The variety originated about 1851 on the farm of a Dr. Marvin, Morristown, New Jersey. Of its parentage nothing is known. Mountain Rose has always been considered a good market variety and has been widely disseminated. The American Pomological Society added this peach to its fruit-list in 1871, a place it has since held.
MOUNTAIN ROSE
Tree large, vigorous, upright-spreading, low-growing and dense-topped, rather unproductive; trunk thick, medium in smoothness; branches stocky, smooth, reddish-brown covered with light ash-gray; branchlets thick, long, with internodes of medium length, dark red intermingled with olive-green, glossy, smooth, glabrous, with numerous conspicuous, large and small lenticels raised near the base.
Leaves six and three-fourths inches long, one and five-eighths inches wide, flattened or curled downward, oval to obovate-lanceolate, thick, leathery; upper surface dull, dark green; lower surface grayish-green; apex long-acuminate; margin finely serrate, tipped with reddish-brown glands; petiole seven-sixteenths inch long, with two to four small, globose, reddish-brown glands variable in position; flower-buds conical to pointed, plump, very pubescent, usually appressed; blossoms appear in mid-season; flowers small.
Fruit matures in early mid-season; two and one-eighth inches long, two and one-fourth inches wide, roundish-oblate to slightly cordate; cavity intermediate in depth and width, flaring to abrupt, often twig-marked; suture shallow, becoming deeper toward the tip; apex roundish, depressed in the suture, with mucronate or sometimes mamelon tip; color creamy-white blushed with deep red, with a few splashes of darker red; pubescence long, thick; skin thin, tough, variable in adhesion; flesh white, stained red near the pit, juicy, tender and melting, sweet, mild, pleasantly flavored; good to very good in quality; stone free, one and one-fourth inches long, seven-eighths inch wide, oval to ovate, plump, bulged on one side, contracted toward the base, tapering to a short point, usually with small pits in the surfaces; ventral suture deeply grooved along the sides, furrowed; dorsal suture grooved, faintly winged.

As a rule, peaches originating in California find small favor in New York. California peaches are selected for canning, evaporating and shipping, whereas New York varieties are dessert fruits. Muir is a California sort suitable only for culinary purposes—attractive enough inside but so unattractive externally that it could tempt no one who did not know the fruit to be sweet and delicious in flavor. It is a late mid-season, yellow-fleshed, freestone peach much used by canners on the Pacific slope. It ought to be more generally grown for the same purpose in the East; for, as a canned product, it is hardly surpassed in appearance or quality. The trees are vigorous, productive and little subject to leaf-curl but the fruits in New York are often marred by peach-scab. The variety seems perfectly at home in this State as, seemingly, it is in most peach-regions. In fruit-characters, Muir is very similar to Wager.
The variety was found more than twenty-five years ago on the farm of John Muir, near Silveyville, California. G. W. Thissell, Winters, California, named and introduced Muir. The American Pomological Society added this peach to its fruit-list in 1899.
