Salvia 'Blue Queen', commonly known as Blue Queen Meadow Sage, is a compact, deciduous perennial valued for its vibrant blue-violet flower spikes. It typically grows to a height of 40–60 cm with a spread of about 30–45 cm, forming a dense, clump-forming habit. The plant features aromatic, lance-shaped green leaves and produces tall, upright spikes of deep blue flowers from late spring to early autumn, attracting bees, butterflies, and other pollinators. It is commonly used in borders, cottage gardens, and pollinator-friendly plantings due to its extended blooming period, drought tolerance, and low-maintenance requirements.
