Thanks people! No conclusive winner out of the bunch, but it was narrowed down to 4.

So I just wrote the numbers on pieces of paper, folded them up, tossed and picked one. :whistle: I hope she likes.
Oh and yeah, it's for Vday.
Not to be rude or anything, and please forgive me if it sounds rude, but if is for a 'girlfriend" and especially on Valentine's day; these type of mix flower arrangements is not the right gift to give to your girlfriend. But is nice for your mother, a co-worker, friends etc. If is different occasion beside Valentine's it will be wonderful though.

UNLESS you knows for sure that she like mix flower arrangement.
If you still wanted to go with mix flower arrangements like those in the pictures above, instead of having vase arrangement, ask for it to be arranged in a bouquet style, similar to a wedding bouquet, but with longer stems. Also use a nice Valentine's theme ribbon and lots of wide-wire and paper ribbons. And if you still wanted the vase arrangement, have them wrap the vase separately with pretty gift wrapping paper so it looks like you have giving her two gifts instead of one. It'll also shows that you're thoughtful enough to think of getting her vase for her bouquet. ^_^
Be simply and thoughtful, not just pick out anything that is pre-arranged or from the shop catalog.
If you don't want to spend too much money you'll be better off with half a dozen of roses arrangement or just few stems of her favorite-favorite flower or just a small vase arrangement with 3 roses with a nice card and a nice sweet treats will make her happier.
But is all up to you, is a thought that count so good luck. ^_^
