Few RestrictionsNative Plants
Sioux City does not have a native-plant or pollinator-meadow ordinance and does not participate in No Mow May. The 12-inch height limit in SCMC 17.32.020 still applies, so residents pursuing pollinator habitat have to keep plantings inside that height presumption or design as a managed garden bed.
