Her debut at Teatro alla Scala took place in December 1842 as "Neocle" in the Italian version of "Le siège de Corinthe", which was followed by roles in operas by Marliani, Donizetti (as "Maffio Orsini" and "Leonora" in the Scala premiere of an Italian version of "La favorite"), Salvi and Pacini. In the season 1844–1845 she was engaged in the Saint Petersburg Imperial Bolshoi Kamenny Theatre; later, in 1846–47, she toured the principal cities of Central Europe, finally reaching London and Paris, where she settled permanently. In London, "she appeared in leading roles by Rossini and Donizetti (where she outshone Giulia Grisi and Jenny Lind) and also sang Cherubino (performing with Henriette Sontag)". For the 1848 London run of "Les Huguenots", Meyerbeer transposed the role of the page "Urbain" 'from soprano to contralto and composed the aria "Non! – non, non, non, non, non! Vous n'avez jamais, je gage" in Act 2' for her. On 28 August 1848, she sang at a concert in Manchester's Concert Hall, sharing the stage with Lorenzo Salvi and Frédéric Chopin. She toured the United States in 1852–53, appearing there with Camilla Urso.
