Narrative

Raised from seed sown by the Abbe Duquesne, Mons, Belgium, 1809 and dedicated to Marie Loiuse, second consort of Napoleon Bonaparte. Introduced into the United States in 1823. Placed on the APS catalog list, 1862. Fruit medium in size and resembles that of Louise Bonne de Jersey in form and general appearance. Skin very smooth, greenish-yellow in color, often blushed, prominent 'trout' spots. Flesh fine, juicy, melting, quite free of grit. Very sweet with honey-like flavor. Rates among the very best in dessert quality. Early midseason. Tree fairly vigorous, not always productive. Moderately susceptible to blight. Susceptible to pear scab. Tree hardy, moderately vigorous, production varies from season to season. Not suited for commercial production, but, a choice fruit for the home garden. -- H. Hartman, 1957.
