Golden Glory Multiplied: Propagating Showy Goldenrod (Solidago latissimifolia)
Showy Goldenrod, also known as Solidago latissimifolia, is a North American native plant that lights up autumn gardens with its vibrant yellow plumes. Unlike its weedy cousin, Canada Goldenrod, Showy Goldenrod stays well-behaved in the garden setting and offers a burst of late-season color that attracts pollinators. If you’re looking to expand your goldenrod display or share its beauty with friends, propagation is surprisingly simple. Let’s explore the best ways to multiply your Showy Goldenrod.
Division: The Go-To Method
The easiest and most effective propagation technique for Showy Goldenrod is division. This method takes advantage of the plant’s natural growth habit of forming clumps from its rhizomatous root system.
- When to Divide: Early spring, just as new growth emerges, is the ideal time. However, you can successfully divide in the fall as well.
- Tools You’ll Need: A sharp spade or garden fork, gardening gloves, and a bucket or tarp to hold the divisions.
- Process:
- Water the plant thoroughly the day before dividing to reduce stress.
- Carefully dig around the clump, ensuring you’re a few inches away from the outer stems to avoid damaging the roots.
- Lift the entire clump out of the ground, gently shaking off excess soil.
- Using your hands or the spade, carefully separate the clump into smaller sections, each containing healthy roots and shoots.
- Replant the divisions immediately at the same depth they were growing before, spacing them 1 to 2 feet apart.
- Water thoroughly and mulch around the base to retain moisture.
Taking Cuttings: For The More Adventurous Gardener
While not as common as division, Showy Goldenrod can be propagated through stem cuttings. This method requires a bit more patience but can be rewarding.
- When to Take Cuttings: Late spring or early summer is the optimal time for successful rooting.
- What You’ll Need: Clean, sharp pruning shears, a rooting hormone (optional but recommended), a soilless seed-starting mix, and small pots or trays.
- Process:
- Choose healthy, non-flowering stems around 4-6 inches long.
- Make a clean cut just below a leaf node using your sharp shears.
- Remove the lower leaves, leaving 2-3 pairs at the top.
- Dip the cut end in rooting hormone (optional), and then gently insert the cutting into the moistened seed-starting mix.
- Cover the pots with a plastic bag or humidity dome to maintain moisture and warmth.
- Place the cuttings in a bright location but out of direct sunlight.
- Keep the soil consistently moist.
- After 4-6 weeks, check for root development by gently tugging on the cuttings. If they resist, roots are forming!
- Once rooted, transplant into larger pots or directly into the garden.
Enjoying the Golden Rewards
With either division or stem cuttings, propagating your Showy Goldenrod allows you to increase your plant collection and share this delightful native plant with others. By following these steps, you’ll soon have multiple golden plumes gracing your garden and attracting pollinators with their late-season beauty.
