Taming the Green Albatross: Propagating Pentaglottis Sempervirens

Pentaglottis sempervirens, also known as the Green Albatross or Evergreen Bugloss, is a captivating plant with its vibrant blue flowers and lush foliage. While its beauty is undeniable, gardeners often approach its propagation with a mix of excitement and trepidation. But fear not! This guide will demystify the process and empower you to cultivate more of this striking plant.

Understanding Pentaglottis Sempervirens

Before we delve into propagation techniques, it’s crucial to understand the plant’s growth habits. This perennial boasts an impressive ability to self-seed, sometimes a bit too enthusiastically, hence the “Albatross” moniker. This characteristic makes it essential to choose your propagation method carefully.

Method 1: Division – The Tried and True

For a controlled approach, division reigns supreme. This method involves separating established clumps to create new plants.

When to Divide: Early spring or fall is ideal, avoiding the peak heat of summer.

Steps:

  1. Dig Deep: Carefully lift the entire clump from the ground, ensuring you get as much of the root system as possible.
  2. Divide and Conquer: Use a sharp spade or garden knife to slice through the roots, creating smaller sections with healthy foliage and roots.
  3. Replant: Choose a well-drained location with partial shade and plant the divided sections at the same depth they were originally growing. Water thoroughly.

Method 2: Root Cuttings – A Rewarding Challenge

If you’re feeling adventurous, try your hand at root cuttings. This method takes advantage of the plant’s ability to regenerate from root segments.

When to Take Cuttings: Late fall or early winter is the optimal time when the plant is dormant.

Steps:

  1. Unearth Potential: Carefully expose a portion of the plant’s roots.
  2. Cut Strategically: Choose healthy roots that are pencil-thick and cut them into 2-3 inch segments.
  3. Prepare the Planting Medium: Fill a tray or pot with a well-draining seed-starting mix.
  4. Plant Horizontally: Lay the root cuttings horizontally on the surface of the mix and cover them lightly with soil.
  5. Patience is Key: Keep the mix consistently moist and place the tray in a cool, shaded location. New shoots should emerge in a few weeks.

Managing Self-Sown Seedlings

Pentaglottis sempervirens is a prolific self-seeder. While this can be beneficial, it can also lead to overcrowding.

Thinning the Herd: Don’t hesitate to remove unwanted seedlings. You can easily pull them up or transplant them to other areas of your garden.

Conclusion

Propagating Pentaglottis sempervirens doesn’t have to be an intimidating endeavor. Whether you choose the time-tested method of division or embark on the journey of root cuttings, understanding the plant’s growth habit is key to success. With a bit of patience and the right techniques, you’ll be enjoying vibrant blue blooms and lush foliage for years to come.
