You may or may not know about flower arranging frogs. They have been around for a LONG TIME. Over the years they have changed a bit. Typically what you can buy now is a heavy round base with lots of nails sticking up. The frog goes on the bottom of your vase or container and you stick the flower stem ends into the nails. The nails hold the flowers in place, exactly where you want them to go. A very old fashioned frog, you may be able to find at garage sales, is a glass round base with holes in it. It works similar to the nail frogs, except you put each flower stem into one of the holes in the glass frog. Martha Stewart has dedicated pages in her magazine to frogs and the different varieties and how to use them. If you are using a frog, you don’t have to use floral foam. So it is a way to get your flowers to do what you want them to do without using floral foam. They work the best in a clear glass vase where you want to see the flower stems. The frogs come in different sizes and are always weighted. This is so they stay at the bottom of the vase or container.
If you are trying to put flowers in a vase under water, it is imperative that you use a frog or the flowers will float to the top of the water!
