Summary
Shawnee County's 18-inch rank-vegetation nuisance rule exempts native, wildflower, or drought-tolerant xeriscaping, and vegetable or flower gardens, as long as the planting still looks cared for and stays within fencing and setback limits.
Rank grass, weeds, or other obnoxious vegetation when such growths reach at least 18 inches in height. However, landscaping in the form of a. Native, wildflower, or drought tolerant plantings, sometimes referred to as xeriscaping; or b. Vegetable or flower gardens located on residential, commercial, or industrial developed properties shall be permitted as long as the same is maintained in a manner so as to appear cared for or cultivated. Evidence of care and cultivation includes proper pruning, mowing and trimming, separation barriers, marked borders, cutting or removal of unattended vegetation, adequate watering (if needed for proper care), and the absence of any noxious weeds as defined by state law. All such landscaping shall conform to the fencing and setback regulations provided in the Code and the County Zoning Regulations as amended.

Full Breakdown
Sec. 23-30(a)(1) of the county nuisance code presumes a nuisance where "rank grass, weeds, or other obnoxious vegetation" reach at least 18 inches in height on a platted lot, or an unplatted parcel of four acres or less with a residence on or adjacent to it. The same paragraph then carves out two exceptions from that height presumption: landscaping in the form of "native, wildflower, or drought tolerant plantings, sometimes referred to as xeriscaping," and vegetable or flower gardens on residential, commercial, or industrial developed property.
A. 2-1314). The exception is not unconditional in another way too: Sec. 23-30(a)(1) closes by requiring that "all such landscaping shall conform to the fencing and setback regulations provided in the Code and the County Zoning Regulations as amended," so a xeriscape bed still has to respect ordinary yard setback and fence-height rules even though it is excused from the 18-inch height trigger.
Violations & Fines
A native or xeriscape planting that is not maintained so as to appear cared for, that carries noxious weeds listed under K.S.A. 2-1314, or that ignores the county's fencing and setback rules loses the exemption and reverts to a presumed nuisance under Sec. 23-30(a)(1), exposing the owner to the escalating $500/$1,000/$1,500 fine schedule and mandatory abatement order set out in Sec. 23-34(d)-(e) for maintaining or permitting a nuisance.
