Growing Guide · Wild Healer's Trio
Picture it: comfrey's nodding bells buzzing with bumblebees, flat white plates of yarrow in the long grass, and a plantain leaf always within reach when someone gets stung.
The Wild Healer's Trio brings together three of the oldest healing plants of British hedgerows and waysides: comfrey, yarrow and plantain. Tough, generous and full of history, here's how to grow them.

The Wild Healer's Trio is three hardy, wildlife-friendly herb plants: comfrey, yarrow and plantain, traditional wayside healers of the British countryside. Plant them in spring or autumn in sun or part shade. Comfrey grows large (around 1m tall and wide) with deep roots, so give it a permanent spot or a big container; yarrow spreads gently and loves dry sun; plantain stays low. All three are tough perennials that return every year.
Why grow a wild healer's garden?
These are the plants people reached for when they were miles from a doctor: the leaf for a sting, the poultice for a bruise. They're tough, easy and brilliant for wildlife, and they bring a wilder, meadow feel to a corner of the garden.
- Almost impossible to fail with. All three are robust natives or naturalised wayside plants that thrive with little help.
- A garden that feeds itself. Comfrey leaves make one of the best free plant feeds and compost activators there is.
- Wildlife magnet. Bumblebees adore comfrey, and yarrow's flat flowers feed hoverflies and butterflies.
- Living history. Every plant here has centuries of folklore and traditional use.

What to expect: heights and habits
These are vigorous, easy plants. The main thing to plan for is comfrey's size.
| Herb | Height | First year | Watch out for |
|---|---|---|---|
| Comfrey | Up to 1m, and 1m wide | Settles in, then grows fast | Deep roots; any piece of root left in the ground regrows |
| Yarrow | 30–60cm | Quick; flowers the first summer | Spreads by creeping roots into a patch |
| Plantain | 10–30cm | Quick; a low leafy rosette | Seeds itself if the flower spikes are left |
Choose comfrey's spot for keeps. Comfrey grows into a big clump about a metre tall and wide, with deep roots that are almost impossible to dig out: any piece of root left behind grows a new plant. Plant it where it can stay for good, such as a back corner or near the compost heap, or grow it in a large container (45cm+) to keep it contained.
Cut comfrey three or four times a summer. It bounces straight back, and every cutting gives you leaves for plant feed and compost.
Yarrow and plantain spread gently. Pull up stray yarrow runners in spring, and snip plantain's flower spikes before they seed.
Where to plant your collection
These plants like it informal. They suit a sunny meadow edge, a wildlife corner or the end of the vegetable plot.
Back · largest
Front · sunny and dry
Growing in pots? Yarrow and plantain are both happy in 25–30cm pots. Comfrey needs a large, deep container (45cm+), which is also the easiest way to stop it spreading. A container also keeps comfrey handy for cutting by the potting bench.
The folklore behind your herbs
These are some of the oldest healing plants in Britain, and their stories show it.
🌿 Comfrey, knitbone
Its old names, "knitbone" and "boneset", and its Latin name Symphytum, from the Greek for "to grow together", come from centuries of use on bruises and sprains. Medieval monks grew it in their infirmary gardens.
⚔️ Yarrow, Achilles' herb
Its Latin name, Achillea, comes from the legend that Achilles used it on his soldiers' wounds at Troy. Yarrow stalks were used to cast the ancient Chinese I Ching, and it was tucked into wedding bouquets for seven years of love.
👣 Plantain, the waybread
One of the nine sacred herbs of the Anglo-Saxon Nine Herbs Charm, where it was called "waybread". It followed European settlers so faithfully that Native Americans called it "white man's footprint".
An afternoon in your wild herb garden
It's a hot afternoon in late June. You're weeding the vegetable bed when something stings your wrist.
You don't go inside. You reach for a plantain leaf, crush it between your fingers and press it on, the way country children have done for hundreds of years.
Beside you, the comfrey is humming with bumblebees, its bells nodding under their weight. You cut an armful of its leaves for the water butt, and in a few weeks they'll be a rich, free feed for your tomatoes.
Further along, the yarrow is in full flower, flat white plates covered in hoverflies. That's what this corner is for: a little wildness, a lot of life, and plants that look after you and the rest of the garden.
What can you use your wild healers for?
These plants have long histories of traditional use, mostly on the skin.
🌿 Comfrey
The leaves and root are traditionally used in poultices, ointments and balms for bruises, sprains and aching joints, applied to unbroken skin. In the garden, the leaves make a rich liquid plant feed and a brilliant compost activator.
⚔️ Yarrow
Traditionally used for cuts and grazes, and as a hot tea to help with fevers and colds. The flowers dry beautifully for posies and wreaths.
👣 Plantain
The leaves are traditionally used for stings, bites, splinters and scrapes, crushed and laid straight on the skin. They're also used in soothing salves.
Make comfrey plant feed: stuff a bucket with chopped comfrey leaves, weigh them down, top up with water and cover. After four to six weeks, dilute the dark liquid about one part to ten with water and use it on tomatoes, beans and pots. It smells, but your plants will love it.

Using your herbs safely: comfrey is for external use only. Don't eat or drink it, and don't use it on broken skin or for long periods. Yarrow is not suitable during pregnancy and can cause reactions in people allergic to daisy-family plants.
Always speak to a qualified herbalist or healthcare professional before using herbs for health, especially if you're pregnant, breastfeeding or taking medication.
