plant named ‘Orchid Annie’
Buddleia ‘Orchid Annie’ is a very short, compact, round-mounded, multi-stemmed, winter-hardy butterfly bush with long, densely-flowering, thyrse held from the soil line to the top of the plant beginning early in mid-summer and continuing over a long season until frost with sweetly-fragrant, orchid purple or red-purple flowers that are attractively offset by dark green foliage with silvery undersides.

Botanical classification: Buddleia davidii.
Variety denomination: ‘Orchid Annie’.BACKGROUND OF THE PLANT
The present invention relates to the new and distinct butterfly bush plant of the Scrophulariaceae family, Buddleia ‘Orchid Annie’ hybridized by Hans A. Hansen in the summer of 2009 at a wholesale perennial nursery in Zeeland, Mich., USA. ‘Orchid Annie’ 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 H9-47-01, is a single seedling selected from a self-pollination of Buddleia ‘Blue Chip’ U.S. Plant Pat. No. 19,991 as the female or seed patent and Buddleia ‘Blue Chip’ also as the male parent.
Buddleia ‘Orchid Annie’ was first asexually propagated from a single select plant in 2012 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.
No plants of Buddleia ‘Orchid Annie’ 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.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 ‘Orchid Annie’.
The nearest comparison plants are Buddleia ‘Blue Chip’ U.S. Plant Pat. No. 19,991, ‘Blue Chip Jr’ U.S. Plant Pat. No. 26,581, ‘Bosheven’ U.S. Plant Pat. No. 25,707 and ‘PIIBD-I’ U.S. Plant Pat. No. 26,305. Compared to the female parent, ‘Blue Chip’, the new plant is shorter and has a more red-purple or orchid purple flower color compared to the blue flowers of ‘Blue Chip’. Compared to ‘Blue Chip Jr.’ the new plant is slightly larger in habit and has a more red-purple or orchid purple flower color compared to the purple-violet of ‘Blue Chip Jr.’. Compared to both ‘Bosheven’ and ‘PIIBD-I’ the new plant is significantly shorter and more compact in habit and has a slightly lighter and more reddish red-purple or orchid purple flower color.
Buddleia ‘Orchid Annie’ 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, branched, compact, very short, round-mounded habit.
- 2. Many-flowered compact thyrse starting early and over a prolonged season beginning mid-summer and continuing until frost, from soil line to top of plant.
- 3. Sweetly fragrant flowers with orchid purple or red-purple petals.
- 4. Lanceolate foliage of dark green with silvery 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 ‘Orchid Annie’, has not been observed under all possible environments. 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.
