Yarrow ( Achillea millefolium) is a hardy, adaptable herb with a long history of medicinal and practical uses. Whether you're a seasoned gardener or just starting out, propagating yarrow from seed can be a rewarding experience. This guide will walk you through various methods of obtaining yarrow seeds and successfully cultivating this versatile plant.

Harvesting Yarrow Seeds Yourself

The most satisfying way to get yarrow seeds is by harvesting them from your own plants. This guarantees you'll have seeds true to the variety you already grow.

Timing is Key:

Late Summer/Early Autumn: Yarrow flowers produce seeds in late summer and early autumn. Keep an eye on the flower heads; they'll start to turn brown and dry as the seeds mature.
Check for Seed Maturity: The seeds are ready for harvest when the flower heads are completely dry and brittle, and the tiny seeds are easily visible. Gently rub a flower head between your fingers; if the seeds readily detach, they're ready.

Harvesting Techniques:

Cutting the Flower Heads: Cut the entire flower head, including the stem, a few inches below the flower.
Air Drying: Bundle the cut stems together and hang them upside down in a dry, well-ventilated area. A paper bag can protect the seeds from falling out prematurely.
Seed Extraction: Once completely dry (usually a couple of weeks), rub the flower heads vigorously to release the seeds. A screen or fine sieve can help separate the seeds from the chaff.
Seed Storage: Store the collected seeds in a cool, dry, and airtight container. Properly stored yarrow seeds can remain viable for several years.

Purchasing Yarrow Seeds

If harvesting your own seeds isn't feasible, purchasing them is a convenient alternative.

Reliable Sources:

Reputable Seed Companies: Numerous online and brick-and-mortar seed companies offer high-quality yarrow seeds. Research companies with good reviews and a commitment to providing accurate seed descriptions.
Local Nurseries: Check your local nurseries for yarrow seeds or seedlings. They often carry regionally adapted varieties suited to your climate.
Online Marketplaces: While convenient, be cautious when buying seeds from online marketplaces. Verify the seller's reputation and check customer reviews before purchasing.

Choosing the Right Seeds:

Variety Selection: Yarrow comes in numerous varieties, each with varying flower colors, heights, and growth habits. Choose a variety that suits your needs and growing conditions.
Seed Viability: Look for information about seed viability (the percentage of seeds that will germinate). Higher viability rates generally result in better germination success.

Germinating Yarrow Seeds

Successfully germinating yarrow seeds requires some patience and attention to detail.

Sowing Indoors (Recommended):

Starting Time: Start yarrow seeds indoors 6-8 weeks before the last expected frost. This gives the seedlings time to develop before transplanting outdoors.
Seed Starting Mix: Use a well-draining seed starting mix; avoid using garden soil, as it can be too dense for delicate seedlings.
Planting Depth: Sow seeds very shallowly, barely covering them with soil. Yarrow seeds need light to germinate.
Watering: Keep the soil consistently moist, but not waterlogged. Use a spray bottle to gently water the seedlings.
Light: Place the seed trays in a bright, sunny location or under grow lights.

Direct Sowing Outdoors:

Timing: Direct sowing can be done in spring or fall, depending on your climate. Wait until the soil has warmed up in spring, or sow seeds before the first frost in the fall.
Soil Preparation: Prepare the soil by removing weeds and loosening it to improve drainage.
Planting: Scatter the seeds thinly over the prepared soil surface and lightly rake them in.

Troubleshooting

Poor Germination: Poor germination could be due to old seeds, improper planting depth, or inconsistent moisture levels.
Seedling Damping-Off: This fungal disease can affect seedlings, causing them to wilt and die. Ensure good air circulation and avoid overwatering.

Remember, patience is key when growing yarrow from seed. With proper care and attention, you'll soon have a thriving patch of this versatile and beautiful plant. Enjoy the process and the rewards of your homegrown yarrow!
