alnwick poison garden sign There are many plants that can cause you harm, particularly from the sap or if they are eaten. At Alnwick Gardens, Northumberland a Poison Garden contains quite a few of these – and several had to have their own special licence from the Home Office to be on show! Many plants have medicinal qualities of course (and some otherwise poisonous ones are used in medicines- Foxgloves and Yew, for example). But there is a fascination with the dangerous ones. As the creator of the Poison Garden, the Duchess of Northumberland, says:

‘I wondered why so many gardens around the world focused on the healing power of plants rather than their ability to kill… I felt that most children I knew would be more interested in hearing how a plant killed, how long it would take you to die if you ate it and how gruesome and painful the death might be.’

Pretty but poisonous- part of the Poison Garden at Alnwick Gardens

The garden contains over 100 plants with varying degrees of deadliness. It’s difficult to tell if a plant is harmful from it’s look, as some are beautiful while others look pretty harmless. Many of the plants grown in the Poison Garden are easily recognised as common to the back garden; Foxgloves, Belladonna, Poppies, Laburnum and varieties of Aquilegia for example.

And the nasty things they can do to you are many and varied. Eczema is a chronic inflammation of the skin and causes itchiness. Sometimes this is caused because the victim has an allergy to a particular plant substance. However, serious poisoning from plants in the UK is relatively rare and many plants can be grown safely provided they are treated with respect (and usually wearing gloves).



Younger children under the age of six who are able to walk have an increased risk of poisoning, because they often put things in their mouth without realising they are harmful. Also, as their bodies are smaller they are more vulnerable to the harmful effects of certain substances.

Poisonous plants cause far less harm than might be expected. In ‘Accidental poisoning deaths in British children 1958-77’ (British Medical Journal), Neil C Fraser reports 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 – one death was due to eating fungi and in another of the three cases eating the poisonous plant was doubted as the cause of death. In the one confirmed plant death Hemlock was the plant responsible.

The report makes it clear that medication, household cleaning materials and cosmetics pose a much higher risk than poison plants.

But illness, injury or irritation can of course be more frequent unless care is taken. The following is a list of some common ornamental plants that are either poisonous and/or a skin/ eye irritant, so remember they should not be eaten and cover your skin for protection if handling them:

Acalypha – Aconitum – Actaea – Aglaonema – Alstroemeria – Anthurium – Arum – Asparagus – Calla palustris – Capsicum annum –  Chelidonium majus –  Chrysanthemum – Colocasia esculenta – Datura – Drancunculus – Euphorbia – Fremontodendron – Helleborus – Heracleum mantegazzianum – Iris – Laburnum – Narcissus – Phytolacca – Primula obconcica – Solanum pseudocapsicum – Spathphyllum –  Tulipa –  Zantedeschia

More examples of poisonous plants can be found on the Royal Horticultural Society’s and other websites listed below. If you think you or someone else has eaten part of a harmful plant, seek medical advice from a hospital Accident and Emergency Department immediately, taking a sample of the plant with you. Do not try to make the person sick. Likewise if a pet has consumed something you suspect is poisonous seek veterinary advice as soon as possible.

Rethinking Childhood

Rotterdam child-friendly city report cover

Rotterdam is one the few big cities that has taken seriously the goal of becoming more child-friendly. Its ambitious planning policies have been debated in the National Assembly for Wales. Its public space improvement projects have been lauded at international conferences (indeed in 2008 it hosted Child in the City, a leading global cross-disciplinary event).

What is more, unlike some other Child-Friendly City initiatives, it focuses on hard outcomes that make a real difference in children’s lives – better parks, improved walking and cycling networks, wider pavements – and not just on participation processes that, however well-intentioned, may end up being idle wheels.

PicPost: Great Garden @ Hyde Hall

‘A visit to the 360-acre Hyde Hall estate is unforgettable in any season and allows visitors to immerse themselves in nature.

Hyde Hall is in an area of Essex that has very low rainfall, and this factor, combined with the soil conditions and exposed nature of the site, makes it a challenging area for gardening.

A visit will show that by choosing the right plants for the right places and by working with the prevailing conditions, it is possible to create a garden of beauty.’

My Botanical Garden

Ljubljana marketplace on a Saturday before Palm Sunday gets so much colour that it is impossible to skip it. Unique tradition arouse from the old habit to decorate homes with early spring greenery representing palm branches.So called BUTARICA is in Ljubljana region typical, made of some greenery and coloured shavings.One has to buy new butarica each year, at least one , to decorate Easter table and then to keep it as a decoration.I love the pre-Christian roots of this habit, when in pagan times first green branches were kept to burn them later in the summer for better crop and good health.How much power did our ancestors see in first spring leaves and how little do we respect the green branches today….that is why each year come to buy at least one butarica for my family…

Palm Sunday is a Christian moveable feast that falls on the Sunday beforeEaster. The feast commemorates Jesus’ triumphal…
