Comfrey Seeds

Symphytum officinale, or Common Comfrey, is a robust Hardy Herbaceous Perennial (H7). Unlike the sterile 'Bocking 14' clone, this native species will set seed and naturalise. It is an essential component of permaculture "guilds," valued for its ability to cycle nutrients and improve soil structure in orchards and wilder garden areas.

The "Knitbone" Legacy: Historically known as "Knitbone" or "Boneset," Comfrey has been used for centuries in traditional folk medicine as a topical salve. In the modern garden, however, its primary value lies in its exceptional NPK ratio (approx. 1.8-0.5-5.3), making its foliage a premium source of organic potassium.

Bumblebee Biology: Comfrey flowers are specifically structured for long-tongued bumblebees. The nectar re-fills remarkably quickly—sometimes in under an hour—meaning a single plant can provide a nearly continuous food source for a colony throughout the late spring and summer months.

Comfrey is virtually indestructible once established, though starting from seed requires a patient approach.

How to Sow:
Sow indoors in Spring or Autumn. The seeds possess a tough outer coating; we recommend soaking them in warm water for 12 hours prior to sowing to improve germination rates. Surface sow into moist compost and cover lightly. Maintain a temperature of 15-18°C. Germination can be irregular, typically taking between 2-5 weeks.

Where to Plant:
Comfrey is remarkably versatile, thriving in both full sun and deep shade. It is particularly well-suited to heavy, damp clay soils where other plants might struggle. Once established, its taproot can reach depths of over 2 metres, making it exceptionally drought-tolerant.

The "Chop and Drop" Method:
For maximum garden benefit, use the "Chop and Drop" technique. Cut the foliage down to ground level 3-4 times per year. The leaves can be used immediately as a nutrient-rich mulch around hungry plants like tomatoes and fruit trees, or steeped in water for 3 weeks to create a high-potash liquid organic feed.

Comfrey is the unsung hero of the organic garden. Use it to feed and support these available partners from our range:

• 🍎 Fruit Tree Guilds: The Living Mulch. Plant Comfrey in a ring around the base of your fruit trees. Its leaves act as a natural potassium pump, while its large foliage suppresses competing grass and weeds. This is a classic permaculture technique for building long-term orchard health.
• 💙 Borage: The Pollinator Powerhouse. Comfrey and Borage are botanical cousins. Planting them together creates a relentless nectar station that supports bees and butterflies from late spring until the first autumn frosts, whilst both provide excellent material for compost activation.

Sow in spring or autumn for a permanent, indestructible source of organic fertilizer and high-nectar flowers.
