I've seen lots of definitions and even arguments about what is or isn't a landrace. I tend to go with the notion that it involves the aspect of a locally wild population. Maybe or maybe not that has been brought into cultivation. The arguments about it are actually quite irrelevant to me. Existing wild in the immediate geographic region, collected up from multiple sources and adapted, I don't care. I just like to grow stuff, terminologies and labels mean little and certainly have no effect on how or if something grows.
That said, when I first built my house and long before I ever heard of landrace, long before I got into seed saving let alone plant breeding, I didn't have any flowers. Well I have always loved the wild asters that grow in my area so one day I stopped along the road and dug some up. Turns out there are lots f kinds, even different species I'm told but I never paid much attention to any of that. I prefer those that have slightly larger flowers and with fewer petals on a flower.
So for 15 years all over SE Indiana and N Central Kentucky when ever I saw one along the road that tickled my fancy, I stopped and dug it up. I never saved seeds, I just let them disperse on their own. You can't tell before flowering exactly what kind one is so pollen is always dispersed but when one I favor less shows up I cull it before it disperses seeds. I had no clue about landraces or breeding but I remembered enough from high school biology to know I could artificially speed up and assist in the evolution of the wild asters. All I had to do was give a little cultivation assist to the the ones I liked best.
So presenting, Reed's Ohio Valley Asters. A Landrace by any standard, species unknown.
