A British woman walking in the park was horrified to discover one of the most dangerous plants on the planet growing in a council flower bed, reports Wales online.
The woman found Ricinus communis, commonly known as the castor plant, to be 6,000 times more poisonous than cyanide. According to Media Wales, Conwy Council groundskeepers planted flower beds in Queen Gardens Park in Colwyn Bay earlier this week. The tree lies among the flowers and shrubs.
The castor plant contains ricin, a banned substance that, in large enough quantities, is considered a chemical and biological weapon. Although gloves should always be used when handling crops, seeds and seed heads pose the greatest risk if consumed. Just 1 to 10 seeds can be lethal.
Based on the Guinness Book of World Records, Based on the amount of poison needed to kill a human, the most common poisonous plant in the world is the castor bean (Ricinus communis). According to the Merck Index: Encyclopedia of Chemicals, Drugs, and Biology (1997), a dose of 70 micrograms (2 millionths of an ounce) is enough to kill a 72 kg (160 lb or 11 st 4 lb) person.
Follow Daily post,Conwy Council said it would take the usual precautions with the latest batch of Ricinus planted in Colwyn Bay and elsewhere.
A spokesperson said: “We have been using Castor Oil (Ricinnus communis) plants in our bed screens for many years and they are commonly used in bed screens across the UK.
“As with many ornamental plants, the seeds and seed heads are very toxic if ingested, and we seek to remove the plant before the seed heads form.” According to the Royal Horticultural Society, other flowers and ornamental plants, such as yews, bellflowers and canaries can be toxic if ingested – even daffodils.
