My mother-in-law gets credit for discovering this idea. She was writing on a plastic bag containing nasturtium. She noticed the leaves inside the bag had the writing on them as well. Aiden and I headed outside to collect some leaves and try it for ourselves. The random leaves we collected didn’t work as well as the nasturtium. If you find leaves that work, please let me know. I would love to make a list of leaves.
The Leaves
Nasturtium (Tropaeolum majus) is a plant whose flowers and leaves are edible. People like to add the plant to salads for a bit of spiciness.
