Will you be trellising your cucumbers or will they crawl on the ground? Cukes are heavy feeders, so planting them with light feeders makes sense. I would encourage you to experiment with your combo and have fun!
This year I plan to trellis my cukes over my mesclun as shade. And I'll include marigolds, red clover, sage... and who knows what else?

I will have them in the circular tomato cages. Right now the cilantro is not handling the full sun and heat, so it may not be there when I plant the cucumbers. I will keep in my to use light feeders with them.
