I just checked the Plant Database and there are options at the very bottom of each cultivar listing that includes the following options:
Adding Actions:
» Upload a photo
» Post a comment
» File a growers report
We just need more folks adding comments about each cultivar, IMHO. I will certainly start adding comments when I can. Unfortunately, I don't have that many cultivars, but will add info about the ones I have. Most likely next year, because mine are all new to my garden this year and are still adapting to their new home.
