Salvia guaranitica 'Black & Blue'

Salvia guaranitica 'Black & Blue' | This is a stunning Salvia which can reach heights of 2.5m so a real impact plant great for back of sunny borders. From late summer to mid-autumn, 30cm long upright spikes carry sumptuously coloured purple-blue flowers, which are held at their bases by near-black calyces - hence the name 'Black and Blue'. Good for bees and butterflies.
