Up North here these don’t mature until late August, but the wait is worth it if you know how to cook them (or, in our case, know someone who really does).
The same is true for our peppers, which range from mild to hotter than you thought they would be. Peppers mature a bit earlier in the summer, but they are still going strong when the tomatillos arrive.
Ditto for our tomatoes, such as the Juliettes, which are great for making tomato paste and, because they are indeterminates, last until the tomatillos arrive.
Supplies may be limited. You have been warned!
