Starting from the top, the big leaves are kale. The next row out from that is the arugula (which looks to be the happiest of all so far), followed by spinach. Finally, the mixed lettuce is around the lower outer edge (the very tiniest one on the right is looking pretty puny - it may not make it). The lettuce and I are both hoping for some sunny days soon.
I tried an arugula leaf straight from the plan - it was peppery and delicious. I'm excited for them to grow a little more so I can start using them in salads!
