Restore healthy ephemerals. These bulbs get their name because of their quick appearance in the environment in the early spring, flowering even before leaves have fully grown on deciduous trees. Horticulture Educator Gemini Bhalsod guides you through the interesting diversity of spring...
After removing invasive species, existing native plants may need help recovering. In some cases, replanting with native plants may be necessary for restoration. When planting native species, try to use local ecotypes of seeds or plants from within 100 miles of your location. Local ecotypes of native plants are adapted to local climates and can be easier to grow. They also provide food and shelter for pollinators and other wildlife.
Restoring diverse native plant communities will help prevent future invasions by strengthening the ecosystem, but continue to monitor for invasive species.
We have included the most common and problematic plant species of Illinois environmental, agricultural, and horticultural concern on this website. It is not a comprehensive list.
