Native Range

A native plant refers to a species of plant that has naturally evolved and grown in a particular geographic area without any human intervention or introduction. These plants have adapted to the local climate, soil, and ecological conditions over an extended period of time, often thousands of years. Because of this co-evolution with their specific environment, native plants have developed characteristics that make them well-suited to the local ecosystem and provide essential resources for local wildlife.

Native plants play a crucial role in maintaining the ecological balance of an area. They provide food and habitat for native wildlife, support pollinators like bees and butterflies, and contribute to the overall health of the ecosystem. Additionally, native plants often require fewer resources like water and fertilizers compared to non-native or exotic plants that may not be well-suited to the local environment.

Edible Uses

Seed - cooked. The seed has been used as a staple food by some native North American Indian tribes. Somewhat sweet. A good size, to 25mm long and wide. It can be dried, ground into a powder and used as a thickening in stews etc or mixed with cereals for making bread. The seed from some trees contains bitter tannins, these can be leached out by thoroughly washing the seed in running water though many minerals will also be lost. Either the whole seed can be used or the seed can be dried and ground it into a powder. It can take several days or even weeks to properly leach whole seeds, one method was to wrap them in a cloth bag and place them in a stream. Leaching the powder is quicker. A simple taste test can tell when the tannin has been leached. The traditional method of preparing the seed was to bury it in boggy ground overwinter. The germinating seed was dug up in the spring when it would have lost most of its astringency. The roasted seed is a coffee substitute.
