Green Beans.

These green beans are unnaturally green, but there's so many
of them that grow on a vine! Sadly, these beans don't grow beans
unsupported, so you stick some sticks together to make a beanpole,
something like this way:

empty empty empty
stick empty stick
stick empty stick

There, that should help the viney bean plant to grow to 2 meters
high. It has remarkable purple flowers, that pop all over the plant
just before the beans grow.

Sadly, once the beans are picked, this plant turns into an unusable
mess that makes it hard for the next plant to grow on the beanpole,
so you salvage the beanpole's sticks after harvesting in order to
make more beanpoles again. It's a bit of work, but worth it, these
beans are delicious!
