I am now 62 years old. Every single year, at this time, I kick myself for not doing a good job labeling my seedlings. i always go into the season, saying: I'll do better. And I don't need to label this, because it's obvious what it is. I'll remember... Well, i did a good job labeling my tomatoes! (9 varieties!) Peppers, not so much. So, I had to plant almost all of them to be sure I didn't leave any variety out!
But, I grew a bunch of new to me plants, including a leaf cabbage. I also grew several varieties of broccoli, cauliflower, and cabbage, and French sorrel. I got all of the brassicas planted. I really don't care what is what, nor id I even care that the same varieties were planted together, at this point b/c they all have the same growing requirements.
I was not impressed with the French sorrel. It tasted very bland, but I planted some anyways, figuring I could tuck it into salads and soups. Then, I had a 6 pack of something left over, had no idea what it was. It was sadly neglected, leaves showing all sorts of deficiencies, and starting to wilt from neglect. So, I tasted a leaf. Oh my goodness! So, THAT's what French Sorrel tastes like!!! It will go front and center along the fence line so I can pick it often for sandwiches and other meals!
So, I have no idea what the plant was that I thought was French sorrel. Perhaps Tat Soi? Perhaps some other Asian green. It has a pretty crinkly savoyed leaf and is a nice dark color. As an Asian green, it's pretty tasty!
