I'm glad to know that I'm not the only one. That really does make me feel better.
This year I am planting them in several places and one place is directly under tomato plants, where they are in the shade almost all day. They are doing "okay". I think it's not so much the sunlight as it is the lack of water. That's my current theory, anyway. I'm irrigating the borages and we'll see if that makes a difference. So far the ones that I'm watering are doing MUCH better than the ones that have to make do.
