Salvia ‘Blue Knight’, commonly known as Meadow Sage, is a fast-growing perennial admired for its upright growth habit and vivid purple-blue flower spikes. Its richly coloured blooms create a striking display in garden beds and are also well suited to cut-flower arrangements.
This hardy salvia performs best in full sun and well-drained soil. It can tolerate occasional hot and dry conditions once established, while cooler temperatures can help maintain strong flowering and vibrant colour. Plant in late spring or early summer for an impressive seasonal display.
With its upright form and vivid flowers, ‘Blue Knight’ is an excellent choice for perennial borders, cottage gardens, pollinator-friendly planting schemes and containers.
