Blue Sage – Pollinator Friendly Perennial Choice!
Blue Sage (Salvia superba ‘Merleau Blue’) is a reliable, easy-growing perennial known for its dense spikes of deep violet-blue flowers that appear from late spring through summer. Its compact, upright habit makes it perfect for garden edges, mixed borders, and pollinator-friendly spaces. The aromatic foliage not only adds texture and interest but also discourages deer and rabbits. Blue Sage thrives in full sun and well-drained soil, offering vibrant color even during hot, dry periods. It’s a magnet for bees, butterflies, and hummingbirds, providing consistent nectar when many other plants slow down.
