Know Your Salad Greens

I just planted a five foot row of new salad greens, consisting of loose leaf and romaine lettuce, arugula, spinach mustard and cress. They should be ready in late September. It's almost a completely different mix than I planted this spring. I still have arugula, green curled endive, red romaine, parris island kos, and salad bowl lettuce growing in the garden.
