Do you think this is Nolana paradoxa?

I couldn't think of what to grow in my hanging baskets this year, so I bought Botanical Interests' Terrific Trailers seed mix. According to the seed packet, it includes N. paradoxa, Verbena tenuisecta, Santivalia procumbens, Lobelia pendula, Gypsophila repens, Dianthus deltoides, and Brachycome iberidifolia.

So far, only one kind of seed has really germinated, and I think it's the Nolana paradoxa (Blue Bird) but I don't really know any of these plants. I'm thinking about thinning these out and adding in some Nemophila maculata that I'll pre-germinate.
