Hidden Garden Dangers for Cats & Dogs

Recently I mentioned that we want to start planting flowers and the like in our garden. I mentioned how I would like some foxgloves and delphiniums – lovely flowers! However, I’ve now found out that they’re dangerous for dogs! As our dogs eat EVERYTHING then I’m going to really have to rethink what we plant out.

Hydrangeas - who knew they were toxic to cats & dogs?

Hydrangeas – who knew they were toxic to cats & dogs?


More Th>n recently teamed up with to Ian Drummond to create the World’s most dangerous garden for cats and dogs to raise awareness of how dangerous common garden plants can be.

Some Statistics

According to research:

  • 78% of British gardens contain plants that are toxic to cats and dogs.
  • One in three pet owners (31%) admit they have no idea if the plants and flowers in their gardens are toxic to pets.
  • 4/5 household gardens contain toxic plants
  • 10% of cats and dogs have ingested poisonous plants or flowers with 43% of those needing urgent veterinary care with 15% sadly passing away.
  • Most dangerous gardens are found in London & South East  (83%), Wales (80%), South West (79%), East Anglia (78%) and the West Midlands (77%)
  • 71% of pet owners cannot identify any symptoms of poisoning in their pets

(above statistics have been taken from More Th>n’s press release)

MORE TH<N’s Pet Safe Campaign

The following has also been taken from More Th>n’s press release


The findings come as MORE TH>N launches a new Pet Safe campaign to raise awareness of the issue of cats and dogs being poisoned by common household plants and flowers – particularly timely given that pets are likely to spend more time outdoors over the next few months due to improving weather.


To kick start the campaign, MORE TH>N has commission RHS Gold medal winner, Ian Drummond to create the world’s most dangerous garden to cats and dogs.   Launched at the Horniman Museum and Gardens in London at the beginning of June, the garden will be taken to different locations throughout the capital by the charity Core Landscapes.


Far from being rare and exotic botanical specimens, all of the plants and flowers can be found in any home garden, public park or horticultural centre in Britain. A few of the plants on show include: Begonia, Buxus Pyramiden, Chrysanthemum, Clematis, Cordyline, Daisy, Dahlia, Elderberry, Foxglove, Grape plant, Hydrangea, Hedera Ivy, Lilies (variety), Cherry Laurel, Marigold, Nerium Oleander, Paeonia mix, Papaver Poppy, Tomato plant and Wisteria.


According to vet and consultant on the garden, Robert White-Adams, “As a nation of animal lovers we’ll do anything to not put our pets at harm. What this campaign reveals is the hidden dangers many of us wouldn’t even be aware of. Each plant has been chosen to show just how many common varieties can make our pets ill, or worse still, die if not treated immediately by a vet.”


In addition to raising general awareness of this issue, MORE TH>N is directly campaigning for plant producers, manufacturers of garden products and retailers to provide clearer labelling to help pet owners easily identify if items are safe or harmful to cats and dogs – something that 86% of cat and dog owners would like to see. For more information on the campaign petition please visit www.morethan.com/pet-insurance/news/most-poisonous-garden.


John Ellenger, Head of Pet Insurance at MORE TH>N, commented: “The MORE TH>N Pet Safe Campaign allows us to raise awareness of the dangers of plants that are poisonous to cats and dogs in an imaginative and memorable way. However, our new campaign is also about taking direct and immediate action – by both urging suppliers and retailers of garden plants and flowers to provide clear ‘pet safe’ labelling, while also better educating pet owners on the issue.


“Through this campaign we’ll be arming pet owners with the practical advice and information they need to identify safe and dangerous plants, to recognise the symptoms of poisoning – and what to do in that eventuality – and above all to reduce the likelihood of their beloved pets becoming ill in the first place.”

Pet owners can also win free pet friendly flower seeds via MORE TH>N’s social channels; www.facebook.com/morethan and www.twitter.com/morethan.

So what common plants are toxic?


I actually have a purple version of this ready to be planted!


What I found most interesting is the list of common toxic plants – some of which we were planning on planting such as lillies, foxgloves, daffodils, and delphiniums. Common Toxic Plants include:

apple seeds, asparagus, begonias, bluebells, crocus, delphinium, foxgloves, hydrangea, ivy, lillies, lupins, oak (acorns), primrose, potatoe (sprous/vines), rhodedendron, snowdrops, tomato plants, wisteria

Symptoms of Poisoning

So how do you spot if your pet has been poisoned? Here are some symptoms to look out for. If you see any of these symptoms in your pet then contact your vet immediately as it could be a matter of life or death for your beloved pet. If possible take a sample of what your pet has eaten as that might help the vet to diagnose and treat your pet.

  • Oral or skin irritation
  • Upset stomach / Vomiting / Diarrhoea
  • Weakness
  • Rapid breathing
  • Fever
  • Drooling
  • Coma
  • Heart failure
  • Excitability or lethargy
  • Tremors / Seizures / Fitting
  • Increased Thirst
  • Dilated Pupils
  • Dizziness / Loss of Balance
  • Disorientation

Hopefully this post was useful – I know I found this information useful and like I say, means I now have to have a rethink of what to do with the garden.

    I planted a poisonous plant (passion flower) in the garden knowing is poisonous for dogs. I have a dog, but he will never eat from it. I know it can be an issue if we want to sell or rent the house as I would, obviously, disclose that.

    My mother sent the seeds by post (she is 3,000 miles away) and we’ve planted them in a pot, it grew so fast that now is in the garden and it’s doing great.

    I fully agree with you, unless you are 100% sure the dog or cat will not eat it, don’t plant it.

      I didn’t even think of it being an issue if selling but that is a good point!

      Our dogs eat eveyrhting so we’re going to have to research for sure!
