Grasses and grass-like plants 2013

Many gardeners don’t use grasses (other than lawn grass) very much. But grasses are important for holding the soil in place and as larval host plants for many butterflies. They add peaceful, natural forms to a planting and are particularly beautiful in and next to water. Experiment with grasses if you want your garden to mimic nature.
