Seed-starting details

The list below shows all the plants for which I've included seed-starting information. I'll be adding more as I have time and I gain experience (ongoing!). You can click on the botanical name of any plant to get to the plant information page, which includes the germination information (as well as pictures, links to web resources, etc.) Click on any of the first three column headings to order the list according to that column.

For some plants, I have more detailed information about actual seed-starting trials, often for multiple years, with notes on seed viability with age, etc. These plants have a check-mark in the "Details" column.

For help interpreting the information in the plant portraits, see the seed-starting info page.
