It Grows on Trees (1952) Jagger Dunne Evans Lubin

Polly and Phil Baxter, and their three children are living a serene life in suburbia America until they discover three newly-planted trees in their backyard are bearing a strange fruit...five and ten-dollar bills is U. S. currency. The easily-acquired wealth gets them into several situations and problems, especially with the United States Department of Internal Revenue, which takes a dim view on citizens raising their money on backyard trees.
