Poisonous Plants
I’ve been doing a little gardening in this fantastic February weather and bought some seeds online to grow indoors. When I was checking out the seeds I was amazed to see just how many poisonous plants we have in our gardens.
The Lupin seeds I was planning to sow had a poisonous warning on the packet, so sadly I can’t use them because of my dogs. Interestingly, the Sweetpea seeds didn’t have a warning, but they are on this list!
I recommend researching any plants that you intend to buy for the garden if you have children and/or pets to check if they are poisonous plants. Also, have a look to see if any of the plants you already have are on the list.
I have compiled a list (in alphabetical order) of the most commonly known poisonous plants. I only picked out the ones that I had heard off, and I am a complete novice! There are many, many more.
Obviously, the level of toxicity differs in each plant. Some are only harmful if eaten in large amounts and others may just have parts of the plant which are poisonous (eg bulb, seeds, flowers)

Don’t forget that plants have some amazing health benefits too.
Also, most of these poisonous plants aren’t harmful unless you eat or digest them, so there is no need to make radical changes.
If you have dogs, it is well worth checking that plants are safe before you buy them. I was once horrified when my dog Alfie ate a whole tub of marigold flowers just a few minutes after I planted them. Luckily he was absolutely fine!
There are also reports of people falling ill after mistaking daffodil bulbs for onions.
Common Poisons Used In Crime Thrillers
Shakespeare used Yew in Macbeth, he added it to the witches cauldron.
Agatha Christie also used Yew in A Pocketful of Rye, it was added to a jar of marmalade to disguise the taste.
Another Agatha Christie novel where plants were used as poison is Five Little Pigs. Poirot investigates the use of Spotted Hemlock hidden in a glass of beer.
In A Carribean Mystery also by Agatha Christie, Belladonna is placed into face cream
