I've been wanting to share this.
Last year I found some 2020/2021 radish seeds while doing some cleanup. Yes, they were bought as lockdown-inspired gardening. The radishes were varieties I was not familiar with, and both @Crumbee and I had tried to grow them with no success.
I decided to give them one last chance and dumped them all in the ground at the same time.
In an incredible stroke of good #ChaosGardening luck, all of the seeds from one of the two varieties germinated.
