The Datura plant

When you walk on the riverside walk in Formentera the gardens are a pleasure they are well maintained by the council and have a great variety of shrubs and plants, The Datura is nice to look at but dangerous to touch, as it is very toxic and will cause delusions and hallucinations if ingested. It is a woody-stalked, leafy herb growing up to 2 metres. It produces spiney seed pods and large white or purple trumpet-shaped flowers that face upward. Common names are Jimson weed, Hell's Bells, Devil's weed, Devil's cucumber, angel's trumpet and devil's trumpet.

Poisonous Oleander

The Oleander(Nerium Oleander)shrub is a very popular plant around here in public garden areas and parks and as a potted patio plant, it is very drought resistant and flowers prolifically with five petalled flowers on long stems,in red, pink and white colours. By removing suckers at the base of the plant, and leaving just a few stems, oleander can be formed into very attractive small trees.
What must be remembered is that is very poisonous, even the the smoke from burning the cuttings and wood are toxic, it has been known that people using the wood on a barbeque have poisoned themselves.
