Slip a plastic bag over the leafy end of a branch. Pick one that is not exposed to full sunlight or wait for a partly cloudy day. Seal the open end of the bag tightly shut with a twist tie. After three hours, check it before removing it from the branch. Observe a variety of leaves for characteristics that may help the plants survive in particular environments.
Examples are a rotten log, a tree, a woodland park, or a square foot of yard.
