Buganvilias are a type of vibrant, colorful flowering vine, known in English as "bougainvilleas". It's a beautiful and somewhat uncommon word that you won't find in every Spanish song.
In "De Todas Las Flores," Natalia Lafourcade uses it to create a vivid, sensory memory of a specific place: the "jardín de rosas buganvilias" (garden of roses and bougainvilleas). This beautiful setting serves as a powerful backdrop for the song's story of love and loss, making the feeling of nostalgia even more profound.
This song feels like walking through a garden after the person you love has left. Natalia Lafourcade starts with a beautiful, sad image: "De todas las flores que sembramos / Sólo quedan unas encendidas" (Of all the flowers we planted / Only a few remain lit). It's as if the love they grew together is fading, and the few flowers left are waiting for the other person to return and sing to them. The song is full of specific, sharp memories of a shared past, like being "en las calles de Madrid borrachos... sin un rumbo fijo" (drunk in the streets of Madrid... with no fixed direction) and getting lost in a special song they both understood.
But the memories are double-edged. A touch can be both "dulce como amarga" (sweet as it is bitter), and a caress can feel "suave como espina" (soft as a thorn). That feeling of melancholy, she says, is sticking into her chest. She keeps returning to the image of a garden they once shared, but the final line twists it slightly: it's no longer a place where they shared, but a place "donde nos perdimos" (where we got lost). It's a quiet, devastating shift from a shared memory to a feeling of being lost alone.
