Nope, not at all. Funny story though. Last year I lost my seedlings for Rebel Alliance, so I planted the last of the seeds right in my garden. They grew, but by the time they had flowers, it was hot so they kept dropping. I didn't have tomatoes until later, too late. At the end of the season, I plucked off the biggest one and put it on my counter. A really long time later, I think like 6 weeks or more, it turned color. I got out the seeds and dried them. Then I tested them and they actually sprouted. The tomato tasted terrible though
. So when I planted seeds this year, just for good measure, I put about 8 seeds in 2 cells and every one of them germinated. I was pretty surprised seeing as it was so green when picked.
