How to Grow Allium Campanulatum from Seeds:

  • Cold stratification is recommended for improved germination. Store seeds in a moist paper towel inside a plastic bag and refrigerate for 4 to 6 weeks
• Sowing Method:
  • Sow seeds ¼ to ½ inch deep in a well-drained seed-starting mix or directly outdoors in a prepared garden bed
  • Keep the soil consistently moist, but ensure it’s not waterlogged
  • Germination time: Typically takes 3 to 4 weeks at 65 to 70°F (18 to 21°C)
• Spacing:
  • Space plants 8 to 12 inches apart to allow for proper growth and air circulation

Transplanting and Care:

• Once seedlings have developed two sets of true leaves, transplant them to their final garden location
• Allium campanulatum thrives in full sun but can tolerate partial shade, making it perfect for meadow-style gardens and border plantings

Care and Maintenance Tips:

• Watering: Water moderately during the growing season, but reduce watering once the plant is established and the foliage begins to die back
• Fertilization: Apply a low-nitrogen fertilizer in early spring to encourage strong growth and flowering
• Pruning: Deadhead spent flowers to encourage re-blooming and maintain a tidy appearance
• Winter Care: Apply mulch around the base in colder climates for winter protection

Perfect Companion Plants:
