Are these 2 giant's Cordyline's?

No, they're Phormiums. They spread sideways through the soil and don't form a woody stem. You can dig them up and split them if they get too big.

they also flower too. mine has thrown up a flower spike, the first one in its 8year life. cant wait to see its colour.

Ooooh thanks again, you're both such stars! Maybe there's hope for them yet Sbg?

I've never seen one in flower either, can you put a photo up when it comes out?

Bamboo, I certainly will if and when it does! Oh, or are you asking sbg? hehe!

Not too far from where I live is a block of flats and they have two massive phormiums which seem to flower every year. I have only seen them in passing, but the flowers appear to be about 10 to 12 feet high. I haven't been that way lately and they're possibly a different variety from yours. I always think phormiums are much gentler than cordylines as they nearly poked my eye out a few times, and even though they were beautiful, I was quite glad when a severe frost finished them off!

Haha! I would be sad if these died, tho', I wouldn't know what to replant them with!!!

i will do a picture if the flowers open.

Hi folks,
These are Phormium tenax and the flowers will reach up to 7 or 6 ft. on a mature specimen (here). The other species, P. cookianum, is smaller but still quite a large plant. If you really want to get you eye poked out, Born, try Yucca gloriosa, you would need a suit of armour to get near it (but the flowers .....mmmmm)

Thanks Sbg!

Oh, thanks for that Vincent! I've written this down in my trusty notebook!
