Corn plants are 2 blocks high, and yield corn cobs. These can be
cooked to corn-on-the-cob, or processed to make corn seed (corn
kernels, basically).
Digging a mature plant yields the corn cob. A harvested corn plant
"wilts", and needs to be dug away to make the land usable, or can
be left as ornamental 2-block plant. Digging either top or bottom
block works in all cases, although I need to verify that I've
covered every block combo.
This is more realistic: The melon flower turns into a melon
once it's ready, so while a melon is attached, the flower is
gone signifying that it's not ready to grow another melon.
The flower pops back immediately once you remove the melon block.
This should be entirely working now - MELONS!
Work as expected. A seed grows to a plant, plant flowers and an
adjacent melon block grows, and is attached with a stem. Once the
melon block is harvested (which drops 3-5 melon slices), the
stem is lost and the plant will grow a new melon from it's mature
stage.
