About this guild
Calendula, comfrey, echinacea, lemon balm, and nettle support both apothecary use and garden ecology — comfrey as potassium mulch, calendula for beneficial insects, echinacea for late pollinator food.

Planting tips
- Contain mint, lemon balm, and nettle — root barriers or pots.
- Comfrey: chop-and-drop only; do not eat unless you know safe cultivars.
- Plant calendula on bed edges for easy deadheading and self-seeding.
