The fruits of Beurré Bosc merit unqualified praise. They are nearly flawless in every character. The pears at once receive approbation from all who see them by virtue of their uniquely beautiful color and shape, in which characters they are wholly unlike any other pear. The shape is pyriform, with a very long, tapering neck, perfectly symmetrical and unequalled in trimness of contour. The color is a dark rich yellow overspread with cinnamon-russet, with here and there a spot of the yellow ground color visible. The quality is rated by all as “very good” or “best;” the Seckel alone surpasses it as a dessert fruit in the estimation of most pear fanciers. The flesh, while slightly granular, is tender and melting or almost buttery, very juicy, with a rich piquant flavor and a pleasing aroma. The fruits seldom crack, scab, or mildew. The characters of the tree fall far short of those of the fruits. Nurserymen complain that it is difficult to propagate the trees as they make a poor growth in the nursery and come to transplanting age with a root system of two or three prongs almost devoid of fibrous roots. The trees must be humored in soil and climate, and under favorable conditions make but moderate growth as young plants. Established trees in suitable soils, however, surpass most of their neighbors in size and luxuriance of foliage. Very old trees have a nobility of aspect possessed by few other pears. While slow in coming in bearing, after fruiting begins the trees bear regularly and abundantly. The variety does not succeed well on the quince unless double-worked. Unfortunately, the trees are tender to cold and somewhat too susceptible to blight. Beurré Bosc has long been a favorite in the pear regions of Europe and America, and its culture in this country may be recommended for the home, for local and general markets, and for exportation.
This pear is a native of Belgium, having been raised from seed in 1807 by Dr. Van Mons, the renowned pomologist of Louvain, and was in the first instance named by him Calebasse Bosc in honor of M. Bosc, a distinguished French naturalist. In 1820, it was received at the garden of the Horticultural Society of London under the name Beurré Bosc, and Robert Thompson, at that time Director of the gardens, thought it best to retain this name. The variety was early introduced into France. About 1832 or 1833, Robert Manning and William Kenrick received cions in the United States from Van Mons and from the London Horticultural Society. The variety was cataloged by the American Pomological Society at its first meeting in 1848.
