can somebody tell me which are considered more stylish flowers to send some one roses or tulips.?

Tulips are an original idea. Roses are more traditional. I would say go with something that is not only about them, but also says something about you. If you are someone that doesn't like to follow tradition, go with the tulips or you could choose another type of flower. If you are a traditional kind of person, go with the roses. This way it is also easier for them to tell that it was from you and you really put some thought into it. But I would also make sure I know what color the wedding party has chosen for the flowers. This way it could possibly make a nice addition to the wedding itself.

Roses

Roses can be given for any occasions, but tulip is something different.

isn't tulip season over already? Sending tulips might be a bit too expensive at this time of the year. Roses are too ordinary. Talk to a local florist for "what's in season" and then send a bouquet of that.

Stephanotis (genus name) commonly known as Madagascar Jasmine means happiness in marriage. I don't know what it is but the meaning is perfect. I'm sure a florist would know.

It is so pretty! it looks like jasmine, and apparently they use it at weddings allot.

Although both are beautiful, I would go with the tulips for an engagement party. Roses are more wedding and the tulips are very classy for an engagement.

it depends on the person, but since roses are more popular than tulips, i suggest you send TULIPS =)
coz it's rare and beautiful. and i think it fits the occasion

For a wedding i would definitely send Orchids. They fit more into the wedding theme if you will.
