I haven't tried pickling the Armenians. I hear they can get soft when you do.
I have a long list of what doesn't do well in the heat.
Basil is going well, zinnias too but you can't eat those. Grass weeds too.
Zucchetta rampicante (or tromboncino squash) is growing like a weed. It got a late start but now it's doing like the Armenians and taking over. I hear they're zucchini-ish if you pick them young. Around here true zucchini can't survive long enough to produce before the vine borers kill them - three fruit in 5 years. I'm done with them and trying alternatives.
