A poisonous flower known as the devil's helmet has been blamed for the death of a gardener in Hampshire. What other plants should you look out for?
The news that a gardener in Hampshire collapsed and died of multiple organ failure, apparently as a result of handling aconitum, or aconite, known as the "queen of poisons" will no doubt have worried many.
According to Elizabeth Dauncey's book titled Poisonous Plants, there are usually up to two fatalities a year from plants (mainly caused by yew and hemlock), but these are mostly suicides.
Otherwise the most reported cases (but not fatalities) are from cuckoo pint (the seductive berries), laburnum, daffodil bulbs, and woody and black nightshade. Apparently with daffodil bulbs, people mistake them for onions, when stored in a potting shed, for instance. In a stew they add a rather strange taste and can make you sick. If you are frail, they might kill you.
Nightshade berries decrease in toxicity as they ripen and they have a bitter taste; they are certainly not ones to gorge on. In 1992 hemlock water dropwort growing wild (the foliage is similar to celery) did kill two foragers.
Another interesting, unsubstantiated, case is of cherry laurel leaves being taken to a tip by car and the driver being overcome by cyanide fumes given off by the foliage. According to Elizabeth, a leading plant toxicologist, this is feasible if you had a large amount and left them to allow cyanide levels build up, and drove for some time. All of this highlights the need to know what you grow and eat.
