Hedgerow Plants and Browse – Knowing your options

Written by Briony Witherow MSc RNutr. FHEA
Hedgerow plants and browse can be a great way to add variety to your horse’s diet, encourage natural foraging behaviour, and provide additional nutrients. However, correct identification is essential — some plants are safe, while others can be highly toxic.
Hedgerow Options
The following can be fed in moderation. Lower sugar options are shown in bold for those on a low-sugar ration:
- Alder
- Birch
- Blackberry leaves/bramble (supervision advised)
- Blackthorn
- Bog rush/marsh foxtail/common reed
- Comfrey
- Cow parsley (matt leaves; celery-like grooves on stem — see misidentification notes below)
- Dandelions
- Dogrose
- Dogwood
- Gorse
- Hawthorn (supervision advised)
- Hazel
- Poplar
- Quickthorn
- Raspberry leaves
- Sticky weed (cleavers)
- Sweet briar rose or rosa rugosa
- Thistles
- Willow (limited quantities)
- Wilted nettles
Misidentification Risks
Some safe species have dangerous lookalikes. The most common mistakes include:
· Cow Parsley vs Hemlock – Both are white-flowering umbellifers with similar leaves, but Hemlock has shiny leaves, red/purple blotches on the stem, and no celery-like grooves. Hemlock is poisonous and must be avoided.
· Cow Parsley vs Common Hogweed – Common Hogweed has a wider leaf than Cow Parsley. Giant Hogweed, a much larger relative, has purple-spotted stems and toxic sap that can burn skin.
· Hawthorn and Blackthorn – While both are generally safe browse, their thorns can cause injury; offer only under supervision.
Feeding and Enrichment Ideas
· Make a hedgerow haynet – fill a haynet with a mix of safe browse and hang in the stable or field shelter to mimic natural browsing behaviour.
· Add browse to your paddock or field – secure small bundles of safe cut branches at a safe height, encouraging exploration and interaction.
Safety Tips
· Introduce any new browse gradually, in small quantities.
· Only feed plants you are confident in identifying.
· Source from areas free of pesticides, herbicides, and heavy traffic.
· Supervise where thorny plants are offered.
· If in doubt — leave it out.
Take-Home
Hedgerow plants can be a valuable addition for enrichment, especially for horses stabled for long periods of time. Correct identification is the key to reaping the benefits safely. For low-sugar diets, focus on the bold options above, and consider creative ways to offer browse to keep horses engaged and foraging naturally.
