Noted for its incredibly dark blue flowers, Corydalis curviflora subsp. rosthornii ‘Blue Heron’ (Fumewort) is a showy, erect perennial forming an attractive mound of lacy, highly divided, blue-green leaves. From late spring to mid-summer, large, very fragrant, sapphire blue flowers are produced atop stunning red stems above the foliage, creating a remarkable contrast. Easy to grow, this Fumewort goes summer dormant in hot areas but can bloom right through to late fall in cool summer areas. Perfect for the shade garden.

  • Grows in clumps, 8-10 in. tall and wide (20-25 cm). Does not self-seed.
  • Best in part shade, in moderately fertile, evenly moist, well-drained soils. Tolerates full shade. Dislikes summer drought.
  • Virtually disease free. Watch for snails and slugs.
  • A great perennial plant for beds and borders, cottage gardens, rock gardens, or woodlands
  • Propagate by division in autumn
