plant named ‘SMNBDO’

A new and distinct Buddleia cultivar named ‘SMNBDO’ is disclosed, characterized by compact, dense habit less than 3 feet tall with thick, chunky stems with short internodes; heavy, wide, coriaceous, textured leaves; large and wide panicles of lilac-pink flowers; and cold hardiness. The new variety is a Buddleia, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Buddleia davidii.

Variety denomination: ‘SMNBDO’.

BACKGROUND OF THE INVENTION

The new Buddleia cultivar is a product of a planned breeding program conducted by the inventor, Timothy D. Wood, in Grand Haven, Mich., USA. The objective of the breeding program was to produce compact plants with strong branches in a range of flower colors. The cross resulting in this new variety was made during 2012.

The seed parent is the patented Buddleia davidii ‘UCONNBD610’, U.S. Plant Pat. No. 27,471. The pollen parent is the unpatented Buddleia davidii ‘Pink Delight’. The new variety was discovered in 2013 by the inventor in a group of seedlings resulting from the 2012 crossing, in Grand Haven, Mich., USA.

Asexual reproduction of the new cultivar was performed by softwood stem cuttings. This was first performed in Grand Haven, Mich., USA in 2013 and has shown that the unique features of this cultivar are stable and reproduced true to type in 6 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘SMNBDO’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SMNBDO’ These characteristics in combination distinguish ‘SMNBDO’ as a new and distinct Buddleia cultivar:

    • 1. Compact, dense plants less than three feet tall.
    • 2. Thick, chunky stems with short internodes.
    • 3. Heavy, wide, coriaceous, textured leaves.
    • 4. Large and wide panicles of lilac-pink flowers.
    • 5. Cold hardiness comparable to the most cold-hardy Buddleia davidii on the market.

Plants of the new cultivar ‘SMNBDO’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘SMNBDO’ differ in the following;

    • 1. The cultivar has a larger plant diameter.
    • 2. The new variety has smaller lateral branch lengths.
    • 3. The new variety has persistent flowers, whereas the parent has self-cleaning flowers.

Plants of the new cultivar ‘SMNBDO’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘SMNBDO’ differ in the following;

    • 1. The new variety is shorter than the pollen parent.
    • 2. The new variety has a smaller diameter than the pollen parent.
    • 3. The new variety has lilac-pink flowers whereas the pollen parent has pink flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SMNBDO’ are comparable to the unpatented commercial variety Buddleia ‘Peakeep’. The two Buddleia varieties are similar in most horticultural characteristics; however, the new variety ‘SMNBDO’ differs in the following:

    • 1. The new cultivar is a semi-dwarf, whereas the comparator is standard size.
    • 2. The new cultivar has tighter flower clusters, whereas the comparator has looser flower clusters.
    • 3. The new cultivar has panicles more horizontal/outward, whereas the comparator has panicles more upright/outward.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates a plant of ‘SMNBDO’ grown in a nursery, in a 2 gallon pot.

FIG. 2 illustrates in full color a typical inflorescence of ‘SMNBDO’. Age of the plant photographed is approximately 2-3 years old from a rooted cutting.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
