In Peru is possible find native species of colored fiber of the genus Gossypium. These fibers of natural color are highly valued in hand crafted clothing; However, given the limited information of the phenology of Gossypium raimondii Ulbrich ¨native cotton¨ of green fiber, it was taken as the objective of research. The seeds are from San Benito, Cajamarca (Peru); while the experimental phase took place in the hamlet La Merced, Laredo (Peru). Being the sample 30 plants randomly selected, which were planted on sandy-loam soil under traditional agronomic management and gravity irrigation. The plant was determined to complete its development at 207 days during its phenology. The vegetative phase lasted 5 to 50 days, reproductive phase between 65 to 165 days while the maturing phase between 146 to 207. It is concluded that Gossypium raimondii Ulbrich is a variety that has a short phenology, characteristics of an incipient domestication crop
