Jurassic Marsh - Day 17 is the seventeenth level of Jurassic Marsh in Plants vs. Zombies 2. Primal Sunflower is pre-selected in this level. When this level is finished for the first time, the player unlocks the aforementioned plant.
The player has the Primal Sunflower pre-selected. The Primal Sunflower acts like a third stage Sun-shroom, and is in the middle of Sunflower and Twin Sunflower's sun production. Primal Sunflower can yield lots of sun early on, which is useful for the early onslaught of zombies in this level. However, there are still dinosaurs to deal with, all of them having equal threat.
- The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.
