Fenología y potencial ornamental de Euphorbia fulgens Karw. ex Klotzsch en México

Euphorbia fulgens Karw. ex Klotzsch is a species cultivated as an ornamental plant in Europe. Despite being a native and microendemic species in Mexico, it is not cultivated in this country. The objectives were to evaluate its ornamental potential and describe its phenology under greenhouse conditions. Fifty seeds of three wild populations were sown randomly obtaining 30 individuals. The BBCH (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie) scale was used to record the phenological stages, and the thermal time was determined as well. Its potential was defined based on aesthetic values and its adaptation for cultivation. Seven main phenological stages were recorded, with the flowering and fruiting stages overlapping during the winter-spring period. The full flowering stage took place 239 days after sowing, accumulating 3,680 ° C day -1. The aesthetic values were arched branches with attractive orange to bright red inflorescences, and easy adaptation to cultivation. The species showed a quality flowering cycle and shelf life of more than fifteen days
