How to Propagate Symphyotrichum drummondii

From One to Many: The Simple Joy of Propagating Symphyotrichum Drummondii

Symphyotrichum drummondii, commonly known as Drummond’s aster, is a beautiful wildflower that bursts into vibrant blooms in late summer and early fall. It’s known for its striking blue to purple daisy-like flowers, adding a splash of color to gardens and attracting pollinators galore. But did you know you can easily multiply your own Drummond’s aster?

Propagation, the process of creating new plants from existing ones, is a rewarding activity that offers a fantastic way to increase your garden’s diversity and share the beauty of these wildflowers with others. Best of all? Propagating Drummond’s aster is surprisingly simple and offers several methods to choose from.

1. The Magic of Seeds:

Drummond’s aster readily produces seeds, offering a straightforward way to create new plants. Here’s how:

  • Harvesting Seeds: Once the flower heads have faded, the seeds will mature within the dried flower stalks. Collect the seeds by gently rubbing the seed head into a paper bag or container.
  • Sowing Seeds: Directly sow the seeds in the garden in the spring after the last frost. You can also start seeds indoors a few weeks before the last frost date for an earlier blooming season.
  • Thinning Out: When seedlings emerge and reach a few inches tall, thin them out, leaving the strongest plants spaced a few inches apart.

2. The Art of Division:

For more immediate gratification, try dividing established plants. This method is best done in the spring or fall and can be done in a few easy steps:

  • Dig the Plant: Carefully dig up the plant, trying to preserve as much of the root system as possible.
  • Divide the Roots: Separate the plant into several smaller divisions, each with healthy roots and foliage.
  • Replant and Water: Replant the divisions in a new location ensuring the root ball is just below the soil level. Water them thoroughly.

3. The Power of Cuttings:

While less common, propagating Drummond’s aster using cuttings can be successful if you have access to a well-established plant. This method involves taking stem cuttings during the spring or summer months:

  • Take the Cutting: Cut a 4-6 inch piece of stem just below a leaf node. Remove the bottom leaves, leaving just a couple of leaves at the top.
  • Prepare the Cutting: Dip the cut end of the stem in rooting hormone to encourage root development.
  • Plant the Cutting: Place the cutting into a well-draining potting mix and water it thoroughly.
  • Provide Humidity: Keep the cutting environment humid, ideally with a humidity dome.

From Seeds to Sharing:

No matter the method you choose, be sure to provide appropriate care to your newly propagated plants, including sunlight, water, and well-draining soil. With a little attention and care, you’ll soon be enjoying the stunning spectacle of Drummond’s aster blooming in your garden.

Beyond your own garden, share your extra plants with friends and neighbors. This beautiful wildflower is sure to find a loving home, spreading joy and pollinators wherever it goes. And as you watch new life bloom from just a handful of seeds or a division of foliage, you’ll experience the rewarding satisfaction of bringing nature to your home. The world of propagation is waiting, why not give it a try?
