Buying & Getting Asparagus Seeds

Asparagus is a long-term crop, and starting with the right seed makes all the difference. Many gardeners wonder whether to collect seed from their own plants or to buy fresh seed each year. Let’s break down both options.

How to Get Seeds from Asparagus

• Asparagus plants produce fern-like growth after the spears are harvested. In late summer, female plants form clusters of small red berries.
• Each berry contains several black seeds, which can be collected once the berries ripen and turn bright red.
• To save asparagus seeds:
  1. Pick ripe red berries.
  2. Split them open and wash the seeds free of pulp.
  3. Dry thoroughly on paper towels.
  4. Store in a cool, dry, airtight container.

This process is simple, but remember that not all saved seed will germinate as reliably as commercial seed.

How Do You Get Asparagus Seeds from the Plant?

• Only female asparagus plants produce berries, so you’ll need both male and female plants in your patch to set seed.
• Once the berries ripen, seeds can be collected as above.
• However, seed-grown plants from your own asparagus bed may not always come true to type, meaning they can vary in thickness, vigour, and yield.

Where to Get Asparagus Seeds

For most growers, it’s best to buy fresh seed each season from a reliable supplier. This ensures:

• High germination rates – fresher, properly stored seed sprouts more quickly.
• True-to-type plants – guaranteed variety, so you know the size and quality of spears you’ll get.
• Disease-free stock – commercial seed is cleaned and inspected, reducing the risk of introducing problems into your garden.

Where Can I Buy Asparagus Seeds?

In the UK, asparagus seeds can be purchased from reputable online seed companies, garden centres, and specialist vegetable seed suppliers. For consistent results and strong varieties, always choose a trusted brand.

Should You Save or Buy?

• Save your own seed if you already have a healthy asparagus bed and don’t mind some variation in future plants.
• Buy fresh seed if you want predictable results, strong plants, and a guaranteed variety.

Most gardeners choose to buy seed, at least for starting a new bed, as it saves time and avoids disappointment.
