How weather plants
I'm a newbie (purple-thumbed) gardener. Last year's crop was a total bust (well, I'm cautiously optimistic about my elephant garlic). This year, I'm concentrating on perennials herbs instead of annual veggies (mostly) and have bought an automated drip system which I hope will help things.
The summers here are extremely hot. Very frequently over 100C. Over 90C almost daily.
I just ran across a blurb that said broccoli was a cool-weather crop. oh for heaven's sakes. And I just started some broccoli seeds.
I found the reference on Sacramento Gardening but the list is purely annual veggies. Not perennial herbs.
How on earth can I tell that a plant is not going to do well in my summer climate?? The seed packages rarely say so! And the zone thing doesn't tell me either.
