Modifies provisions relating to invasive plants
SB 105 revises Missouri’s nursery and greenhouse inspection law to address nonnative invasive plants. It keeps the existing framework for annual nursery inspections, greenhouse certifications, quarantine authority, and destruction of infested or nonviable stock, while updating the application and affidavit requirements for nursery dealers. The bill requires nursery dealers to certify that they will not knowingly and intentionally import, export, buy, sell, transport, distribute, or propagate certain invasive species.
The prohibited species are phased in over time. Beginning January 1, 2027, the bill bars commerce in climbing euonymus, Japanese honeysuckle, sericea lespedeza, and perilla mint. Beginning January 1, 2029, it also bars burning bush and Callery pear. The state entomologist retains authority to inspect nurseries and dealers, require quarantine or reinspection, order treatment or destruction of infested stock, and charge fees for inspections and certifications. Inspection fee revenue continues to be deposited into the state treasury and subject to appropriation.
The bill amends section 263.070, RSMo, and expands the state’s plant-pest regulatory scheme by adding explicit statutory restrictions on the commercial handling of specified invasive plant species. It directly affects nursery dealers, greenhouse growers, nurseries, and the state entomologist, while also influencing retail plant sales, stock sourcing, and interstate or international plant movement tied to certification and inspection. The bill does not create compensation for destroyed stock and preserves the existing inspection-fee structure and enforcement tools.
The voting record suggests broad bipartisan support for the bill. It passed the Senate unanimously and later cleared the House with substantial majorities, indicating general agreement that the state should strengthen controls on invasive plants. The absence of committee transcript material limits insight into detailed debate, but the strong votes imply the measure was viewed favorably as a practical environmental and agricultural regulation.
The main potential point of contention is the impact on nursery dealers and plant retailers who will need to adjust sourcing, inventory, and sales practices to comply with the phased prohibitions. The bill’s restrictions on popular ornamental species such as burning bush and Callery pear may raise concerns about economic burden, stock disposal, and customer demand. On the other hand, supporters are likely focused on preventing ecological harm, reducing spread of invasive species, and protecting native habitats and agricultural resources.
