Nut Tree Collection Cornell Plantations Plant List Last Updated 8/3/12 scientific name common name Acer pictum PAINTED MAPLE Carya 'Cornell' HICKORY Castanea mollissima CHINESE CHESTNUT Castanea mollissima 'Kuling' CHINESE CHESTNUT 1 notes Trees to 20 m tall. Bark gray. Fruit yellowish when mature; nutlets flat, compressed, 1-‐1.3 cm × 8-‐10 mm; wing oblong, including nutlet 3-‐3.5 × 1-‐1.5 cm, wings spreading variously. Fl. Apr-‐May, fr. Sep. 2n = 26. Forests, usually in valleys, also cultivated; sea level to 3300 m. John Brittain of Nolin River Nut Tree Nursery, Upton, KY, and Brian Caldwell who has a nut tree orchard in West Danby, NY feel this tree is an exceptional producer of good quality nuts. However, they agree it is not 'Burton' nor is it a Hican (pecan X shagbark or shellbark). Their guess is it is a shagbark X shellbark hybrid. Tree with round habit in youth, developing a rounded to broad-‐rounded outline at maturity, usually low-‐branched; trees reach 40' to 60' in height with an equal spread. Foliage reddish when expanding, changing to a lustrous dark green in summer, assuming shades of yellow and bronze in fall. Flowers pale yellow or creamy, with heavy, unpleasant odor. Fruit a nut, 2 to 3 enclosed in a prickly involucre which splits at maturity into 2 to 4 valves; seed-‐grown trees often produce fruit after 4 to 5 years. Tree more upright in form than most Chinese chestnut trees; nuts dark brown and average 35 to 40 per pound.

Bark gray. Fruit yellowish when mature; nutlets flat, compressed, 1-‐1.3 cm × 8-‐10 mm; wing oblong, including nutlet 3-‐3.5 × 1-‐1.5 cm, wings spreading variously. Fl. Apr-‐May, fr. Sep. 2n = 26. Forests, usually in valleys, also cultivated; sea level to 3300 m. Densely pyramidal to oval or rounded tree, branching to the ground, reaching 50' to 60' in height, 35' to 45'in width; can attain 100' in height. Foliage unfolds a shimmering green, gradually changing to lustrous dark green in the summer, and assuming rich russet and golden bronze colors in the fall. Bark smooth gray, usually darker than that of F. grandifolia, developing an elephant hide appearance on older trunks; extremely attractive. Tree reaching 60' in height; leaflets 11 to 16, 6" long, pubescent beneath; fruit broadly ovoid to nearlyglobose, 1 1/2" long, sticky-‐ pubescent, nut ovoid, pointed, rugose, thick-‐ shelled. Nut cordate or cordate-‐ovoid, flattened, relatively thin-‐shelled, with shallow groove on each side. Along with 'Wright', one of the best heartnut selections. Nuts relatively large, and crack easily. Large nut clone that reportedly posesses resistance to dieback. Little else known Nuts large, with good flavor and cracking quality; trees productive, bearing at 2 to 3 years of age. Large tree reaching 50' to 75' (125' to 150') in height, often with a similar spread when grown in theopen, usually developing a full, well-‐formed trunk which is devoid of branches for a considerable distance(1/2 to 2/3's) from the ground. The crown is oval to rounded and somehwat open. Large tree reaching 50' to 75' (125' to 150') in height, often with a similar spread when grown in the open, usually developing a full, well-‐formed trunk which is devoid of branches for a considerable distance (1/2 to 2/3's) from the ground. The crown is oval to rounded and somehwat open. Leaflets are finely dissected.

Bark gray. Fruit yellowish when mature; nutlets flat, compressed, 1-‐1.3 cm × 8-‐10 mm; wing oblong, including nutlet 3-‐3.5 × 1-‐1.5 cm, wings spreading variously. Fl. Apr-‐May, fr. Sep. 2n = 26. Forests, usually in valleys, also cultivated; sea level to 3300 m. 'Mintle' has shown exceptional survival in plantings; nuts have outstanding total kernel percentage and high first-‐crack kernel percent. Grows up to 150 feet, bark is black, thick and deeply furrowed. Leaves also when crushed have a distinct "walnut" smell. Flowers are yellow-‐green like a birch tree. Fruits can be found either single or in groups of 2 or 3. They are spherical in shape and about 2 inches in diameter. Walnut husks are yellow-‐ green, when young and darken with age and black when on the ground. A highly productive selection that bears large nuts with high quality, light colored kernels that separate cleanly from the outer hull. Trees have produced good crops in test plantings in TN; shows high survival in propagation; nuts have an exceptionlly high total kernel percent. A vigorous, early-‐bearing tree with some tendency towards alternate bearing. It is the most widelyplanted cultivar for commercial nut production. Nuts have high total kernel percent; a well-‐known cultivarthat is often used as a standard for comparison when evaluating new selections. 'Thomas' has lost favor in IL, IN, MO, and OH because of frequent summer defoliation and poor nut filling. It still rates high in PA and other East Coast states. Outstanding selection known for its high nut and kernel weight, and resistance to anthracnose leaf spot. 53% kernel; small, well-‐flavored nut similar to 'Hansen', but usually reported to be less productiveand winter hardy. Acer pictum PAINTED MAPLE Juglans regia 'Gligor #3' ENGLISH WALNUT Juglans regia 'Hansen' CARPATHIAN WALNUT Trees to 20 m tall. Bark gray. Fruit yellowish when mature; nutlets flat, compressed, 1-‐1.3 cm × 8-‐10 mm; wing oblong, including nutlet 3-‐3.5 × 1-‐1.5 cm, wings spreading variously. Fl. Apr-‐May, fr. Sep. 2n = 26. Forests, usually in valleys, also cultivated; sea level to 3300 m. Large desiduous tree, height of 25-‐35 m, trunk 2 m in diameter, short trunk and broad crown. Bark is smooth, olive-‐brown when young and silvery-‐grey when older. Leaves are alternately arranged. The whole fruit, including the husk, falls in the autumn; seed is large, with thin shell, and edible with a rich flavor. A relatively small, winter hardy, self-‐ pollinating tree that is adpated to a wide range of growing conditions;however, shoot growth starts early in the spring. Annual bearer, producing small, thin-‐shelled nuts Juglans regia 'Lake' CARPATHIAN WALNUT Pterocarya stenoptera CHINESE WINGNUT 4 withthe highest percent kernel of any variety. Trees reported to yield well in southern IL and MO, producing nuts of good size, flavor and appearance,with 50% kernel; no data on hardiness is available. Tree reaching 15 to 25 (30) m in height, young shoots with dense brown-‐yellow pubescence or nearly glabrous; leaves 20 to 40 cm long, rachis winged, the wing margins usually serrate (!), leaflets 11-‐21, terminal leaflets often absent, narrowly oblong, 4 to 10 cm long, finely serrate, venation and midrib on theunderside lightly pubescent; fruit clusters 20 to 30 cm long, fruits with oblong, erect (!) wings, these withthe nutlet 1.5 to 2 cm long.
