Since your new, a good idea is to get aquainted with the documentation
Particularly, have a look at the Working with Vector Objects, Creating Basic Shapes section.
I think that what I see is a special font used + a vector object (the leaf).
The tools in Fireworks are relatively easy to use and very intuitive, so if you have the font and have a bit of understanding how vector tools work in Fireworks, this will be very easy for you to replicate.
Try also these resources:
http://www.adobe.com/devnet/fireworks/ -- lots of useful tutorials.
http://www.fireworksguruforum.com/ -- very helpful community of Fireworks gurus, lots of great tutorials (also see:
http://www.fireworksguruforum.com/index.php?showtopic=7972 -- list of selected tutorials)
-- two long lists with tutorials for beginners and advanced users, published in SmashingMag.
http://www.fireworkszone.com/ -- lots of useful stuff here, too.
Hope this helps you!
