Over a balky wireless connection that seemed to symbolize how fleeting human contact has become, Natalia Lafourcade smiled as she showed off her garden in Xalapa, the capital of the Mexican state of Veracruz. She had emerged from the recording studio she built there, rattling off the trees that surround her home — guayabo, higuera, mulato — as she explained the genesis of her new album, “De Todas las Flores” (“Of All the Flowers”), which bloomed in the aftermath of a romantic split. “Breakups can be so deep, at the cellular level, that you have to reconstruct your life and reconnect with yourself,” Lafourcade said as she strolled the grounds in a simple black turtleneck. “It’s difficult work, forgiving yourself, forgiving the other person,” she added. “So I went to walk in the mountains, and returned to my garden, a metaphor for a field of emotions and possibilities that had to be explored.”
