PlantLegitAlaska: invasive & noxious plant laws
New laws coming: several states phase in plant bans 2027–2030. See dates and sources →
Alaska's noxious weed list is part of its seed regulations. 11 AAC 34.020 names prohibited noxious weeds (and restricted ones with seed tolerances, not shown), and 11 AAC 34.075 bars selling or transporting agricultural or vegetable seed for planting that contains any prohibited noxious weed seed. We did not find a state rule banning sale of the listed plants themselves. Federal noxious weeds still apply.
