The Commelina erecta, more affectionately known as the Erect Dayflower or Widow’s Tears, is a charming plant that adds a splash of vibrant blue to any garden.

If you’re looking to expand your blue-hued haven or share this delightful plant with friends, here’s a deep dive into propagating Commelina erecta.

Three Ways to Multiply Your Dayflowers:

Commelina erecta is remarkably versatile when it comes to propagation, offering several methods that even novice gardeners can master:

1. Seed Starting:

  • Timing is Key: Collect seeds from mature flowers in late summer or early fall. You’ll recognize them as small, brown capsules.
  • Sowing the Love: Start seeds indoors 6-8 weeks before the last expected frost. Sow them lightly in a seed-starting mix and keep them consistently moist.
  • Sunlight and Warmth: A warm, sunny windowsill is ideal for germination, which usually takes 2-3 weeks.
  • Transplanting Time: Once the seedlings are sturdy and all danger of frost has passed, transplant them outdoors in a well-drained location.

2. Division:

  • Divide and Conquer (Spring is Best): This method works best in spring when the plant is actively growing. Carefully dig up the entire clump and gently separate it into smaller sections, ensuring each division has roots and shoots.
  • Replanting: Replant the divisions at the same depth they were originally growing and water them well.

3. Cuttings:

  • Snip and Grow: Take stem cuttings about 4-6 inches long from healthy, non-flowering stems in spring or summer.
  • Remove Lower Leaves: Strip off the lower leaves, leaving a few at the top.
  • Rooting Hormone (Optional): While not mandatory, dipping the cut end in rooting hormone can encourage faster root development.
  • Potting Up: Plant the cuttings in a well-draining potting mix and keep the soil consistently moist.
  • Indirect Sunlight is Best: Place the potted cuttings in a location with bright, indirect sunlight.
  • Patience is a Virtue: Roots usually develop in a few weeks. Once you see new growth, you can transplant your rooted cuttings outdoors.

Tips for Success:

  • Well-Drained Soil is a Must: Commelina erecta thrives in loose, well-drained soil. Amend your garden bed with compost if drainage is an issue.
  • Sun or Shade, It Adapts: While it prefers partial shade, Commelina erecta can tolerate full sun in cooler climates.
  • Water Wisely: Keep the soil moist but be careful not to overwater, which can lead to root rot.
  • Deadheading Encourages More Blooms: Pinching off spent flowers can prolong the blooming period and prevent unwanted self-seeding.

Propagating Commelina erecta is a rewarding experience, allowing you to expand your garden with minimal effort. With its stunning blue blooms and adaptable nature, this easy-to-grow plant is a wonderful addition to any garden setting. So, go ahead and spread the blue love!
