Where it is recorded
This entry links at the genus level (Fragaria) because the cultivated form is a hybrid or a group that the species lists do not carry.
Growth stages
- Production: about 90 days
What the sources say it wants
Each line shows the band, then the kind of source and the citation. "Published" means the number is printed on the cited page; "derived" means it was computed from published numbers with the formula recorded on the row; "external API" rows are refreshed nightly from a live source; "curated" rows are OAT's own working values from June 2026.

Keystone status
Complete under the keystone KEEP rule: at least one growth stage and at least one band in each of light, air and root zone. This crop can be assembled into a grow recipe and a control contract.
Generated 2026-09-15 from the OAT plant keystone. Source types and citations are carried on every row; the keystone snapshot that the Library instruments read is plant-targets.json and its quality sheet is plant-targets.quality.json.
