Tillandsia cyanea?

Also known as "Pink Quill". As you may know, Pineapples are also bromeliads.

Yep. Genus Ananas

I have the same tillandsia, and here's how it looked last October

I bought it more than two years ago, and it did not rebloom the first year I had it, but then two years later it made more flowers. Don't give up on it if it does not bloom the next year, as it may require time to adjust to its new environment. I keep mine in my pergola, where it can get good air circulation, and I potted it in bark, although I think it will grow without soil, being a tillandsia. Just make sure it gets plenty of air and keep it misted.

Look at steiconi's topicposted "A hairy fence". T. cyanea can get much large if potted up as it grows. I haven't potted up mine all these years from its 4" pot because I thought they were small plants. Stei's were awesome.

Does this die after flowering?

Mine did not die after flowering and flowered again two years later, but I believe that the old growth eventually dies off, after the new growth has started.

And does it need the vase filling with water, or am I ok to just mist it (its kept indoors?

It is an "air" plant, and so it should not sit in water but should be misted at least twice a week, depending on how dry your air is. When the humidity is high, I do not mist mine that often, but when it is very dry, I sometimes mist it every day or every other day. I've never grown any indoors, and so I'm not much help with that.

Thanks Lars. Thats what I thought.
