Yes - Phormium. One of my Yellow Wave ones is about to flower any moment. I've just divided some of mine. The common or garden ones get very big - I had the green one which flowered regularly (as in your pic Panda) but they do need a bit of room to look their best. Lots of good named varieties which tend to be a bit smaller but they're great in containers too.
If you want a piece of Yellow Wave - green/yellow, or Blackadder - very dark plum, let me know
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
Erm, yes please Fairy The black adder one looks amazing (although, to be fair, so does the Yellow Wave!). I know where I could put it too so it has loads of room
Phormium grows from seed Chrissie but it's a long time before it's like Pandas photo.The cultivars won't come true but everything comes from seed except sterile hybrids
I had an enormous Phormium tenax, one of the 2 very cold winters was too much for it and it died in a very rotten smelly way. I may start another one if I can think of somewhere to put it

Thanks everyone
Bob, done some googling, I think the others have it I'm afraid
i might have a go at collecting seeds myself Fidget
It is huge and very lovely. God knows where I would put it in the garden 
They take a long time to get huge,except in Cornwall.
Lol snoodle
I've seen them in gardens Panda, think they are lovely too. Good luck with the seed collecting
I don't know that Hesperaloe but I'm glad you introduced us to it Bob
Nut, it would be perfect for your garden http://www.tropicalbritain.co.uk/hesperaloe-parviflora.html
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
I have one of these flowering for the first time, it is definitely a Phormium. Don't think it will grow from seed

I just have the bog standard phormium and it is a whopper flowers aren't even attractive, might be going to plant heaven soon.
No prob Panda. PM your address and I'll send some bits to you. They grow on very easily.
