Abstract

A new and distinct cultivar of Magnolia tree named ‘MJK-MC1’, characterized by its upright and columnar in overall tree form; moderately vigorous growth habit and moderate growth rate; relatively large caliper trunk; freely branching habit with numerous lateral branches providing a full and densely foliated appearance; sturdy, thick, leathery and durable green-colored leaves that resist biotic and abiotic damage; late bud break which reduces late frost damage to flowers and leaves; flowering on first year's growth; freely flowering habit with numerous large white and reddish purple-colored flowers; and good landscape performance and cold hardiness.

Description

Botanical designation: Magnolia cylindrica.
Cultivar denomination: ‘MJK-MC1’.
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT
The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant. Inventor/Applicant claims a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of deciduous Magnolia tree, botanically known as Magnolia cylindrica, commercially referred to as the Huangshan Magnolia and hereinafter referred to by the name ‘MJK-MC1’.
The new Magnolia tree originated from an open-pollination in Stayton, Oreg. in 1999 of an unnamed selection of Magnolia cylindrica, not patented, as the female, or seed, parent with an unknown selection of Magnolia cylindrica as the male, or pollen, parent. The new Magnolia tree was discovered and selected by the Inventor as a single plant from within the progeny of the stated open-pollination in a controlled environment in Stayton, Oreg. in July, 2002.
Asexual reproduction of the new Magnolia tree by grafting on Magnolia kobus rootstock in a controlled greenhouse environment in Stayton, Oreg. since May, 2015 has shown that the unique features of this new Magnolia tree are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Trees of the new Magnolia have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MJK-MC1’. These characteristics in combination distinguish ‘MJK-MC1’ as a new and distinct Magnolia tree:
    • 1. Upright and columnar in overall tree form; lateral branches relatively short and stout.
    • 2. Moderately vigorous growth habit and moderate growth rate.
    • 3. Relatively large caliper trunk.
    • 4. Freely branching habit with numerous lateral branches providing a full and densely foliated appearance.
    • 5. Sturdy, thick, leathery and durable green-colored leaves that resist biotic and abiotic damage.
    • 6. Late bud break which reduces late frost damage to flowers and leaves.
    • 7. Flowering on first year's growth.
    • 8. Freely flowering habit with numerous large white and reddish purple-colored flowers.
    • 9. Good landscape performance and cold hardiness.
Trees of the new Magnolia can be compared to trees of the female parent selection. Trees of the new Magnolia differ primarily from trees of the female parent selection in the following characteristics:
    • 1. Trees of the new Magnolia are narrower and more columnar than trees of the female parent selection.
    • 2. Trees of the new Magnolia flower on first year's growth whereas trees of the female parent selection do not start flowering until about seven years after propagation.
    • 3. Trees of the new Magnolia are more freely flowering than trees of the female parent selection.
    • 4. Trees of the new Magnolia are relatively more resistant to pathogens and pests common to Magnolias than trees of the female parent selection.
Trees of the new Magnolia can be compared to trees of Magnolia x soulangiana ‘Galaxy’, not patented. In side-by-side comparisons, trees of the new Magnolia and ‘Galaxy’ differ primarily in the following characteristics:
    • 1. Trees of the new Magnolia are columnar and dense whereas trees of ‘Galaxy’ are more open and sparse.
    • 2. Trees of the new Magnolia have strong and straight trunks whereas trees of ‘Galaxy’ have weak trunks and require staking to grow upright.
    • 3. Bud break of trees of the new Magnolia is later than bud break of trees of ‘Galaxy’ which reduces late frost damage to flowers and leaves.
    • 4. Flowers of trees of the new Magnolia are white and reddish purple in color whereas flowers of trees of ‘Galaxy’ are light lavender in color.
    • 5. Trees of the new Magnolia are more resistant to pathogens and pests common to Magnolias than trees of ‘Galaxy’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Magnolia tree showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the second sheet (FIG. 2 ) is a side perspective view of a typical flowering mature tree of ‘MJK-MC1’ grown during the spring.
The photograph on the third sheet (FIG. 3 ) is a close up view of typical leaves of ‘MJK-MC1’.
The photograph on the fourth sheet (FIG. 4 ) is a close-up view of typical flowers of ‘MJK-MC1’.
The photograph on the fifth sheet (FIG. 5 ) is side perspective views of typical flowers of ‘MJK-MC1’.
 DETAILED BOTANICAL DESCRIPTION
