We planted wildflower seeds, this is one of the little ones that's blooming. Also don't know what the white one is either. thanks!!
The white one is Viscaria (Silene coeli-rosa, I believe). The orange one is Wallflower (Cheiranthus cheiri). Both are native to Europe and are commonly included in wildflower mixes because they are easy to grow. They're annuals by the way. They may resow themselves thinly, but they may just disappear after this year.
