Blue Spike Salvia

Blue Spike Sage or Bog Sage (Salvia uliginosa) is becoming a very popular species, enjoyed for its long blooming display of sky-blue flowers, large bushy habit, and exceptionally resilient garden performance. A big growing sage that spreads by underground rhizomes, it grows in both wet and dry soil conditions. Blue Spike Sage grows in most any soil type and tolerates both sun and partial shade. Native to southern Brazil, Argentina, and Uruguay, it won the Royal Horticultural Society’s Award of Garden Merit for its outstanding performance in England and Europe.
