Giant redwoods: largest trees 'thriving in UK' (2024) (bbc.co.uk)

I absoluetly adore Giant Redwoods.

Obigitory link to https://www.redwoodworld.co.uk/index.html

for an index of where to find some of them.

Because Sequoiadendron giganteum requires forest fire, producing a self-sustaining forest in the UK seems a particularly hard row to hoe.
