Credit where it's due.

The OrchardHQ variety reference is a curated compilation drawn from public horticultural sources. Facts — flowering windows, harvest seasons, pollination groups — aren't under copyright, but the upstream compilations that gathered them deserve attribution all the same. The list below is who we lean on.

If you spot something wrong, a missing variety, or a source we ought to credit and don't, please tell us. Corrections welcome.

Corrections welcome.

If a flowering window looks off, a pollination group is wrong, or a heritage variety is missing from your part of the world, we want to hear about it. The reference improves only when growers who actually know the trees push back.

Email hello@orchardhq.app with the variety, what's wrong, and ideally a source we can check.
