plant named ‘Conbud2080’

Abstract

A new and distinct variety of Buddleia plant, referred to by its cultivar name, ‘Conbud2080’, is disclosed. The new variety displays purple-rose colored flowers and dark green colored foliage. Attractive moderately vigorous vegetative is formed. The growth habit is compact and well-branched. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Buddleia davidii.

Variety denomination: ‘Conbud2080’.

BACKGROUND OF THE INVENTION

The new variety of Buddleia davidii plant originated in a controlled breeding program in Guadalupe, Calif. during June 2016. The objective of the breeding program was the development of a series of Buddleia cultivars with compact and well-branched habits. The new cultivar was created by cross-pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was an unnamed breeder seedling variety (not patented). The male parent (i.e., the pollen parent) was a different unnamed breeder seedling variety (not patented).

The parentage of the new variety can be summarized as follows:
unnamed breeder seedling x different unnamed breeder seedling

The new cultivar was discovered and selected as a single flowering plant from the progeny resulting from the above-stated cross-pollination during July 2017 in a controlled environment in Guadalupe, Calif. Selective study resulted in the identification of a single plant of the new variety.

The new variety has been found to undergo asexual propagation by terminal stem cuttings. Asexual propagation by terminal stem cuttings in Guadalupe, Calif. since August 2017 has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of Buddleia plant of the present invention:

• • (a) forms purple-rose colored flowers,
  • (b) displays dark green colored foliage, and
  • (c) exhibits a moderately vigorous, compact, and well-branched growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the female parent unnamed breeding seedling (i.e., the seed parent) displays grey-sliver colored foliage and medium lavender colored flowers, whereas the new variety provides dark green colored foliage and purple-rose colored flowers. The male parent which is a different unnamed breeder seedling (i.e., the pollen parent) displays medium green colored foliage and dark purple-violet colored flowers, whereas the new variety displays dark green colored foliage and purple-rose colored flowers.

The new variety can also be distinguished from other similar varieties that are commercially available. For instance, the new variety of the present invention can readily be distinguished from the ‘Boscranz’ variety (U.S. Plant Pat. No. 25,730), as the new cultivar displays a more compact growth habit, as compared to plants of the ‘Boscranz’ variety. In addition, the ‘Boscranz’ variety forms dark cranberry colored flowers, whereas the new variety forms purple-rose colored flowers.

The new variety has been named ‘Conbud2080’.

The new variety was first sold in April 2021 by the inventor or by another who obtained the new variety directly or indirectly from the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant and plant parts of the new variety. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘Conbud2080’ variety. The plants were grown in three-gallon pots for approximately one year outside at Cochranville, Pa. Plants were pinched once after transplant. Photographs were taken in August 2018.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Color Chart), 2015 edition, London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The color values were determined in July 2021 under natural light conditions in Cochranville, Pa. The description is based on the observation of plants produced from cuttings from stock plants and grown in three-gallon containers for approximately one year in an outdoor nursery in Cochranville, Pa. Plants were pinched once after transplant.
