“The earth laughs in flowers.” – Ralph Waldo Emerson
Have some extra Valentine’s Day flowers laying around? We have the perfect use for them! There are many different crafts that we make with flowers – gluing them to crowns, making flower petal butterflies, or using them as paint brushes. In fact, flowers are a wonderful part of just about any nature craft; they add pops of color to nature weavings, mobiles and nature journals. One of the new ways that we have been using them recently is for their pigments. The most common plant pigment is chlorophyll, which is used primarily for photosynthesis. Other colors found in leaves, like reds and yellows, are secondary colors that also help absorb light energy. Flower pigments, the colors in the petals and sepals, are used to attract pollinators. Plant pigments are made out of a variety of molecules, including anthocyanins and carotenoids. While the biology of plant pigments is fascinating, it is also really easy to get them out of the plants themselves. So easy, in fact, that kids do it all the time (think grass stains). All you need to do is rub the plant against some fabric or paper and the pigments come right off onto the surface. With this in mind, we have being creating some fun crafts that use flower pigments as color.
A really fun way to get the pigments onto paper or fabric is by pounding. This can be accomplished in any manner of ways, but we like to use small stones. While a wooden mallet or small hammer will do the best job of evenly flattening the flowers, small stones are more kid-friendly. Specifically, we use flat, decorative driveway stones that are about 3 inches square or less in size. There is no need to hit the flowers hard; a gently tap will do it. Lay your flowers flat on the surface of your choice and place a small piece of white paper or fabric over the flower, then gently tap the flower all over with the flat of the stone. Remove the cover and peel off the flower; you should see the flower’s shape echoed in the pigment print.
The best paper to use for this project is watercolor paper. Unlike office or drawing paper, watercolor paper is thick and has dimples that will readily hold on to the flower pigments. We like to make bookmarks and picture frames out of our flower pounding projects, but the sky is the limit. If using fabric, unbleached linens and muslins will work best. Ideas for fabric include lavender sachets, cloth napkins and table runners. You will want to start with a white or cream base, as the pigments will not always be dark enough to show up on colored fabric or paper.
Pounding is a technique that can sometimes be difficult for younger children. In lieu of pounding with a small stone, flowers can be rubbed across the surface to produce a color. In this case, it is much more difficult to recreate the shape of your plant on the base. Rather, you will end up with smears of color. However, the sensory experience of rubbing flowers to produce colored pigment is a wonderful activity for small children. The scent, color and texture of a variety of flowers will be a worthwhile nature exploration activity, even if the results are not as polished.
Not all flower are pigmented equally…
While all flowers have some pigment in them, not all of them work equally well in this activity. Some petals are too watery or too thin and will not produce a good image. Test all your flowers on scrap material or paper before you put them on your finished product. We recommend pansies, chrysanthemums, goldenrod, colored daisies, and marigolds to start out. Additionally, leaves will add a lovely pop of green to your project. Like with flowers, stay away from thick, watery leaves. Explore your yard and local green-spaces to find a variety of colors and textures from your project. Or simply buy a bouquet of grocery store flowers – any flower and leaf has the potential to make beautiful art!
