True Comfrey (Symphytum officinale) – 20 Seeds

Grow true comfrey, Symphytum officinale, from a packet of approximately 20 seeds supplied by Seed Therapy. This is seed for planting, not a live plant, root cutting, dried herb or finished skin-care product.

Comfrey is a leafy perennial with bell-shaped flowers visited by bees. Gardeners also use its cut foliage as compost material. Choose a planting location carefully: established comfrey can spread and may be difficult to remove completely.

True Comfrey Seed and Growing Details

The following specifications are the supplier’s published guidance. Growing results depend on climate, seed condition, preparation and care.

How to Start True Comfrey Seeds

Seed Therapy recommends outdoor fall sowing for a natural cold period. For spring planting, it recommends 30 days of cold, moist stratification in the refrigerator before sowing. Plant the seeds ¼ inch deep.

Cold stratification is a preparation step, not a promise that seedlings will appear within 30 days. Follow the current packet instructions and avoid allowing the growing medium to dry out or become waterlogged.

Review the supplier’s current true comfrey growing instructions before planting.

Choose a Long-Term Planting Location

True comfrey is not a temporary annual planting. North Carolina Extension notes that it spreads readily and can regrow from root pieces left behind during removal. Avoid placing it where you expect to dig, divide or redesign the bed frequently.

Before planting, check regional suitability and decide how you will manage unwanted growth. This species originates outside North America; an American-grown seed claim does not mean that the plant is native to the United States.

Read the North Carolina Extension true comfrey plant profile for growing conditions, spreading behavior and toxicity information.

True Comfrey vs. Bocking 14

This packet is identified as Symphytum officinale. It is not Bocking 14, the sterile Russian comfrey hybrid Symphytum × uplandicum ‘Bocking 14’.

The Royal Horticultural Society identifies Bocking 14 as sterile and recommends propagation by division or root cuttings. Do not purchase this seed packet expecting that cultivar’s non-seeding behavior.

Compare the RHS Bocking 14 cultivar description when deciding which type of comfrey fits your garden.

Garden Uses and Safety

Comfrey foliage can be incorporated into garden compost. Its flowers also provide a reason to include it in a carefully managed ornamental planting. These gardening uses do not establish that the plant is suitable for eating or home medical treatment.

For information about the plant’s toxic compounds, see the USDA Agricultural Research Service’s comfrey toxicity research summary.

American-Grown Seed

Seed Therapy identifies this product’s seed origin as American grown. That statement concerns where the seed was grown, not the native range of the species or the origin of every packaging component.
