About Bog sage
Salvia uliginosa, commonly known as Bog Sage, is a vigorous perennial herb prized for its vibrant blue flower spikes that attract pollinators. Its tall, slender stems and light green foliage give it an airy appearance, making it ideal for moist borders, butterfly gardens, or as part of a wildflower meadow.
Native range
South America, especially in Argentina, Uruguay, Paraguay, and southern Brazil.
Care tips
This sage thrives in full sun to partial shade and consistently moist, even occasionally waterlogged, soils, hence its common name. It tolerates a wide range of soil types as long as they retain moisture. A common mistake is planting it in dry soil, which will limit its growth and flowering; ensure ample watering, especially in warm climates.
