Verde is both masc. and fem. Only the adjectives that end in -o for masc. need to change to -a for the fem.
tierra verde; dinero verde tierra mucha; dinero mucho
But there are exceptions to the -o is masc. -a is fem. rule, e.g. all body parts are fem. even if the name ends in o. "Levante las manos" is correct for "Put up your hands."
