Description
Salvia uliginosa – Bog Sage
Bring a splash of beautiful sky-blue colour to your garden with Salvia uliginosa, commonly known as Bog Sage. This vigorous, flowering perennial produces tall, slender stems covered in delicate blue flowers that add height, movement and a soft, natural feel to garden borders.
A favourite with bees, butterflies and other pollinators, Bog Sage is an excellent choice for wildlife-friendly gardens. Its airy growth habit works beautifully in cottage gardens, mixed perennial borders and naturalistic plantings, where its blue flowers create a lovely contrast against green foliage and other flowering plants.
Unlike many salvias, Bog Sage appreciates consistent moisture and naturally thrives in damp soil. Plant it in full sun to partial shade and provide regular watering, particularly during dry weather. It can spread vigorously through underground runners, making it useful for filling larger spaces but worth monitoring in smaller gardens.
If you love blue flowers and want to encourage more pollinators into your garden, Bog Sage is a wonderful addition.
