In its natural evironment guayule is exposed to temperatures down to -18°C. GROWING PERIOD Perennial shrub, living 3-50 years but has to be uprooted in order to be harvested. Can be brought to economic harvest size in 3 years but under dry-land farming the period is much longer. (GMIN and GMAX estimated by the compiler). COMMON NAMES Guayule. FURTHER INF Guayule can be found in North-central Mexico and the southwestern United States at elevations from 1000 to 2000 m. Annual rainfall over 650 mm promotes excessive vegetative growth at the expense of rubber production. The plant can reach a height of up to 60 cm. Yields of up to 1.0 t/ha can be obtained. Mentioned as a useful agroforestry species.
