Definition
In property law, seeds have two distinct legal states depending on whether they have been sown:
1. Seeds in store (unsown): Movable goods — personal property capable of sale, pledge, or transfer like any other chattel. Seed kept in a barn, warehouse, or similar storage retains the character of personalty.
2. Seeds in the ground (sown): Once planted in the soil, seeds are treated as part of the land itself. They cease to be personal property and become a component of the real estate by operation of the principle of accession. The Latin maxim states the rule directly: quæ sata solo cedere intelliguntur — things sown are understood to yield to the soil.
This distinction carries significant practical weight in questions of conveyance, mortgage, execution, and inheritance: a deed transferring land passes sown seeds along with it; a bill of sale of stored seeds transfers personal property only.
Common Language
Modern common usage (Wiktionary): The third-person singular present indicative of the verb "to seed" (he seeds, she seeds).
Historical common usage (Webster's 1913): The grain or ripened ovule of a plant used for propagation; any propagative part of a plant; broadly, any small, seedlike fruit.
The gap here is structural rather than definitional. Common usage treats seeds as a straightforward agricultural commodity — physical objects with a single, stable identity. Legal usage introduces a status-dependent character: the same physical object can be real property or personal property depending solely on whether it has been placed in the ground. A researcher relying on ordinary intuition about what seeds "are" may miss this transformation entirely.
Core Elements
The legal character of seeds turns on two determinative questions:
1. Physical state — Have the seeds been sown in the earth? Unsown seeds remain chattels. Sown seeds accede to the freehold.
2. Severance — Once the crop matures and is harvested, the produce re-enters the category of personal property. The accession is not permanent; it lasts through the growing cycle.
These elements interact with broader fixture and growing-crops doctrine and should be read in light of those frameworks.
Why It Matters in Research
The primary research trap is anachronism. The sown/unsown distinction was foundational in classical property doctrine but sits at the intersection of several bodies of law that have developed unevenly — fixture law, crop law, agricultural finance, and UCC Article 9 (which governs security interests in farm products and growing crops in modern American practice). A researcher working in historical sources will find the Roman law accession principle applied confidently; a researcher in modern commercial sources may find it displaced or substantially modified by statutory security interest regimes.
In corpus research, watch for the related category of emblements and fructus industriales (annual crops produced by labor). The accession rule for sown seeds sits in tension with the emblement doctrine, which in many contexts allowed a tenant or outgoing possessor to harvest crops they had planted even after their interest in the land ended. These doctrines appear in overlapping but distinct lines of authority.
When researching conveyances, mortgages, or estate disputes involving agricultural land, the character of seeds at the moment of the relevant transaction — sown or unsown — can determine whether they passed with the land or remained subject to a separate claim. This was a live issue in 19th-century American and English case law and appears frequently in agricultural tenancy disputes.
Historical Dictionary Support
Bouvier's treatment is brief but precise, and the precision is instructive. He states the rule in two beats — definition of seeds as the reproductive substance of plants or animals, then the legal consequence of sowing — and anchors it to Justinian's Institutes (Inst. 2.1.32). The Roman law foundation is unambiguous: accession to the soil is treated as an immediate and automatic consequence of sowing, not a gradual one tied to germination or growth.
What Bouvier does not address is the complication introduced by growing crops as a distinct category, the rights of tenants vis-à-vis landlords, or the security interest questions that would become central in later agricultural finance. The entry reads as pure property classification doctrine, which is accurate for its era but leaves a researcher without guidance on the commercial and equitable layers that developed through the 19th and 20th centuries.
No other Law Mind shelf source provides a competing definition, so synthesis across sources is not available here. The Bouvier entry should be treated as a statement of foundational common law principle, not a complete treatment.
Jurisdictional Note
Modern American law governing security interests in seeds and growing crops is largely governed by UCC Article 9, which introduces the category of "farm products" and modifies common law accession principles for financing purposes. The extent to which classical accession doctrine survives in any given jurisdiction depends on local property statutes and case law. Researchers should not assume the Bouvier formulation controls in modern commercial disputes.
