead the faded flower spikes to promote more blooms.
