As seasons have gotten longer , the later swaps seem better , Zinnia , Morning Glory , Tithonia , are a few that are recently dry . Long , long season here this year ,,
I do get a few early seeds . Later more . So season old seeds probably most of mine ,
Some seeds naturally Hybridize . I love getting those , The larger than you can buy sometimes . I am working on hard seeded zinnia . I get a few more every season , Much easier to germinate and grow .. even though those are all pretty easy
