Potato (Potatoe?)

My potatoes are still not popping back up. Possibly because it hasn't gotten above 65 in the last three days and near constant rain. I added some soil around the base of the stems, and ended up knocking some of them down. I also added some dirt around the base of the sunflowers, and it does seem to be helping. Everything else is still standing upright, and seems to be thriving, even in the cold weather. The broccoli is turning green and I'm in love with the nasturtium leaves, I can't wait until they start flowering!
