plant named ‘Centennial Blush’

A new Magnolia plant variety, ‘Centennial Blush’, is provided. ‘Centennial Blush’ is a new and distinct cultivar of the plant Magnolia stellata, which is characterized by dense conical pyramidal habit, large 12 to 14 cm wide flowers composed of 46 tepals, flower bud development at most nodes resulting in heaviest flowering of any known varieties of Magnolia stellata, and ability to set numerous flower buds as a 2 to 3-year-old plant.

Description

Latin name of the genus and species of the plant claimed: ‘Centennial Blush’ is a Magnolia plant of the species Magnolia stellata.

Variety denomination: The new Magnolia plant claimed is of the variety denominated ‘Centennial Blush’.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of the plant Magnolia stellata, hereafter referred to as ‘Centennial Blush’, as herein described and illustrated.

The new Magnolia plant originated from open-pollinated seed of ‘Centennial’ (unpatented). The original plant is a conical-pyramidal, full flower plant about 10 years old and 3.6 m by 1.8 m in size. The seedlings were planted in containers and selections were made in March 2010 at former College Station Hydrangea Garden in College Station, Tex.

Asexual reproduction by traditional cuttings has shown that the distinguishing characteristics of this new variety ‘Centennial Blush’ are stable and reproduced true-to-type in successive generations.

SUMMARY OF THE INVENTION

The new Magnolia plant variety ‘Centennial Blush’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 distinct characteristics of the new Magnolia plant variety ‘Centennial Blush’:

    • 1. Dense conical pyramidal habit.
    • 2. Large, 12 to 14 cm wide flowers composed of 46 tepals.
    • 3. Flower bud development at most nodes resulting in heaviest flowering of any known varieties of Magnolia stellata.
    • 4. Ability to set numerous flower buds as a 2 to 3-year-old plant.

Compared to other varieties of Magnolia stellata, the new plant variety ‘Centennial Blush’ displayed heavier flowering with flower bud development at most nodes. Compared to ‘Centennial’ (28 to 32 tepals) and ‘Lyle's Legacy’ (about 29 tepals) per flower, the new variety ‘Centennial Blush’ had more tepals (46 tepals) per flower.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic illustrations show typical specimens of the new variety ‘Centennial Blush’. The colors are as nearly true as is reasonably possible in a color representation of this type.

FIG. 1 is a photograph of the new variety ‘Centennial Blush’.
