For many of my layouts and cards, flowers grow in the floral department of craft stores. I often purchase flowers by the stem and then pull them apart using the individual petals or groups of petals on my papercrafts. I just completed this spread accentuated with a several silk petals. The light pink ones are paper flowers I had in my stash from a large scrapbooking kit I got from Sam's Club.
It is really easy. All you have to do is look for flowers you think will be simple to 'dissect' and still have usable petals. In these photos you'll see some hydrangeas and delphinium. Another good choice are the large daisies. I haven't found any good true white ones but I've bought many colors including an off white which is easy to stamp or ink the edges.
After removing from stemp, pull off the green part that hold the petals together.
My favorite accent for the centers are rhinestone brads. I've also used other types of brads and buttons. Don't be shy about layering different types of petals together for creative looks.
Pretty petals and you don't need a green thumb or a lot of green cash either.
