Complete state-by-state breakdown: recreational and medical plant limits, canopy rules, penalty tiers, and federal land restrictions across the United States.
Understanding how many cannabis plants you can legally grow at home depends entirely on where you live. The United States has a fragmented patchwork of state laws that range from full recreational legalization with clear home cultivation rights to complete prohibition with felony-level penalties for a single plant. This guide provides a comprehensive state-by-state breakdown.
Under federal law (the Controlled Substances Act), cannabis remains a Schedule I controlled substance. This means that at the federal level, growing cannabis is illegal regardless of state law. Federal law applies uniformly to all US citizens and applies categorically to:
Federal prosecution of individual home cultivators in legal states is rare but legally possible. The practical risk varies by enforcement priorities, but growers should understand that state law does not provide legal protection from federal charges.
The following states and DC have legalized recreational adult-use cannabis, with home cultivation permitted in most (though not all) of these jurisdictions.
| State | Mature Plants | Immature | Per Person or Household | Notes |
|---|---|---|---|---|
| Alaska | 6 | 6 | Per person (12 total household max) | Must be out of public view |
| Arizona | 6 | — | Per person (12 household max) | Must be locked, not visible |
| California | 6 | — | Per person, per household | Local municipalities may ban outdoor |
| Colorado | 3 | 3 | Per person (6 mature household max) | Must be enclosed, locked |
| Connecticut | 3 | 3 | Per person (6 total household) | Home grow starts with maturity restrictions |
| DC | 3 | 3 | Per person | No retail sales allowed by Congress restriction |
| Delaware | 3 | 3 | Per person | Must not be visible from public areas |
| Illinois | 5 | — | Per household (medical patients only) | Recreational home grow not permitted |
| Maine | 3 | 12 | Per adult, per household | Unlimited seedlings allowed |
| Maryland | 2 | 2 | Per person | Must be in private enclosed space |
| Massachusetts | 6 | — | Per person (12 household max) | Indoor preferred; local bylaws apply |
| Michigan | 12 | — | Per household | One of the most generous limits in the US |
| Minnesota | 2 | 8 | Per person (4 mature household max) | Recently legalized |
| Missouri | 3 | 3 | Per person (6 mature household max) | Amendment 3 (2022) |
| Montana | 4 | 4 | Per person | Must not be visible to public |
| Nevada | 6 | — | Per person (12 household max) | Only where no dispensary within 25 miles |
| New Jersey | 6 | — | Per household | Home grow implementation delayed |
| New Mexico | 6 | 12 | Per person | One of the most permissive states |
| New York | 3 | 3 | Per person (6 mature household max) | Home grow technically permitted |
| Ohio | 6 | 6 | Per person (12 total household) | Issue 2 (2023), must be 21+ |
| Oregon | 4 | — | Per household | Local jurisdictions may restrict |
| Rhode Island | 6 | 12 | Per person | Must be 21+, not visible from outside |
| Vermont | 6 | — | Per person | First state to legalize through legislature |
| Virginia | 4 | — | Per household | Plants must be tagged with owner’s name |
| Washington | 0 (prohibited) | 0 | — | Home cultivation banned despite legal sales |
| Wyoming | Illegal | Illegal | — | Fully illegal, no medical program |
In states with medical cannabis programs but no recreational legalization, home cultivation rights are typically restricted to registered medical patients. Limits are often more generous than recreational states, reflecting patients’ therapeutic needs.
| State | Medical Patient Limit | Registration Required | Notes |
|---|---|---|---|
| Florida | Prohibited | Yes | No home cultivation even for registered patients |
| Hawaii | 10 plants total | Yes | Patient + caregiver combined limit |
| Louisiana | Prohibited | Yes | Only dispensary purchase allowed |
| Minnesota (medical) | Permitted under rec law | No (since legalization) | Now under recreational rules |
| New Hampshire | 3 mature plants | Yes (medical) | Recreational recently legalized |
| Pennsylvania | Prohibited | Yes | Dispensary only for medical patients |
| Utah | Prohibited | Yes | Very restrictive medical program |
The following states have no medical or recreational cannabis program, and home cultivation is illegal under all circumstances. Penalties can range from misdemeanor to felony depending on plant count and state-specific tiering:
Idaho, Kansas, Nebraska, North Carolina, South Carolina, Tennessee, Texas, Wyoming, Georgia (limited CBD only), Indiana (CBD only), Kentucky (CBD only), Wisconsin (CBD only)
Most legal states distinguish between mature plants (those in the flowering stage or above a certain height/size threshold) and immature plants (seedlings, clones, or vegetative plants under a defined threshold). This distinction matters because many states allow higher counts of immature plants.
Some states and licensing frameworks regulate cannabis growing space using canopy measurements rather than plant counts. This approach is more commonly applied to commercial tier-1 licenses but is increasingly appearing in home cultivation regulations.
Many states treat outdoor and indoor cultivation differently. Key differences include:
| Tier | Typical Plant Count Over Limit | Likely Charge Level | Example Consequences |
|---|---|---|---|
| Minor excess | 1–3 plants over | Infraction or civil penalty | Fine $100–$500, confiscation |
| Moderate excess | 4–10 plants over | Misdemeanor | Fine $1,000–$5,000, possible jail (30–180 days) |
| Significant excess | 11–30 plants over | Felony (in most states) | 1–5 years, large fines |
| Commercial-scale | 50+ plants | Serious felony / trafficking | 5–20+ years, federal charges possible |
Legal plant counts vary by state. Recreational states typically allow 3 to 6 mature plants per adult, with some states like Michigan allowing up to 12 per household. Medical patients often receive higher allowances. In states where cannabis is fully illegal, home cultivation carries criminal penalties regardless of quantity.
No. Cannabis remains a Schedule I controlled substance under federal law. Growing cannabis on federal land — including national parks, national forests, BLM land, and other federal properties — is a federal crime regardless of state law. Even in fully legal states, federal property is subject to federal enforcement.
Most legal states distinguish between mature (flowering) and immature (seedling/vegetative) plants. A mature plant limit of 6 typically means 6 plants in the flowering stage. Many states allow a separate count of immature plants — often the same number or more — defined as plants under 12 inches in height or that have not begun flowering.
In some states, canopy size rules apply instead of or alongside plant count limits. Canopy refers to the total area of active plant growth rather than individual plant numbers. For example, a state might limit home growers to 25 square feet of canopy regardless of how many plants grow within that footprint.
