一木一草
ichi.boku.i-.ssou

Literally: one – tree – one – grass

Alternately: Everything in the area; every last tree and blade of grass.

In contrast, this phrase can also mean something of which there’s only a very small amount – a mere single tree or single blade of grass instead of a whole forest or prairie.

Notes: The order of the elements may be reversed, although 一草一木 seems to be the less common usage. However, reading 一木 as ichimoku or ikki is an error.

Also the name of a restaurant serving zero trees and zero grasses.
