This selection of the Southern Magnolia was selected from a field of seedlings at Cherry Lake Tree Farms in Groveland, Florida. It is a pyramidal/oblong shaped tree with a dominant central leader and develops scaffold branching with wide branch angles, eliminating embedded bark at older ages. Ultimate height is not yet known, but at 10 years from seed the original plant is 18–20 feet tall and 12 feet wide. The thick lustrous green leaves are 7–9 inches long and 3–4 inches wide with an elliptical-oblong shape.

The leaf margins are entire and wavy, acutely rounded at the apex. The plant flowers at an early age, and has flowers that seem more fragrant than typical. Flower size is from 10–12 inches in diameter with 10 petals. The receptacle, where the stamens were attached, is red-purple (RHS 61B). This is best visible just after the petals have faded. Fruit cones are plump, 4 inches tall. Beginning in late summer they turn wine-burgundy before the cones dehisce to present dark red seeds. This selection will be patented, and the name Miss Chloé(tm) is a trademark of Cherry Lake Tree Farms.

]M. acuminata], cv. (Magnolia 29(2) [Issue 56]: 22, 1994). `This cultivar was selected from the wild in Avert, Missouri (Stoddard County), on Crowley's Ridge by Richard B. Figlar. This plant conforms to the description of M. acuminata var. ozarkensis published by Hardin in 1954. It differs from typical M. acuminata in having broadly elliptic and subglossy leaves. Many leaves of `Crowley's Ridge’ are almost round with an abrupt pointed (rather than acuminate) leaf apex, with wavy margins. Flowers are smaller than typical and appear a glaucous blue in bud. This form grows faster and has a more pendulous branching habit than typical, and the secondary veins in the leaves are more prominent. Leaf backs are sparsely pubescent and light green, differing from the pubescent glaucous leaf undersurfaces in typical M. acuminata. The fruit of this cultivar is pictured in Plate 1 of Callaway's The World of Magnolias. Figlar reports that var. ozarkensis has largely been extirpated from the wild.

Ultimately the tree grows to a large spreading form with considerable branching. It differs from typical M. grandiflora in having bright white flowers with 12 tepals, and in having medium green leaves with little or no indumentum on the undersurfaces. It is not as hardy as some grandiflora clones, but should be hardy to zone 6B. Registered by Figlar in June, 1994.’
