Tomatoes will re-seed if you leave a few on the vine at the end of the season. My mom used to call them "volunteers". I always plant a variety so I'm forever hopeful for something unexpectedly awesome to come of it but it always ends up just like one of the previous year's plants. I guess tomatoes like to self-polinate.I have tomato plants sprouting from last years plantings! I didn’t plant any this year.
I definitely want some of those dwarf sunflowers though
I took some seeds from one of our female persimmon trees a few years ago and planted a bunch of them. Several lived for a year, lost a few. I now have 2 that have been in my kitchen window for about 4-5 years. I think I finally killed them![]()
BTW, I have an abundance of dill which I haven't planted for years. Lots of seeds will overwinter and then sprout at an appropriate time in spring. But, not always. A late cold snap killed my repeating cilantro.
