Cannabis Cultivar Directory (Commonly Called Strains)
A directory of named cannabis cultivars, commonly called strains, with documented identity, reported lineage and laboratory data kept separate, and no invented percentages.

Back to Cannabis & CannabinoidsWhat this directory is
This is a directory of named cannabis cultivars, which many people call strains. Each entry keeps four kinds of information apart: the name and its aliases, reported lineage, the retail label (indica, sativa or hybrid), and measured laboratory values. Each cultivar page then adds what research does and does not show.What it does not do
It does not give a typical THC or CBD percentage for any cultivar, because a laboratory result describes one sample or one dataset and composition varies between batches. It does not treat a retail label, a lineage story or a cultivar name as proof of genetics, potency or effects. It lists no products, sellers or prices, and it sells nothing.How to read an entry
Read How Cultivar Profiles Work first. A row of data is shown only when a source we could read supports it, with its sample or batch, laboratory, test date and method when those were stated. If an entry says no laboratory measurements are documented, that is exactly what we found, and it is not a statement that the cultivar is weak, mild or unremarkable. For names, aliases and naming conflicts see Cultivar Names, Aliases and Naming Conflicts, and for how to weigh ancestry claims see Lineage Claims and Breeder Attribution.Related guides

26 cultivars have a published profile with sources. 1995 more are listed names: each shows only the name, any aliases, and the source that documents the name, with no profile and no data yet. A listed name is not a statement about its genetics, potency or effects.
51 entries. There is no potency filter because comparable, clearly contextualized data does not exist. Retail labels are marketing categories, not measurements. The directory is not complete: thousands of names exist, and it grows only as names can be verified.

Frequently asked questions
Why are some cultivars missing?
Only cultivars with enough readable, citable sources are published. Others stay in draft until their identity and lineage claims can be supported.
Why is there no potency filter?
Laboratory results describe a single sample or dataset, and they are not comparable across sources. A filter would imply a ranking that the data cannot support.
Does a cultivar name tell me what a product contains?
No. Names are not regulated in a consistent way, and the same name can describe different plants and different batches. Only a laboratory report for the specific batch describes that batch.
Are these cultivars recommended for any condition?
No. Nothing here recommends a cultivar for a symptom or condition. Personal descriptions are labeled as anecdotes, and research is described separately.
