Newbie Info

I am a newbie gardener and I know next to nothing about tropical plants.

I live in Belfast and would like to add a nice tropical and relaxing look to my back garden with some cool plants.

Can anyone give any suggestions to plants that will be able to withstand unpredictable outdoor UK weather?

 

What is an average winter like - temp wise?
And a cold winter?

Trachycarpus palms should be ok
Chamaerops palms
Quite a few bamboo species
Tree ferns (Dicksonia) - with some protection/fleecing
Fatsia japonia
Zantedescia & Kniphofia

Just off the top of my head
