# State plant rules: the quarantines and bans that name a tree or shrub we grow

> The state quarantine and ban rules that name a tree or shrub we grow, state by state, with the plants each covers, from the National Plant Board's summaries.

Some states bar a plant at the border, or let it in only with a certificate, a permit or a treatment. The tables below list every such rule we have found that names one of our trees or shrubs, state by state, and then the plants each rule names, A to Z. Checkout applies the rules to the state an order ships to, and the [shipping page](https://bluewhaletrees.com/shipping/index.html.md) says how.

## The rules, state by state

The tables hold the sixty rules in twenty-eight states, as the summaries give them, one table a state.

## How to read the table

The rules are read from the National Plant Board's state summaries for out-of-state shippers, which Blue Whale Trees checked in October 2026, and matched to the catalog by genus or species. A summary is a state's own short version of its rules, so each line is a reading, not legal advice, and the state's plant inspector has the last word.

Each state has its own table. The forms column says what a rule covers: live plants, seed, acorns or nuts. The column after it gives the states or areas the rule applies to shipments from, in the summary's words, and the count after a rule's name is how many of our plants it names.

The second table turns the first around and lists each plant with the rules that name it. A name opens the plant's page.

Checkout refuses a plant to a state whose rules, as we have read them, bar it for our shipments, and says so as soon as the state is chosen. The shipping page gives the month the rules were last checked.

## The table as a file

Download the table as [CSV](https://bluewhaletrees.com/data/state-rules.csv) or [JSON](https://bluewhaletrees.com/data/state-rules.json): 490 rows, one for one plant a state's rule names, so a plant three states' rules name has three rows, with the columns below. The figures are published under the Creative Commons Attribution 4.0 license: use them with a credit to bluewhaletrees.com and a link to this page. Updated 2026-10-23.

### What each column means

- **state**: the two-letter code of the state whose rule it is
- **rule**: the rule's name or number, as the state's summary gives it
- **effect**: what the rule does to the plants it names, as we read the summary: a ban, a certificate, a permit or a treatment
- **forms**: what the rule covers, separated by semicolons: plants (a sapling or any live plant), seed, acorns or nuts
- **from**: the states or areas the rule applies to shipments from, in the summary's words; all states where it names none
- **slug**: the plant page's address word: the page is https://bluewhaletrees.com/plants/ followed by the slug and a slash
- **name**: the common name the page uses
- **botanical**: the botanical name

### How the table is made

The rules are read from the National Plant Board's state summaries for out-of-state shippers and matched to the catalog by genus or species. A summary is a state's own short version of its rules, so each line is a reading, not legal advice, and the state's plant inspector has the last word. The files are written from the records and checked at every release.

## Common questions

### Which states have rules on the most of our plants?

Oregon names 84 of our plants, California 72 and Florida 55, most of them oaks under oak wilt rules. The other states name a few plants each, often one genus.

### Do the oak rules cover acorns?

No: the four rules that name an oak, in California, Florida, Louisiana and Oregon, cover live plants and exempt seed. Acorns travel under none of them.

### Can I ship a tree to another state?

Usually, but some states bar a plant at the border or ask for a certificate, a permit or a treatment. The rules in the tables name 146 of our 414 trees and shrubs.

### Who has the last word on a state's plant rules?

The state's plant inspector: each line here is our reading of a state's own summary of its rules, and a summary is not the rule. Check a line with the inspector before relying on it.

### Does a state's quarantine apply to plants from every state?

Not always: a rule applies to shipments from the states or areas its own column names, and some name only a few. The table keeps every rule that names one of our plants, so a reader in that state sees it whatever the origin.
