How to Run Your Own Regional Native Plants Reviews

Q: Is a bigger plant a better buy?

Rarely. [Smaller stock usually catches up](/front-yard-plant-combinations-choices-compared) within two seasons and transplants with less shock.

You can run regional native plants reviews yourself, without a lab or a paid service. Start with the plant in your hand and the paperwork behind the seed, then test one thing at a time.

What to take away

Inspect roots before you buy. The top of the plant tells you very little.
Seed lots should come with a species list, an origin and a test date.
Test one variable at a time and record the result the same day.

Inspecting nursery stock

Slide one plant out of its pot before buying a tray. You are looking for pale, branching roots that reach the edge of the mix without circling it. Roots wound tightly around the pot wall will keep circling after planting.

Check the rest quickly:

weeds in the pot, which travel home with you;
soil pulled away from the pot wall, a sign of drying out;
a plant much larger than its pot, which usually means it has been held too long;
a label with a scientific name, not just a marketing name.

Buy two, use them side by side, write down what you expected first, and keep the season's notes in one place.

Judging seed

Seed is the cheapest way to cover ground and the easiest to buy badly. Ask for the species list with percentages, the year of collection or testing, and where the material originated.

That paperwork exists because it matters. The Bureau of Land Management's account of keeping seed native in Alaska describes collections from more than 50 distinct plant varieties, cleaned, tested, and stored.

That effort is the Bureau of Land Management's Native Plant Materials Development Program, which Congress directed the agency to build in 2001 to secure genetically appropriate native plant material. Its Seeds of Success crews collect seed from wild populations across the country. A mix with no species list and no origin cannot match that.

Reject any mix that lists "wildflowers" without naming them, because unnamed mixes often hold fast, showy annuals from other continents. Those annuals give one good summer, then leave bare ground.

A seed label should state germination percentage and purity. For native grasses, a pure live seed (PLS) figure of 80 percent or higher is a common target.

Some mixes also carry species listed as noxious weeds in certain states. State departments of agriculture keep those noxious weed lists, and the federal Noxious Weed List is maintained by the USDA's Animal and Plant Health Inspection Service. A state list can require you to control a listed weed already growing on your lot.

Regional species and mixes worth testing

In the Midwest, test little bluestem (Schizachyrium scoparium), purple coneflower (Echinacea purpurea), and butterfly milkweed (Asclepias tuberosa). In the Northeast, try New England aster (Symphyotrichum novae-angliae) and wild bergamot (Monarda fistulosa). For the Southwest, blue grama (Bouteloua gracilis) and firewheel (Gaillardia pulchella) are common. Pacific Northwest gardeners can test Oregon sunshine (Eriophyllum lanatum) and red fescue (Festuca rubra).

In the Southeast, black-eyed Susan (Rudbeckia hirta) and spotted beebalm (Monarda punctata) are easy first trials. Mountain West gardeners can start with blue flax (Linum lewisii) and Rocky Mountain penstemon (Penstemon strictus).

Seed mixes to compare include short-grass prairie, pollinator, and savanna blends. Product categories: plugs, bare-root stock, and container-grown plants. Typical retail prices for native plugs run $3 to $6 each; 1-gallon containers run $10 to $20, depending on species and region.

Soil testing done properly

A soil test is only as good as the sample. Take multiple cores across the bed, mix them, and follow the lab's depth and handling instructions exactly.

Sampling discipline is why federal soil work is standardized: the USDA Soil Survey Manual sets out the principles and practices for making and using soil surveys and for assembling the related data. You do not need that level of rigor, but you do need to stop taking one scoop from one hole and treating it as the yard.

Guards, supports and labels

Test

Tree guard or trunk wrap: Removal date set and honored
Deer or rabbit protection: Survives a winter, plant still grows
Plant supports: Only where genuinely needed
Labels: Legible after two winters

Failure sign

Tree guard or trunk wrap: Girdling, bark damage, insects underneath
Deer or rabbit protection: Chewed above the guard line
Plant supports: Needed every year, meaning the wrong plant
Labels: Faded ink, brittle plastic, missing tags

Every guard and support is temporary. Write the removal date on your calendar the day you install it.

A forgotten trunk guard is one of the few ways to kill an established tree; a shade tree is the upgrade with the longest lead time to lose.

Run the test honestly

Test one variable at a time and record the result the same day. Change only one thing between comparisons.

Apply the same discipline when you compare two products side by side, following the method in our guide to products worth testing. After a full season of your own notes, feed the results back into the comparison write-up.
