JACKSON GROVE Cornell Plantabons Plant List Last Updated 7/31/12 Magnolia Collection Common Name Scientific Name Magnolia × brooklynensis 'Black Beauty' MAGNOLIA Magnolia ×brooklynensis 'Hattie Carthan' MAGNOLIA Magnolia ×brooklynensis 'Woodsman' MAGNOLIA Magnolia ×kewensis 'Wada's Memory' MAGNOLIA Magnolia ×loebneri 'Merrill' LOEBNER MAGNOLIA 1 Notes Flowers are a very dark purple, the same shade as the "black" Tulips, and chalk-‐white interiors serve to highlight the dark exteriors. Flowers appear in late April and through much of May. Small tree with a narrow habit with parchment yellow flowers subtly striated with magenta and having a delightful fragrance. The flowers have unusually heavy substance and appear with the earliest leaves in late April and May, so late that there is less chance of frost damage. Buds the color of bittersweet chocolate open to reveal multi-‐hued flowers of purple, chartreuse, and rose. Its pastel shades are complementary, never garish. Flowering is delayed until early May, so late frosts are almost never a problem. Vigorous, rapid grower with fastigiate form; very hardy. Blooms when only 2' tall, and is floriferous. White flowers are larger than those of M. kobus (DS 175). Selected by Brian Mulligan at the University of Washington, Seattle, WA from a group of seedlings obtained from Mr. K. Wada of Yokohama, Japan. (DS 175 & DS 28). Strong growing; flowers with 15 petals, somewhat larger than those of M. stellata, petals also twice as wide (DS 6). A free-‐ flowering form; flowers 3" to 3 1/2" across with 15 white petals, borne in late April; magnificent in flower. Common Name Scientific Name Magnolia acuminata 'Skylands' Best' CUCUMBER TREE Magnolia 'Elizabeth' AGM MAGNOLIA Magnolia 'Flamingo' MAGNOLIA Magnolia 'Golden Gift' MAGNOLIA Magnolia 'Jon Jon' MAGNOLIA Magnolia kobus 'Borealis' KOBUS MAGNOLIA (JAPAN) Magnolia 'Limelight' MAGNOLIA Magnolia 'Porcelain Dove' MAGNOLIA 2 Notes A repeat flowering yellow Magnolia from the Skylands Botanical Garden in New Jersey. This selection has unusually large yellow flowers, 6 inches across, which appear in late spring with repeat bloom in late summer. Leaves are dark green and especially handsome. Neat, pyramidal habit. Finely tapering flower buds open to display flowers of the clearest primrose-‐yellow. Blooming season April through mid-‐May at the Brooklyn Botanic Garden (DS 9). Flowers have pleasant fragrance (DS 175). Brilliant unfading flamingo-‐pink flowers open just before leaves emerge on a pyramidal tree from the late Phil Savage. The flowers have a tulip shape which is retained until shattering. (M. acuminata 'Fertile Myrtle' x M. sprengeri 'Diva'.) A yellow magnolia of smaller stature, reaching only 6' wide by 8' tall in 10 years. Flowers are a strong yellow, and they are produced in multiple terminal buds and even axillary buds from the trunk all the way to the tips of the branches, so that the plant in bloom is a globe of yellow. Flowers keep opening for about 4 weeks. White flowers washed with rose tints at the base open in late April and early May. The blooms are very fragrant and quite large, measuring 10-‐12" across. A smallrounded tree with excellent branching habit. A hardy form which is more vigorous and reaches larger sizes that the type. Plants upright, reaching 15'-‐18' in height; flowers are pale yellow-‐green to cream. A mostly deciduous small tree with heaviest bloom in June and additional flowers apppearing throughout the summer. The 4" white flowers open in late afternoon to reveal a ring of rich red stamens. Flowers have a good fragrance. A hybrid of Magnolia globosa with M. virginiana. Common Name Scientific Name Magnolia 'Rose Marie' MAGNOLIA Magnolia salicifolia ANISE MAGNOLIA Magnolia salicifolia 'Miss Jack' ANISE MAGNOLIA Magnolia sieboldii small flowered magnolia Magnolia 'Sunsation' MAGNOLIA Magnolia 'Sunspire' MAGNOLIA Magnolia tripetala Magnolia 'Yellow Lantern' UMBRELLA MAGNOLIA MAGNOLIA 3 Notes Large flowers with broad tepals open wide displaying a brilliant rosy pink on the exterior, and this vivid color carries through to the interior in shades of medium pink. Flowering begins late, avoiding most frosts, and can continue for up to six weeks. The tree blooms at a young age and is particularly floriferous. (M. 'Pink Surprise' x M. 'Daybreak'). Slender, rather narrowly pyramidal tree reaching 20-‐30' in height. Flowers are pure white, fragrant, 3-‐4" in diameter, and are composed of 6 petals which open in April before the leaves. The stems when bruised emit a pleasant lemon scent. Narrow foliage is anise-‐scented. The white flowers are produced in great numbers. Deciduous tree or shrub reaching 20' in height with light gray bark. Leaves obovate or elliptic, 2"-‐6" long and 2"-‐4" wide with an acute apex and cuneate or rounded base, the upper surface dark green, the lower light green with yellowish pubescence. Flowers white, fragrant, saucer-‐shaped, nodding or pendent with 9-‐12 obovate tepals; stamens showy magenta; outer seed coats bright red. Tree with yellow flowers with a noticable pink untertone which enhances the yellow. Deep yellow flowers are produced on a small columnar tree . Flowers bloom late enough to avoid nearly all frosts. Tree similar to M. macrophylla, reaching 15' to 30' (to 40') in height. Leaves reach 10" to 24" in length and are clustered near the ends of the branches, creating an umbrella effect. Flowers are 6" to 10" across, solitary, unpleasantly scented, borne in May and early June (before those of M. macrophylla). Fruits are 4" long, elongated, cone-‐shaped, rosy-‐ red, maturing in September and October. Upright, single-‐stemmed tree; flower buds are large, tomentose, opening to a uniform lemon-‐yellow, cup-‐shaped flower similar in form and size to that of 'Alexandrina', the color is without any greenish tinges; plants bloom at a young age.

