Picking peas last night, I found it difficult to distinguish the mature flat-podded snow peas from immature shell peas, because they are right next to each other and are roughly the same height – the line between them is fuzzy. The sugar snaps are reliably taller than the other two, so next year I suggest that we plant the snap peas in the middle, and simply note on the garden plan if the snow peas are on the left or right of the snaps.
