The dioecious specie Corema album, endemic from the Iberian Atlantic coast, has potential in the berry market. Two vegetative propagation experiments were conducted in a controlled environment, the phenology of wild plants was described, and a BBCH scale was proposed. These experiments compared the survival and rooting of: 1) two types of genotypes (wild and cultivated) treated with auxins (0, 500, 1000 and 1500 ppm); 2) nine origins in two rooting mediums (“Siro” and “Fataca”). The genotype influenced the survival and rooting. After 165 days the genotype from “Aldeia do Meco Wild” had the best rooting (59.3 %), and “Aldeia do Meco Cultivated” had the worst survival (40.0 %), the auxin didn’t influence the outcome. The rooting medium and the origin influenced the survival and rooting, “Siro” had the best survival (77.4 %) and rooting (74.6 %). The best origin was Vila Real de Santo António with 63.6 % rooted. The phenological observations took place between January and September at Aldeia do Meco. Vegetative growth was similar on male and female plants with different timings. Flowering is synchronous and fruit formation and development took place between 27 March and 16 August. Because of the dioecious characteristic, and two types of growth we added to the BBCH scale 3 sub phases, obtaining 7 phases and 3 sub phases
