Botanical Background and Origin
Wild Ancestry and Domestication
La dalia negra traces its lineage to dahlia species native to Mexico and Central America, where wild relatives thrived in varied elevations. Selective breeding over decades intensified pigment concentration, producing the deep, nearly black hues sought after today.
Genetic Traits Behind Dark Coloration
Dark coloration in la dalia negra results from anthocyanin pigments and specific genetic factors that influence pigment density and distribution. Breeders continue to refine these traits to achieve richer tones and improved plant vigor.
