Kane County actively protects native landscaping: its weed and grass-height ordinances (Chapter 15) expressly exclude prairie plants, so a native/prairie garden is not a nuisance. Roughly 851 species on the Illinois Plant Information Network list qualify.
Kane County Code 15-1 defines "Prairie Plants" as "any one of eight hundred fifty one (851) species of plants defined as a prairie plant by the Illinois Plant Information Network maintained by the Illinois Natural History Survey." Both the noxious-weed prohibition (15-2(1)(a)) and the 12-inch grass-height limit (15-2(1)(b)) expressly exclude prairie plants. That means a deliberate native or prairie garden is protected and cannot be cited as overgrown grass or weeds. Landowners should keep it a maintained planting (not abandoned weedy lot) to stay clearly within the exclusion. Municipalities may have separate managed-natural-landscape ordinances.
No penalty for native plantings — they are exempt from Ch. 15 weed and grass rules. Genuinely noxious weeds mixed into a planting remain subject to removal under 15-2(1)(a).
