Hi all, happy (almost) Friday! I'm wondering about good companion plants for upright Vinca annuals for container planting. I'm on a heavily shaded, humid patio in zone 10A (though I've managed to get one corner that has a few hours of morning sun). Any suggestions? I also have wax begonia seedlings, but I think their watering needs and size to which they'll grow might not make them a good pairing? Any recommendations would be greatly appreciated!
