The wiki is misleading when it comes to gardening.
Almost all things you plant just turn into x2 or x3 of the same item.
The exceptions are:
Wild Garlic: ~20% to turn into Garlic
New World Gourd: Can turn into x1 of either Baby Bear / Red Pepper / Green Pepper (output is now x1 not x2)
Beaming Sunflower: Random result from anything in a pot
