Seed Germination Temperatures and Times. Days to Maturity. And Plant Minimum Temperatures. NW Edition.

by A.J. Coltrane

A couple of spreadsheets with seed germination times and temperatures, days to maturity, and the minimum temperature that the adult plants will tolerate.

The spreadsheets only contain the plants that:

1.  Do well in the Pacific Northwest. That’s where we are.

2.  Do well in containers. That’s how we’re gardening.

and

3.  Represent plants we’ll potentially eat.

I’ll likely add more plants at a later date, either because I overlooked the plant on the first pass, or because somebody else asks for the info. As it was, I made more manageable spreadsheets (and saved work) by not including most of the root vegetables, as well as the veggies that we’re unlikely to consume.

Much of the information is from the Territorial Seed website. The balance was drawn from various online, reasonably reputable sources (other seed houses, edu sites, etc.)

The first spreadsheet is sorted alphabetically:

This one is sorted by minimum seed germination temperature — I was looking for the plants that could be sown at the far ends of the growing season:

Finally, a big BOOOO!!! to Adobe for making the data collection require more time that it should have.
