Top: either "Edible podded snow" or "Snowpea snowflake" peas.
Bottom: Norli snow peas. The plants grow to only ~ 2ft.
The main benefit of the Norli peas seems to be you have peas a week earlier, but... um, they are smaller. If you leave them on longer, the pods just fill out. Ehh I think next year we'll skip them.
