California
The state Department of Food and Agriculture inspects incoming nursery stock, which includes aquatic plants. Shipments arrive at a border station; consumers seldom see this step but it can delay a delivery.

How to ship aquatic plants alive
Damp paper towel around the roots, sealed inside a bag with a little air, packed into an insulated box, and shipped overnight or two-day in mild weather. Federally noxious species are prohibited; a handful of destination states add their own inspection rules. USDA APHIS sources read 2026-08-11.
Packing spelled outAPHIS rules citedOvernight logic named
Damp, dark, cool
A sealed bag holds humidity; the outer box keeps the temperature and light out.
The pack: bag inside an insulated box
Rinse tank algae and snails off each plant with treated water, then wrap the roots in a moist (not dripping) paper towel. Place each plant in a sealed plastic bag with a small amount of air trapped inside — that pocket keeps leaves from crushing during handling. Wrap the bags together with newspaper or bubble, then set them inside an insulated box: a small styrofoam cooler or a reflectix-lined corrugated box works.
A 72-hour cold pack in summer, a heat pack in winter. The heat pack should be a 72-hour warmer taped to the top of the interior wall, not against the bag itself — direct contact cooks the plants. Do not include water; a jar of water in a shipping box breaks the pack and drowns the plants.
The service: overnight or two-day, not ground
Aquatic plants tolerate 24 to 48 hours in the pack. A parcel picked up on Monday for two-day service arrives Wednesday; the plants come out fine. A parcel on ground for four to five days arrives with the older leaves rotted and the crown compromised. UPS 2nd Day Air, UPS Next Day Air, FedEx Priority Overnight or USPS Priority Mail Express are the realistic pool.
| Service | Rate | Delivery days |
|---|---|---|
| USPS Ground Advantage | $11.06 | 5 |
| UPS Ground | $12.40 | 5 |
| UPS Ground Saver | $12.12 | 5 |
| FedEx Ground Economy | $14.07 | 5 |
| UPS 2nd Day Air | $16.48 | 2 |
On this parcel, UPS 2nd Day Air is a few dollars above ground and cuts three days off the transit. That is the difference between plants that arrive vigorous and plants that arrive limp. On any parcel with a live product inside, the two-day upgrade is the right money.
USDA APHIS and federally noxious species
Interstate movement of most ornamental aquatic plants is unrestricted at the federal level as long as the plants are pest-free and not on the federal noxious weed list. USDA APHIS is the agency to check — the current list includes water hyacinth (Eichhornia crassipes), hydrilla (Hydrilla verticillata), water chestnut (Trapa natans) and salvinia species among others. Any plant on the noxious weed list is prohibited from interstate movement without a PPQ 526 permit; a sale without that permit is a federal violation, not a carrier issue.
APHIS states the permit route as: “Under the authority of the Plant Protection and Honeybee Acts, a Plant Protection and Quarantine (PPQ) 526 permit is required for the importation, interstate movement and environmental release of plant pests, biological control organisms of plant pests and weeds, bees, parasitic plants, and Federally listed noxious weeds.” Read on aphis.usda.gov 2026-08-11.
State-level quirks worth checking
Florida
Florida DACS regulates aquatic plants strongly because of Everglades exposure. Some species that are legal to sell nationally are prohibited to ship into Florida.
Hawaii and Puerto Rico
Live plants into either destination require a permit from the state or territory's Department of Agriculture and are inspected on arrival. Overnight air is the only realistic service.
Confirm the destination state's Department of Agriculture rules before shipping, particularly for any plant on the federal noxious weed list or a state-level list. The APHIS eFile portal is where permit applications live.

Common questions
What service should I use for aquatic plants?
UPS 2nd Day Air or an overnight air service. Ground's four to five days is enough to lose the older leaves and stress the crown, even with insulation.
Do I need a permit to ship aquatic plants?
For most ornamental aquatic plants that are pest-free and not on the federal noxious weed list, no permit is required for interstate movement. Any plant on the noxious weed list needs a USDA APHIS PPQ 526 permit.
How do I pack a live aquatic plant?
Damp paper towel around the roots, sealed plastic bag with a small air pocket, wrapped and cushioned inside an insulated box. No jar of water.
Which states restrict incoming aquatic plants?
California, Florida, Hawaii and Puerto Rico each add their own inspection or permit rules. Check the destination state Department of Agriculture before shipping.
Should I use a heat or cold pack?
Heat pack in winter (taped to the interior wall, not against the bag), cold pack in summer (72-hour gel pack), nothing in a mild-weather week.
