How to Propagate Stipa borysthenica

Taming the Wild Feathers: A Guide to Propagating Stipa borysthenica

Stipa borysthenica, also known as the Ukrainian feather grass, is a stunning ornamental grass known for its delicate, feathery plumes that dance gracefully in the wind. It adds a touch of airy elegance and movement to any garden, creating a captivating display. While readily available in nurseries, propagating your own Stipa borysthenica can be a rewarding experience. Let’s explore the two main methods – division and seed propagation.

Division: The Simplest Approach

Dividing established clumps is the easiest and most common way to propagate Stipa borysthenica. This method ensures that the new plants will exhibit the same desirable characteristics as the parent plant.

When to divide: Spring is the ideal time for division when the plant is actively growing.

Here’s how:

  1. Prepare the ground: Choose a sunny location with well-drained soil. Amend the soil with compost or other organic matter to enhance drainage and fertility.
  2. Lift the clump: Using a sharp spade or garden fork, carefully lift the entire clump of Stipa borysthenica from the ground.
  3. Divide the clump: Gently tease apart the clump into smaller sections, ensuring each section has a good amount of roots attached.
  4. Replant the divisions: Plant the divisions at the same depth they were originally growing. Space them about 2 to 3 feet apart to allow for adequate airflow and future growth.
  5. Water thoroughly: Water deeply after planting to settle the roots and eliminate any air pockets.

Seed Propagation: A Test of Patience

While slightly more challenging than division, propagating Stipa borysthenica from seed allows you to grow a larger number of plants and witness their life cycle from the very beginning.

When to Sow: Seeds can be sown directly outdoors in fall or started indoors in late winter.

Here’s how:

  1. Seed Collection: Collect ripe seeds from existing plants in late summer or early fall. Look for seed heads that have turned a light brown color.
  2. Direct Sowing (Fall): Sow seeds directly into prepared garden beds in the fall. Scatter them evenly over the surface and lightly rake them in.
  3. Indoor Sowing (Late Winter): Sow seeds indoors 6-8 weeks before the last expected frost. Use seed trays filled with a well-draining seed starting mix. Sprinkle a thin layer of vermiculite over the sown seeds to retain moisture.
  4. Transplant Seedlings: Once the seedlings have developed a strong root system and the danger of frost has passed, transplant them into individual pots or directly into the garden.

Important Tips:

  • Patience is Key: Both division and seed propagation require patience. It may take a year or two for the new plants to establish themselves and reach their full size and flowering potential.
  • Provide Adequate Sunlight: Stipa borysthenica thrives in full sun. Ensure the plants receive at least 6 hours of direct sunlight per day.
  • Water Deeply but Infrequently: Once established, Stipa borysthenica is relatively drought-tolerant. Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
  • Divide Regularly: Dividing your Stipa borysthenica every few years will help maintain its vigor and prevent the center of the clump from dying out.

Propagating Stipa borysthenica, whether through division or seed, is a rewarding endeavor. With a little care and patience, you can enjoy the beauty and elegance of these feathery plumes for years to come.
