Welcome to THE POISON GARDEN website
...because every garden is a poison garden.
The purpose of THE POISON GARDEN website is to provide insights, many of them amusing, into the human race's long relationship with substances that have the potential to cause harm.
Since the beginning of June 2011, I've been writing a blog
about poisonous plants, especially current news stories when a plant

But, before going any further, it's important to understand that accidental plant poisoning is very unusual and only very rarely do people suffer serious harm. Death from accidental ingestion of a poisonous plant, in its natural state, is exceptionally unusual.
I'm John Robertson and I've spent over ten years researching, writing and talking about poisonous plants.
Most visitors to this site are looking for information about a specific plant. The menu on the right will take you straight to a plant's page.

This site is not intended to be an exhaustive guide to all poisonous plants and contains much information which is anecdotal. For a reference book on plants, in the UK, which might pose hazards to children, I recommend 'Poisonous Plants: a guide for parents and childcare providers'.
It cannot be said too often that poisonous plants cause far less harm than might be expected. In 'Accidental poisoning deaths in British children 1958-77' published by the British Medical Journal, Neil C Fraser reports on a total of 598 poisoning deaths of children under 10 years of age. In the period covered only three deaths were attributed to plants. Even this low number is overstated since one death was due to fungi and in one of the other two 'the role of ingestion in the child's demise is doubtful'. Thus there may have been only one confirmed plant death, with 'hemlock' being the plant responsible, in twenty years. Fraser's analysis makes it clear that medication, household cleaning materials and cosmetics pose a much higher risk than poison plants.
The number of cases of accidental plant poisoning is so small that very few countries trouble to keep any sort of detail track of incidents. In 1996, however, a paper appeared giving detailed information for Switzerland. Though it would be wrong to suggest that the results are entirely typical of the whole world, they do give an idea of how small the problem of accidental plant poisoning really is. More detail from the Swiss paper is available here.

But, this is plants in their natural state. It is when products are made from them that the trouble starts. Deliberate consumption of legal intoxicants like alcohol and tobacco cause many millions of deaths every year. Far more than those caused by the use of substances made illegal because of claimed dangers of using them.
Also of great concern are the 'natural' remedies which people take not knowing that they contain deadly poison. Plants in the Aristolochia genus, probably, cause more deaths than any other plant.
