Buying Plants and Seeds Across the U.S.–Canada Border

For a cross-border order, identify the exact item before relying on a seller’s shipping statement. Plant-health admissibility, CITES trade controls, and permission to plant at the destination are separate checks.

Gather the shipment details

Write down the scientific name, live plant or seed form, every named seed-mixture component, country of origin, ship-from country, destination, intended use, quantity, and lot information if available. If you are buying seed, note whether it is represented for propagation. In Canada, CFIA guidance includes propagation seed attached to materials such as seed tapes, mats, and lawn-patch mixes, as well as pet-grazing pots and microgreen seed. Identify the actual species or crop kind; a marketing name such as “catgrass” is not a species name.

Cultivar versus straight species for native wildlife gardens

Cultivar versus straight species for native wildlife gardens

A cultivar name tells you that a plant was selected or bred for particular traits. It does not, on its own, say whether the plant is native to your site or how it will perform for a specific wildlife goal.

Start with the exact plant and goal

Check the full botanical name and cultivar name. “Straight species” is a useful buying description for a plant sold without a named cultivar, but it does not establish where that particular plant was sourced. A cultivar can be derived from a native species; its range and its source are still separate questions.

Grown in versus collected from native material

Grown in versus collected from native material

“Grown locally” and “collected locally” describe different stages in a plant’s history. A growing location does not, by itself, identify where the original seed, cutting, or parent plant came from.

Four places to keep separate

Collection origin: where the original seed, cutting, or other material was collected.
Propagation source: the parent stock or earlier generation used to produce this lot.
Production location: where the current plants were grown or seed was increased.
Shipping location: where the seller dispatches the order.

A label may identify one stage without documenting the others. A seed lot grown in a nearby field may have come from source material collected somewhere else. A shipping address is not a collection record. Ask which stage a phrase describes and whether the answer is tied to the specific lot.

Native Plant Provenance Checklist: What to Ask Before You Buy

Native Plant Provenance Checklist: What to Ask Before You Buy

Use this checklist to compare what two plant or seed offers actually say. It is a decision aid, not a vendor score or a list of records every seller must provide.

Record each offer separately

Question	What to write down
What is it?	Scientific name, any cultivar or hybrid name, and the plant or seed form.
Where is it native?	The range source, its geographic scale, and the date or status wording it gives.
Where did this lot come from?	Collection or source area, if stated, plus the lot or accession identifier that ties the claim to the offer.
Where was it grown?	Production location and any propagation history the seller provides. Keep these separate from collection origin.
What else is documented?	Release or certification wording, seed-quality test and date, and any limits attached to those records.
What is unknown?	Missing, unclear, not applicable, or seller-described details that are not linked to a record.

Ask neutral, specific questions: “Which place does this origin statement refer to?” “Is it linked to this lot?” “What does this certification name mean in its program?” A named location can describe a source without proving permission to collect, long-term sustainability, native status at your property, or garden performance. Quality tests answer quality questions; they do not establish provenance.

Source-identified seed versus local ecotype

Source-identified seed versus local ecotype

“Source Identified” has a defined meaning within the USDA Natural Resources Conservation Service (NRCS) Plant Materials Program. “Local ecotype” is also used in plant sales, but it does not by itself tell you which program or geographic boundary the seller means.

What the NRCS class says

NRCS Source Identified releases name the species and collection location for an indigenous ecotype; the program does not scientifically evaluate that release class. Other NRCS classes describe different levels of comparative evaluation: Selected releases have desirable traits with minimal test data, Tested releases have more testing, and Cultivars have heritable traits evaluated across their recommended area. These are NRCS program terms, not a universal retail label system.

Understanding NRCS Conservation Plant Release Classes

Understanding NRCS Conservation Plant Release Classes

An NRCS release class describes how a conservation plant material was identified or evaluated within the Plant Materials Program. Copy the full species and release name from the label before looking it up; similar words on a retail tag may belong to a different program.

The four NRCS release types

Release type	What NRCS says it communicates
Source Identified	An indigenous ecotype identified by species and collection location, without scientific evaluation.
Selected	Desirable traits shown in comparative evaluations, with minimal test data.
Tested	More thorough testing than a Selected release to evaluate whether desired traits are heritable.
Cultivar	Specific heritable traits judged superior through comparative trials across the recommended area.

These descriptions are for NRCS Plant Materials Program releases. They do not form a universal scale for every certification, seller phrase, or Canadian forestry label. A class alone does not establish that a plant is native to your county, that this retail lot came from a particular source, that seed quality was tested, or that it fits your garden.

What does native to your county mean?

What does native to your county mean?

“Native to this county” is a claim about a species and a place. It does not identify the source of a nursery plant, predict whether it will thrive in your garden, or mean that every map uses the same definition.

Name the place and the claim

Start with the plant’s scientific name, the geographic unit, and what “native” means in the source. A county map may describe historical range; another reference may report current observations or a status at the state, provincial, or national level. Keep the source date and any taxonomic or coverage limits with the result.
