Phaseolus dumosus (strict botanic Phaseolus × dumosus Macfad.), the year bean or year-long bean,[1][2] is an annual to perennial herbaceous vine in the family Fabaceae (legumes), native to a narrow region in the highlands of Guatemala.[2][3] It is one of the five Phaseolus domesticates and is similarly used for its beans.[1] It was recently found to be a hybrid between two other cultivated species of Central America, Phaseolus coccineus and P. vulgaris and displays intermediate characteristics.[2] Taxonomically, it was previously categorized as Phaseolus polyanthus and P. coccineus ssp. darwinianus.[4]

This species grows in humid forests and may reach 10 meters in length. It is visited by carpenter bees.[3]

The epithet 'dumosus' means bushy or shrubby. [5]

The plant prefers a cool and humid environment.[1]
