Wedding centerpieces/orchids - help!!!?!?

I am getting married in August and the reception is in an outdoor/indoor high peak tent. Since the ceilings are very high I bought eiffel tower vases, which are the tall skinny vases. I think they're 16". Me and my fiance met b/c of a trip to jamaica that we both happened to go on and we really want to incorporate jamaica into the wedding in an elegant way. I have quite a few ideas so far but I'm stuck w/ the centerpieces. I've seen alot of great ideas and tips on here but nonetheless - I want to use pretty much all white flowers, orchids, hibiscus, hydrangea..i saw this pic on google

They look like a mixture of orchids to me...but I am not positive.

You can try this website for fake flowers. They also sell the eiffel tower vases...so they may be able to offer you some ideas/accessories for your centerpieces.

Hard to tell exactly, maybe orchids, some willow...hmmmm Here's an arrangement in the small mouth Eiffel tower vase. Change the flowers to Orchids and some Stockflower and I think it would be very pretty. http://farm3.static.flickr.com/2355/2228...
