🌿 Tasty Tuesday Herb Spotlight: Comfrey

Common name: Comfrey 
Botanical name: Symphytum officinale 
Family: Boraginaceae

A powerhouse in the garden, comfrey is best known not for the kitchen—but for its incredible value as a soil builder, compost booster, and traditional herbal plant. With its broad leaves and clusters of bell-shaped flowers, comfrey is both functional and beautiful, earning its place in permaculture gardens and herbal landscapes alike.

🌱 Why Grow Comfrey?

1. Garden Super Plant 
Comfrey’s deep roots pull nutrients like potassium, calcium, and phosphorus up from the soil, making it an excellent natural fertilizer.

2. Compost Booster 
Its leaves break down quickly and add rich nutrients to compost piles or can be used as a mulch.

3. Pollinator Friendly 
Bees love comfrey’s nectar-rich flowers, making it a great addition to support beneficial insects.

4. Traditional Herbal Use 
Historically used in salves and poultices for skin and external applications.
