Planting & seasonal timing
Northern Hemisphere planting months: not yet verified in our database.
Northern Hemisphere pruning months: November, December.
For the Southern Hemisphere, these seasonal windows shift approximately six months. Check your local frost forecast, soil temperature, and species requirements; calendar months are not a guarantee of planting safety.
Needs full shade to maintain best blue color - sun burns off the waxy coating. Thick leaves provide excellent slug resistance. Keep well-watered in summer heat.
Pruning
Cut back dead foliage after frost. Remove flower stalks after blooming.
Fertilizer
Balanced slow-release
Early spring
Mulch
2-3 inches of organic mulch.
