plant named ‘Magenta Munchkin’
Buddleia ‘Magenta Munchkin’ is a short, compact, mounded, multi-stemmed, winter-hardy butterfly bush with long, dense-flowering, outward to slightly drooping thyrse with sweetly-fragrant fuchsia-red flower faces and yellowish orange throats starting early from mid-summer until frost, from soil line to top of plant, that are attractively offset by dark green foliage with silvery white undersides.

Botanical classification: Buddleia hybrid.
Variety denomination: ‘Magenta Munchkin’.BACKGROUND OF THE PLANT
The present invention relates to the new and distinct butterfly bush plant, Buddleia ‘Magenta Munchkin’ hybridized by Hans A. Hansen in the summer of 2012 at a wholesale perennial nursery in Zeeland, Mich., USA. ‘Magenta Munchkin’ is the result of an ongoing breeding program conducted by the inventor. The goals for this program have been to produce improved, garden-worthy plants for the ornamental plant market. The new plant, originally assigned breeder code H12-109-01, is a single seedling selected from an open pollination of the proprietary unreleased hybrid named Buddleia H11-38-06 (not patented) as the female or seed parent. The male parent is unknown, but may have been from any one of several proprietary within the breeding field.
No plants of Buddleia ‘Magenta Munchkin’ have been sold, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which may have been disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor.
Buddleia ‘Magenta Munchkin’ was first asexually propagated from a single select plant in 2013 by stem cuttings at the same nursery in Zeeland, Mich. The resultant asexually propagated plants have been found to be stable and true to type in successive generations of asexual reproduction.SUMMARY OF THE INVENTION
Plants of the new Buddleia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, light intensity, available moisture and fertility without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Magenta Munchkin’.
The nearest comparison plants are Buddleia ‘Miss Ruby’ U.S. Plant Pat. No. 19,950, Buddleia ‘Miss Molly’ U.S. Plant Pat. No. 23,425 and Buddleia ‘Attraction’ (not patented). All of the above have flowers with coloration in the reddish range. All of the above are much taller and less compact than ‘Magenta Munchkin’. Compared to the new plant, ‘Miss Ruby’ has smaller inflorescences in width and length and individual flower faces are more reddish purple. Compared to ‘Miss Molly’ the new plant has much larger inflorescences and the flower faces are less in the red hue and closer to purple. The Buddleia with the nearest flower color is ‘Attraction’, but the plant habit as well as inflorescence size is much larger than the new plant.
Buddleia ‘Magenta Munchkin’ is a unique winter-hardy butterfly bush different from all other Buddleia cultivars known to the inventor based on the following combined traits:
- 1. Winter-hardy shrub, with multiple-stemmed, short, compact, round-mounded habit.
- 2. Many-flowered, dense, outward to slightly drooping thyrse starting early and over a prolonged season beginning mid-summer and continuing until frost, flowering from soil line to top of plant.
- 3. Individual flowers with flat faces of fuchsia-red and throats of yellowish orange.
- 4. Lanceolate foliage of dark green with silvery-white, canescent undersides.
The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.
The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Buddleia ‘Magenta Munchkin’, has not been observed under all possible conditions. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of two-year-old plants in the loamy-sand, open-sun, field trials of a nursery in Zeeland, Mich. with supplemental fertilizer and water as needed. The plants are natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year except to cut back woody stems to about 15 cm tall in fall or early spring to promote new growth and flowering.
