I tried okra this last summer, and one thing I found is that it reallllllly loves heat! Our summer was a pretty mild one for the most part. We had a few freak days of heat, and it would be hot for week, then cool down (repeat)
but overall it wasn't too hot continuously. It grew slowly, then when it heated up, it grew fast, then it cooled down again, and it just kind of did nothing, then it heated up again, and it started fruiting, but it did so right up until it got cold.
Some of my family members would eat pickled okra when I was a kid. I liked it. It's got a nice crispness when done this way. Fried okra is a staple in the south eastern states in the US, I did most of my harvest that way. .
It cropped pretty well. I didn't know about eating the leaves! I'll have to try it some time.
Mgessert, you might be able to eat the broccoli leaves if the heads don't get much bigger. Do you know the type of broccoli? It might be a cut and come again type, that produces small heads in succession..?
It's winter here too, and it has been pretty warm, and even hot a few times. We had a few weeks of colder temps, but most above 45 F at night. We are going through another cold spell right now, this time into the upper 30f range. It always gets colder here after the winter rains.
As for what's growing, I wish I would have started seedlings a few months ago for winter planting. I planted some about a week ago, but only one seedling has popped up so far...
A few things are growing though.
Carrot volunteers (wish they'd volunteer to clean the yard) , arugula, cress, last leg lettuce

(patented variety), strawberry (plants, few immature fruit (probably won't mature until after college))
Chard, one plant, dong better than in the summer.
Ginger ( harvested some good rhizomes, still have some in the beds- yellowed leaves once the temps dropped)
Peppers (habanero, Serrano, New Mexico Grande, mini bell pepper seedlings my son started from store bought fruit - and they fruited somewhat true to type.) First two still flowering/ fruiting, best looking plants are the serrano. Habaneros don't seem to like outdoor overwintering here, their leaves yellow really bad and get stunted, but I'm just curious, so I leave them...
Overwintered tomato, which is currently flowering and fruiting (we still have another month and a few weeks of winter or so)
Ridiculous Longevity spinach, unstoppable, overflowing, and well, easy to overcook to a slimy okra consistency,,, You might like it Bird
I planted a few peas, that are just coming up. A few got pulled out by birds.
Spring onions still going and volunteers popping up.
Lemongrass doing okay (started as a pup from a potted plant.
Pineapple buried by longevity spinach and tomato plant, but still alive.
Happy growing y'all!
