effloresce

Effloresce means to bloom or burst into flower, though the verb appears more often in technical and figurative contexts than botanical ones.

In chemistry, a substance effloresces when it loses water and forms a powdery coating on its surface.

Buildings effloresce when mineral salts migrate through masonry and crystallize as a white residue.

Figuratively, something that effloresces develops or unfolds in a flourishing way: Her talent effloresced during those formative years.
