What secrets were Miguel and alfonso hiding from Esperanza and her mama

The group eats together after their first long day of work, and then Alfonso and Miguel announce a surprise. They take everyone outside behind the cabin where they have planted a few tiny rose bushes near a plastic statue of Our Lady of the Guadalupe. The rest of the family is astonished to learn that these are cuttings from Papa's roses. And, the roses for Esperanza and Miguel are there, all having survived the fire.
