Every rose comes with a card and code. As an example, if you order 6 roses you will receive 6 cards complete with an individual code (eg MR2525). This code is your personal code. As soon as you start handing out the roses, they will be forwarded and invite people to start their own campaign. When people respond to this offer, they not only receive their own roses and code, but also 2 roses with your code . As such, many roses may spring form one single rose.
