Tillandasia not flowering

Hi there could anybody help perhaps, I have been growing my airplant (t. Bergeri) to my knowledge as its the only one in shape and growth habit that comes close) from 2000 got a cluster from a neighbour... It has grown in almost every possible position, exept the darkest of shade and not indoors has always received a good soaking less in winter more frequent in summer but not once never ever even slightly showed a need or whim of the intent to flower. Pups galore if I have to put all the babies together and 're-unite' the entire lot it will be a huge bush. Why doesn't it flower or does it just not flower? According to pages I have googled 'all tillandasias flower' and if so I want to know why this one is just not in the mood to lol.

IF the plant is having pup's / babies, then I think there is every likelihood the plant has flowered and been fertilised by a mail plant close by or maybe these are both sexes on the one plant, but babies do mean some form of flower.
I don't know anything about the plant you have to be honest so maybe IF you look on the site for Bromeliad's or even air plants on the list of forums or maybe someone else can direct you there.
All I do understand is that this is a large family of plants and normally as flowering time approaches, the leaves can change colour, normally around spring early autumn time, after flowering, the leaves then go back to normal colours, the bract's and flowers can be on the same plants depending on the type of plants. believe it or not but the Pineapple is from the same family.
hope this is helpful and others will come in for more info than I can give you.
Good luck and best regards. WeeNel.

Thanx Weenel, I know of the Pineaplle plant (that will be a new project I would undertake as soon as spring arrives) getting it to grow from a crown, I love broms, have 2 other a Billbergia Nutans aswell as a Cryptobergia, and trust me hehe if my Tillandasia flowered I would ve noticed as I always supervise my plants daily as for the 'pups' the T. Bergerii 'branches' its not like your ave. Brom when after producing its flower spike it produces its pups. (That's what I meant with the pup/babies part) Broms make pups without having to be fertilized, they have a rhizomatus growt habit ,its when you want to reproduce them from seed that that whole male female shiznizz stuff gets working and that is waaaaaayyyy to much time and effort trail and error if I had the time , could be fun but currently I would not be able to give that type of detailed attention. I'm not subscribed and this forum seemed like a good starting point, there is so many gardeners out there I had to atleast try, I'm a curious person and if something is elluding me and other sources give only general information, who knows somebody should know some where, yet again thanx for atleast trying I appreciate :-) can't seem to upload an image here will try and post it in my Journal

Just keep checking Gaiana, maybe someone will still pick up the thread you sent onto the site, I think there are several forums that you can go onto without membership but to be honest, you will meet people from all over the globe here on the site and everyone is very friendly, I'm not an expert by any means but I do believe you can take out a 3 month trial membership so maybe you could give it a go. hope so as you will learn all about other plants you never heard of but can probably grow in your area.
Have fun and happy planting. Kindest Regards WeeNel. UK.

Many bromeliads need ethylene gas to promote flowering.

If you have a spare pup or two that is large enough to flower (fairly mature) then try this:

Put it in a plastic bag, just like it is in a greenhouse, and add a bit of banana peel. As banana peels break down they release ethylene gas, and this may promote flowering. You might have to change out the banana peel every few days.

Great tip Diana, I sometimes drop a Banana peel into the compost in my large pots that have larger plants growing in my conservatory, it helps give the plants a little boost, or wakeup call when looking a bit sullen LOL.
Best Regards. WeeNel.

Mmm I think that I'll try the banana thing I eat a lot of bananas hehe so that sound like a good Idea... Have heard of this method quite often but never really thought it could work for a tilladasia but def going to give it a go thanks :-)
