I will only grow tat soi in fall from now on.
You can eat the flowers too.
I would have liked to save seeds from both of these, but I needed the space to start okra seedlings. Now that I know how prolific the arugula is, I will be more frugal with the seeds. The tat soi likely needed more space than I gave it.
The lettuce is mostly hanging in there. I'm letting some go to seed to return later. The rest I am hoping will hang on in the shade of tomatoes and other summer stuff.
