You(as a novice) have no control over when the plant blooms. Depending on what area of the USA you live there are several places that can provide them.

If you like a tropical rainforest theme with lots of greens and red, you may want to consider heliconia cut flowers arranged with lots of big green leaves. Heliconias produce both upright and pendulus bracts so it's more flexible for arrangement purposes. You could still use the bromeliads to line the lower part of the arrangements.

The wedding isn't until June 2010 and you've got your dress already? You're scaring me a little. ;-)

That's okay, it's good to plan ahead, but I would NOT try to grow the plants yourself. I suspect what you are referring to as "generic" bromeliads are certain commercial Guzmania hybrids. Not the easiest thing for anyone outside of a semi-tropical environment to propagate. Also you'd need a lot of greenhouse space for that many, and as HDD says, you wouldn't be able to time the blooming unless you had some experience with applying commercial flower-forcing chemicals. Best to leave that sort of thing to the professionals.

I like Lyndi's idea of using cut heliconias. There are lots of different varieties and they give a really tropical look. Red ginger is another good candidate, and anthuriums could be added to the mix too. Dendrobium orchids are very suitable for weddings. They don't come in red, but you could mix in some white ones if you don't want to use purple. You just need to find a florist in your area that has some experience using tropicals and can bring in a shipment for you.

Lol, actually my wedding dress is from a previous engagement that ended 2 months before the wedding date. I just love my dress so I kept it, not including the fact that i wouldnt get back what i put into it anyways.

Yes, lyndi's idea was very helpful! I didn't think tropical flowers could be cut flowers and I quickly did some research on them. I haven't looked up the plants you mentioned in google images yet but I will! I am getting a head start this time simply because last time I was about to settle for red roses instead of what I really wanted, which was this tropical rainforest theme. It is very over-whelming. I found a website that provide cut tropical flowers, but I'm afraid of what the mail would do to them, not counting the cost of $5 a cut flower... so several flowers in bouquets, decorations, and generally all over the place may not be as possible as I would like it to be. =) We will see though. I might throw in a lot more greenery plants. Would getting a mist machine be cheesy do you think?

I am glad my suggestion is of some help to you.
The Tropical Theme calls for a lot of lush foliage. Other suitable foliage/plants you could use includes licualas, palms, musas and alocasias so you don't have to buy that many cut flowers.. You could also use costus and alpinias. Create a few focal points like putting a few large arrangements at strategic locations. You could use terracota urns or pots to hold your floral arrangements. Hope this helps.
