Foraged Halloween displays: which berries, branches and gourds to keep out of reach

A foraged Halloween display looks wonderful. A sprig of something dark, a few bright berries from the hedge, a bowl of gourds and a jug of Chinese lanterns. It also brings plants that normally live up a tree or across a field down to the coffee table, where toddlers and dogs can reach them.

Most of it is low risk. Ireland's National Poisons Information Centre notes that toxic plants can cause substantial symptoms, but these "are not seen in most cases of accidental ingestion." But one or two common choices are genuinely dangerous, so it's worth knowing which.

01At a glance

Leave out entirely: yew, lords-and-ladies and any nightshade berries. Yew foliage and seeds are seriously poisonous, and the berries of lords-and-ladies and woody nightshade can cause serious illness.
Keep well out of reach: spindle and Chinese lantern berries.
Mild, but still not food: ivy and holly berries.
Not poisonous plants, but still trouble: ornamental gourds eaten by mistake, mouldy pumpkins, corn cobs and candles.
If eaten: for pets, ring your vet or the Animal PoisonLine on 01202 509000. It is a paid 24-hour service (£35–£45 a call). If you think a child may have swallowed something harmful, call 999 or go to A&E. Call NHS 111 if you're not sure.

02Ranked by real risk

Yew. The one to leave out. The RHS lists Taxus as toxic if eaten. The Woodland Trust says the red flesh around the seed isn't toxic, but the seed inside is poisonous to people, and so are the bark and leaves. It adds that just a few leaves can make a small child severely ill. The ASPCA lists yew as toxic to dogs, cats and horses, with sudden death from heart failure among the signs. Our yew profile rates it lethal. Dark yew sprigs look perfect in a spooky arrangement. Use something else.
*Lords-and-ladies (Arum maculatum). The spikes of glossy orange-red berries on woodland edges. The Woodland Trust calls the berries "particularly poisonous", with eating them causing throat swelling, breathing difficulty and stomach irritation. The acrid taste usually stops anyone eating much. The ASPCA lists it as toxic to dogs, cats and horses, with intense mouth burning and drooling. Don't confuse it with our arum lily, which is the garden calla, Zantedeschia*.
*Woody nightshade, or bittersweet (Solanum dulcamara). Trails of shiny red berries through autumn hedges. The Wildlife Trusts say it is less toxic than many nightshades, but its berries "are still poisonous" and "can cause serious illness." It is not deadly nightshade (Atropa*), whose black berries the Woodland Trust warns can be fatal in small numbers. Neither belongs in a display.
Spindle. Those pink fruits splitting to show orange seeds. The Woodland Trust says the leaves and fruit are toxic to humans, with a laxative effect. The RHS calls Euonymus "somewhat poisonous". Our spindle profile flags the berries as the main temptation for pets and children.
*Chinese lanterns (Physalis alkekengi).* The RHS lists them as harmful if eaten, except the ripe fruit. The veterinary toxicology guide on IVIS says the leaves and unripe fruit carry solanine-type alkaloids, though poisoning is rarely reported. The papery lanterns are fine to look at. Don't let anyone pick out the berry and eat it.
Ivy berries. The Woodland Trust calls ivy mildly poisonous if eaten. For pets, the ASPCA notes the foliage is more toxic than the berries, and lists vomiting, drooling and diarrhoea. Our ivy profile says the sap irritates skin, so wear gloves cutting it.
Holly. The ASPCA rates holly leaves and berries as low toxicity for cats, dogs and horses, causing vomiting and diarrhoea. See our holly profile.
Conkers and acorns. A bowl of them is an autumn classic. For dogs they are a real risk, and our autumn danger calendar covers why. Keep the bowl high.

03Not poisonous plants, but still trouble

Ornamental gourds. Bought to look at, not to eat. Switzerland's poisons centre, Tox Info Suisse, says ornamental squashes contain bitter, toxic cucurbitacins and are only intended for decoration. Symptoms are nausea, vomiting and diarrhoea. US Poison Control adds that cooking does not destroy the toxin. The real risk is someone cooking the display afterwards. Its advice for any squash: "If it is bitter, spit it out and throw it away."
Pumpkins going mouldy. A carved pumpkin left on the step for a week becomes mouldy food. The ASPCA warns that fungal toxins on old food can cause vomiting, tremors and seizures in dogs, with a fast onset. Get rid of it before it goes soft; after the carving covers how. Our pumpkin profile has more on the plant itself.
Dried corn cobs. The PDSA has treated dogs that needed surgery after swallowing corn on the cob, which can cause a "life-threatening blockage". Our sweetcorn profile says the same of spent cobs. Decorative dried cobs are no different.
Candles. The ASPCA warns that pets can knock over a lit pumpkin and start a fire, and that kittens can be singed. A battery tea-light does the same job.

04Rules for a home-made display

Know what you've picked. If you can't name it, don't bring it in. The RHS rule is simple: "If it is not a food plant, do not eat it."
Display at adult height. Mantelpiece, not coffee table. Bowls of berries and conkers go where paws and small hands can't reach.
Sweep up drops daily. Berries fall as they dry.
Wear gloves, wash hands. The RHS advises gloves and covered skin when handling plants. Ivy sap irritates skin.
Tell the children. The National Poisons Information Centre says teach children not to put any part of a plant in their mouths. Supervision is the real safeguard.
Bin it, don't cook it. Display gourds go in the compost, not the soup.

The lower-risk choices are the obvious ones: edible pumpkins and squash, seed heads and branches you have identified, and dried flowers you grew yourself.

05If something gets eaten

Pets. Take the plant away and don't try to make your pet sick. Ring your vet or the Animal PoisonLine, run by the Veterinary Poisons Information Service, on 01202 509000. It is a paid 24-hour service (£35–£45 a call).
People. If you think a child may have swallowed something harmful, call 999 or go to A&E. Call NHS 111 if you're not sure. Don't try to make them sick, and take a sample of the plant with you.

Save your money

Dried-flower bundles. Seed heads and branches from your own garden cost nothing, once you've identified them.

Ornamental gourds you mean to eat later. Buy eating squash instead. It looks just as good, and you can cook it afterwards.

Fresh pumpkins too early. A carved pumpkin left out for weeks turns mouldy. Carve close to the day.

Real candles in a home with pets. Battery lights last longer and can't start a fire.
