Situated at Alnwick Castle, in Northumberland, is the Poison Garden. The plants within are beautifully kept and marked with warning signs, adding to their allure.

Despite the dangers, this poisonous garden is a popular tourist attraction. Visitors are able to get up close to the plants but are not allowed to touch them. The garden is open from April to October, and entry is included in the price of admission to the castle.

Here’s a guide on how you can visit the Poison Garden.

The Poison Garden in England

Alnwick Poison Garden Need-to-Knows

The Poison Garden at Alnwick Castle is one of the most unique and intriguing gardens in all of England. This garden is filled with over 100 species of poisonous plants from all over the world. 

Where in the UK is the Poison Garden?

The Poison Garden is located at Alnwick Castle in Northumberland, United Kingdom. This region borders Scotland and sits in the northern part of England.

It’s a stunning region with stretches of coastline and gorgeous green landscapes. From London, it’s about a 5-hour drive north.

How Much Does It Cost To Enter The Poison Garden, UK?

Admission to the garden is included in the price of a ticket to Alnwick Castle. A standard adult ticket costs £19.50 (about $25). This ticket allows you to visit the castle and its grounds anytime from 10 am to 3:45 pm, and you won’t have to leave until 5 pm. 

Poison Garden Plants

Included in the ±100 plant types that grow in this garden are some that will instantly kill anyone who ingests them.

Others may just cause discomfort if ingested, and some are dangerous even to touch. But there are a small few that release dangerous fumes as well, so you really need to be alert here. 

Poison Plants in the Garden

Not to scare you, but many of these plants grow freely across the UK, in the wild, and even in some home gardens. People aren’t always aware of the dangers of these plants, which is why the Poison Garden is actually a fascinating, educational landmark. 

Some of the most noteworthy plants in the garden include: 

  • Monkshood – Also known as wolfsbane​​, this plant is incredibly dangerous, becoming fatal to those who simply touch it. It’s beautiful, but don’t be tempted to cradle those dainty blue flowers. 
  • Laburnum tree – This is one of those poisonous plants that is often seen in gardens around the UK. The golden chain, as it is also known, can cause nausea, vomiting, and death if the seeds are ingested. Dogs should not be allowed to play with the branches from this tree either. 
  • Castor oil plant – Even though we use parts of this plant for castor oil, there are parts that can make you really sick — or even kill you — if they enter your body. The plant contains the toxin ricin, and if it gets into your mouth or eyes it can cause a whole bunch of horrible effects. 
  • Angel’s Trumpet – Not only can this plant cause hallucinations, paralysis, and memory loss when ingested, but it can be fatal in large doses as well.
