The foxglove comes from Ireland
Some poisonous plants that can be found in Ireland include foxglove, deadly nightshade, and hemlock. It is important to be cautious and avoid contact with these plants, as they can cause harm if ingested or touched.
Ireland is particularly associated with the colour green. As Ireland is on the edge of the Atlantic, it gets a lot of rain, so grass grows easily in Ireland, along with trees and other plants. So there is plenty of green to be seen in Ireland...
Maple tree, sycamore tree and the oak tree.

Lots of things will not grow in Ireland, due to the climate in Ireland. So there would be a huge list. Almost anything that grows in very dry or hot climates will not grow naturally in Ireland. They could only be grown in special greenhouses designed for such plants. So things like banana trees or orange trees would not grow naturally in Ireland. Grapes would be difficult to grow in Ireland. Many other things would not grow, like tea or coffee plants or rice. There are far too many things to list.
