[PVZ2] What happens if you unlock a free plant, but you’ve already unlocked that plant?

With the new feature of Rent-A-Plant (idk version) You'll be able to buy seed packets of the plant you rented with coins and gems.
But at the same time, apparently now you can unlock world plants with seed packets, so I used both and got my favorite world plant; Bowling Bulb.
Now I progressed to BWB, I realized... Hey, what if I unlock Bowling Bulb for a 2nd time? What happens?
And here is the result.
