We've just returned from a superb (if pricey) holiday in Alberta and British Columbia.
Whilst on Vancouver Island, we visited Butchart Gardens, about 10 miles north of Victoria (the provincial capital). The place is absurdly pretty, and has a small number of Giant Sequoias (Sequoiadendron giganteum).
They're apparently quite happy, albeit about 500 miles north of their natural range (they peter-out in northern California). I spoke to one of the horticulturalists, who puts their success mostly down to a relatively mild micro-climate. Here are a couple of examples:

Butchart Gardens: a pair of young Sequoiadendron Giganteum background, and a Sequoiadendron Giganteum Pendulum ("weeping Sequoia") left foreground.
"Wellingtonia" is the common British name for the same species, which was introduced here in the 1850s (the name was already assigned to a different plant altogether and "Sequoiadendron giganteum" wasn't finally settled on until 1939!).
Sequoiadendron Giganteum like the British climate, especially Scotland, although we had a couple in our back garden when I was a child in south-west Surrey, hence my particular interest in them. Ours were probably planted some time in the 1860s, and in 1970 easily 100ft tall. Sadly (more so as I actually climbed the taller of the two!), Google StreetView shows they were both felled, fairly recently.
Anyway, that conversation with the Butchart horticulturalist, and a rather poor article on Forestry England's blog were interesting. I knew fire was an important part of Sequoia propagation, and that the ones in their native range are in difficulties. In contrast, the ones here seem to be fairly common and thriving. I can't find information on how they are propagated, but they must have been!
Has anyone got links with tree nurseries that have grown them? I'd be very interested to know how they do it. We used to get lots of cones from our two trees, but they usually stayed quite green and firmly shut!

*Forest fires apparently prompt the cones to open and release seed, at the same time removing underbrush so young Sequoia can flourish - mature Sequoia have fire-resistant bark and usually a big gap (tens of feet) between the ground and the lowest branches. Human fire management has interrupted these natural processes, meaning the current generation of mature trees in their native California will probably die before any seedlings can reach a safe age (and height!) to replace them.
