We designed these brass frogs to fit our new Ikebana vases, although they also work with other vases and containers including simple Mason jars. Throw out the non-biodegradable floral foam and add frogs to give all kinds of displays stability. Use the frog with the large single opening to help propagate your favorite cutting or to force a bulb or a branch to bloom (learn how-to in our journal article). Use the version with 3 openings to create simple Ikebana statements or to accommodate thicker stemmed species. Use the frog with the multiple openings to arrange flowers and botanicals. We prefer the natural beauty of letting brass age gracefully and do not apply a lacquer finish to these.
