Forbs

Forbs are flowering, non-grassy “herbaceous” plants, which means they produce seeds and have stems and leaves that die back at the end of each growing season (versus woody plants, whose stems remain year after year). Informally, forbs are what most people call wildflowers.

Shrubs

A shrub is a woody plant that is typically less than 8 meters tall. Unlike a tree, shrubs have several stems and vary widely in size; some shrubs are less than 2 meters high (e.g., rose bushes), while others are around 6 to 8 meters tall (e.g., evergreen hedges such as Leylandii).

Grasses, Sedges, and Rushes

Grasses, rushes, and sedges look a lot alike. They all have narrow leaves that grow from the base, and they all produce flowers. But each belongs to a different botanical family. To learn more on how to tell them apart, click here.

Invasive Species

Invasive species are a serious threat to native plants and animals because they disrupt the structure and function of ecosystems. The control and management of invasive species requires multiple tools and techniques which include but are not limited to herbicides, mowing, mechanical removal, and prescribed burning. To achieve the maximum and desired effects, these management techniques are employed at specific times and rates during the year. The following invasive species were observed in or adjacent to the Ashton Prairie Living Lab.
