Abstract

A new and distinct variety of Buddleia plant, referred to by its cultivar name, ‘Dapconwhi’, is disclosed. The new variety forms attractive white colored flowers. Attractive, medium green colored foliage is formed. The growth habit is compact, mounded and the plant has moderate growth vigor. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name: Buddleia davidii.

Varietal denomination: ‘Dapconwhi’.

SUMMARY OF THE INVENTION

The new variety of Buddleia davidii plant originated in a controlled breeding program in Guadalupe, Calif. during June 2015. 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 self-pollination wherein seed and pollen from a single variety were used in the hope that they would contribute the desired characteristics to progeny of the self-pollination. The parent, which was both the female parent (i.e., the seed parent) and the male parent (i.e, the pollen parent) was an unnamed breeder seedling variety (not patented). The parent unnamed breeder seedling variety was created by crossing two other/different unnamed breeder seedlings varieties (neither patented).

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

The new cultivar was discovered and selected as a single flowering plant from the progeny resulting from the above stated self-pollination during July 2016 in a controlled environment in Guadalupe, Calif. Selective study resulted in the identification of a single plant of the new variety.

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

- (a) forms white colored flowers,
- (b) displays medium green colored foliage, and
- (c) exhibits a moderately vigorous and compact, mounded 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 unnamed breeder seedling parental variety displays lavender blue colored flowers and compact to upright growth habit, while the new variety provides white colored flowers and a compact, mounded growth habit. Moreover, 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 ‘SMNBDW’ variety (U.S. Plant Pat. No. 28,795), as the new cultivar displays sturdier stems and denser growth habit with new blooms that hid the old blooms as compared to the plants of the ‘SMNBDW’ 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 2016 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.

The new variety has been named ‘Dapconwhi’.

The new variety was first offered for sale on Jan. 8, 2020 at Baltimore, Md. by the inventor or by another who obtained the new variety directly or indirectly from the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows 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 photograph may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘Dapconwhi’ variety. The plant was grown in one-gallon pots for approximately four months outside at Cochranville, Pa. The plant was pinched once after transplant.

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 August 2020 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 one-gallon containers for approximately four months in an outdoor nursery in Cochranville, Pa. Plants were pinched once after transplant.