Deciduous tree reaching 80' in height; leaves variable in shape, usually oblong to elliptic, to 6" long, with 3 to 5 pairs of bristle-‐tipped lobes, or nearly entire, glabrous beneath except for tufts of hairs in axils of veins (DS 3). A naturally occuring hybrid found where the ranges of Q. macrocarpa and Q. bicolor overlap. Plants of medium growth rate, reaching 70' with a densely rounded crown, and producing large, low-‐tanin acorns. Suggested as a good choice for wildlife feed. A dense, broad pyramid in youth, varying in old age from oval-‐rounded to broad-‐rounded with low-‐slung, wide-‐spreading branches. Plants reach 35' to 45' in height with variable width. Foliage opens a brilliant yellow to golden-‐yellow in spring, becoming deep lustrous green in summer, often developing a good clear yellow to golden brown fall color, late, often in November. Plants form broad, open, round-‐topped crown with a short, limby trunk; 50-‐60' tall with an equal or greater spread. Bark flaky, grayish-‐brown, divided by deep longitudinal fissures into rather long flat ridges. Pyramidal to upright-‐oval in youth, assuming a broad-‐rounded outline in old age, often with drooping lower lateral branches; plants reach 50' to 60' in height (can attain 80' to 100') with an equal or greater spread. Tall tree, reaching 25 to 30 m; young shoots glabrous; leaves obovate to obovate-‐oblong, 10 to 20 cm long,fruits ovate, 2 cm long, nearly sessile, acorns 1/3 covered by a thick cup, scales warty, the apical ones fringed-‐ acuminate. Common Name Scientific Name Quercus montana CHESTNUT OAK Quercus palustris PIN OAK Quercus robur ENGLISH OAK Quercus rubra RED OAK Quercus shumardii SHUMARD RED OAK 5 Notes Rounded, relatively dense tree reaching 60' to 70' in height with a comparable but irregular spread. Leaves 4"-‐6" long, 1.5"-‐3.5" wide, ovate to obovate-‐oblong, acute or acuminate, cuneate or rounded at base, coarsely and irregularly toothed with 10-‐14 pairs of obtuse, often mucronate teeth, lustrous dark yellow-‐green above, grayish tomentulose beneath. Fall color orange-‐ yellow to yellow-‐brown. Acorns sweet. Strongly pyramidal tree, usually with a central leader, the lower branches pendulous, the middle horizontal and the upper upright; in old age the tree assumes an oval-‐pyramidal form and loses many of the lower branches; plants reach 60' to 70' in height, 25' to 40' in width; can attain over 100' in height. Foliage dark glossy green in summer, assuming russet, bronze or red fall color. Suffers from iron chlorosis in high pH soils. Large, massive, broadly rounded, open-‐ headed tree with a short trunk; in youth pyramidal to rounded; can reach 75' to 100' or more in height with a comparable spread. In the U.S.A. it averages 40' to 80' in height under landscape conditions. Rounded habit in youth, in old age often becoming round-‐topped and symmetrical; relatively fast growing (can grow 2' per year over a 10 year period). Fall color russet-‐red to bright red. Plants 60-‐75' tall, 40-‐50' wide, although can attain over 100' in height in the wild. Pyramidal tree in youth becoming more wide-‐ spreading at maturity much like Q. coccinea that reaches 40-‐60' in height in landscape situations, to 100' in the wild. Difficult to separate from Q. palustris and Q. coccinea except by winter buds which are gray to straw-‐colored never reddish brown. Fall color varies from a good russet-‐red to yellow-‐ bronze or faint reddish-‐brown. Acorns are ovate, 3/4-‐1" long, short-‐stalked, and covered only at the base by a hemishperical involucral cap.
