Very pretty, it's a Bromeliad, possibly Guzmania or Aechmea blue tango, but I'm not sure. There are hundreds of pictures on the web.

Thanks Cammomile - I will now be able to browse the web having a look - Bromeliads are a new world to me! Nina

Just had a quick look and it appears to be Aechmea Del Mar - I think I may have to buy one as it is so bizarre! The other bromeliads I have seen online are also quite amazing - perhaps a new area of interest for me! Nina

It's related to the Pineapple.

It could be a Portea. I have one with the same flowers and leaves, and identified it that way. If you do get it, remember that after it flowers, it takes around a month for the pups to emerge. The main plant will never flower again, and it likes bright light, but not sun (I grow mine in my woods). Also water (with just a touch of water soluble fertilizer) in the throat.

I think I need to do some reading before I buy one! Nina

It is Achmea Blue Tango del mar, Ninap... Check out Bilbergia nutans as well, that's a beauty in flower...

Thanks Bamboo - will do! Nina
