We’ve got a lot of these growing along my local hike, and I love the idea of planting native species in my garden - any idea what they are and can I take cuttings or something to plant them in my garden?
They look lovely in vase too - I brought these back from my hike yesterday 
Fireweed?
It is known in North America as fireweed and in the British Isles as rosebay willowherb
Nice one Alice!
I think I prefer our name, Rosebay Willowherb
On occasion I have walked past them and there is such an amazing fragrance coming from them (or something near them). I wonder if certain flowers emit strong fragrance at certain times?

Making Fermeted Tea With Rosebay Willowherb
Nice one Alice, I might try making the tea one day 
Fresh Rosebay Willowherb shoots can be cooked and eaten like asparagus
We have Fireweed but it is toxic to animals and a weed from Africa. Looks quite different to yours. I am constantly pulling it up.

Poisonous to horse and cattle.
