When you visit the site, you will see the bouquet in the middle with the flowers on the left. You can choose the bouquet and its color and also choose from a wide range of flowers to drag an drop into the bouquet. Here’s a sample bouquet which I created.

I sent the bouquet to myself and received the email almost immediately. The email had a link, which when clicked took me to the page which had the bouquet plus the greeting card (a tag rather) hanging onto it.

Hence it’s a hassle free, fun tool to send quick greetings.
