Wow, the amazing RHS Chelsea flower show! But did you know some flowers are poisonous to dogs?

Updated: Nov 5, 2018

The RHS Chelsea Flower Show really is magnificent with so many beautiful flowers and inspiring ideas for making your garden a place you want to be in this summer.

The colours and creativity really are amazing, inspiring me to take a look around my garden (more of a meadow with all the daisies we have to be honest!) and want to make a change.

But what flowers are safe for us dog (and cat) lovers. Our eldest is an absolute pickle, and will literally pluck the flower heads from all my flowers I've planted in one mamouth munching session; I think she may have been a deer in a previous life!

There's so much information out there about what is toxic to our beloved pets and lots of ideas about what we can plant and how to make it all look amazing. It's worth doing your research to make it ultra safe for them so we can truly relax and not worry about what the dogs are munching on while our backs are turned or if we dared to pop inside for a quick wee without them!!

Here's a few of the most common garden flowers and how they might make you pooch poorly.

Autumn Crocus

The Autumn Crocus can cause an intense burning sensation in the mouth, vomiting, diarrhea, seizures, liver and kidney damage, and even heart arrhythmias. Although the entire plant is considered toxic to dogs, the toxicity is highest in the bulbs of the plant.


Ingestion of just a few leaves of Azaleas can cause oral irritation with subsequent vomiting and diarrhea in dogs. In severe cases, ingestion can cause a drop in blood pressure, coma, and even death.


Although the entire plant is considered poisonous to dogs, it is the Daffodil bulb that is the most toxic. Ingestion of any portion of a Daffodil can cause vomiting, diarrhea, abdominal pain, arrhythmias, convulsions, and a serious drop in blood pressure.


Although the entire plant of a tulip is considered toxic, it is the bulb that is the most poisonous to dogs. Ingestion can cause significant oral irritation, excessive drooling and nausea.


Also known as the Mother-In-Law plant, the Kalanchoe is a common house plant with small dense flowers. When ingested it can cause vomiting and diarrhea. In rare cases, heart arrhythmias can occur from a poisoning.


Also known as Sowbread, the Cyclamen is a common household flowering plant with poisonous properties (i.e., terpenoids) to dogs. It can cause oral irritation, vomiting, diarrhea, heart abnormalities, seizures and death.


Especially popular around Easter, the lovely Amaryllis is also poisonous to dogs. Its toxins can cause vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia, and tremors in dogs.


Gastrointestinal tract and nervous system affected by plant toxins. May cause dermatitis.


The leaves and seeds are the poisonous bits on this one. Digitalis species is toxic if eaten, causing nausea and vomiting.

The Lily

There are many species of lily, here are a few common ones that are harmful.

Lily Lilium species Harmful if eaten in quantity.

Lily of the valley (leaves, flowers, roots) Convallaria species Toxic if eaten, causing nausea and vomiting.

Peace lily Spathiphyllum species Gastrointestinal tract affected. May cause dermatitis.


The pods and seeds of wisteria can cause repeated vomiting, stomach pains, severe diarrhea, dehydration and collapse.

The Dogs Trust have a brilliant, very comprehensive list of not just flowers and plants but also other household things that are harmful to dogs, check it out here. Obviously, if you think your pet may have eaten something they shouldn't have, the best advice you can get is from your vet and as quickly as possible.

There are so many lovely plants from this beautiful world we live in that we can plant in our outside areas but still keep our furry friends safe. Enjoy the designing, planting and viewing and fingers crossed this lovely sunny weather is here to stay!!
