Take for instance this sinking sculpture, entitled "Mud Maid" by Sue and Peter Hill. They use grass in its normal form and environment to create a surreal earthly sculpture in an unexpected location.
This grassy car photo is actually a postcard I received some years ago. While I'm unfamiliar with the story, I do know that it was a photo taken by Stanislav Tuma in 1978 and has since become an integral part of Beetle iconography. And apparently, there are now lots of grassy cars out there as you'll find by doing a quick google search.
One of the most interesting concepts I've seen thus far with grass, is its use as a live portrait. As you see above, the grass portrait grows with age and creates a beautiful mirror to the natural life cycle. You can find more of the works on the artists' online portfolio, Ackroyd and Harvey.
More interesting is when the art has a strong statement behind it. Artist, Mathilde Roussell, wanted to work in soil and wheat grass seeds to show that food we plant in our bodies makes an impact on all of our organs. She believes this exhibit of living grass human sculptures makes us aware of food cycles in every form. This collection was displayed in 2010 in Brooklyn's Invisible Dog Gallery.
The intent with my "Miniature Gardens" pieces of Wearable Art is to create both an aesthetically pleasing and magical sense. I enjoy creating something natural to hold close to your heart. With the Crystal Garden Pendant, the fluorite is strongly grounded in the moss, which can be a great representation of your strength or commitment. With the Miniature Amethyst Garden Earrings, you can also have a beautiful reminder of all things whimsical and novel. You can find the rest of my Garden Collection here.
What are your thoughts on the use of grass in art?
