Description

Genus and species: Buddleia davidii.

Variety denomination: ‘TMBU08-3’.

BACKGROUND OF THE INVENTION

‘TMBU08-3’ is a product of a breeding and selection program for ornamental Buddleia varieties to be vegetatively propagated. The new plant of the present invention comprises a new and distinct cultivar of Buddleia plant.

‘TMBU08-3’ is a seedling resulting from the open-pollination of several varieties of Buddleia davidii. Seed was bulk collected, without identification of the exact parents. The open-pollination resulting in this new variety was conducted in August of 2014 in Suffolk, UK. The selection of the new variety was made in August of 2015, by the inventor at a research greenhouse located in Suffolk, UK.

‘TMBU08-3’ was first asexually reproduced by terminal vegetative cuttings at a greenhouse in Suffolk UK, August 2015 and has been asexually reproduced over an approximately three-year period. The new cultivar has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices:

    • 1. Upright plant habit.
    • 2. White flowers.
    • 3. Light Greyed-green foliage.
    • 4. Medium mature height.
    • 5. Slow growing.

COMPARISON WITH PARENT VARIETIES

The parent varieties are unidentified.

COMPARISON WITH COMMERCIAL CULTIVARS

‘TMBU08-3’ can be compared to the commercial variety ‘Tobudivory’, unpatented. Plants of the two varieties are similar in most horticultural characteristics, however, ‘TMBU08-3’ differs in the following:

    • 1. Plant form of the new variety is more upright and less spreading than that of ‘Tobudivory’.
    • 2. Foliage of the new variety is lighter greyed-green than foliage of this comparator.

‘TMBU08-3’ can be compared to the commercial variety ‘White Ball’, unpatented. Plants of the two varieties are similar in most horticultural characteristics, however, ‘TMBU08-3’ differs in the following:

    • 1. Plant form of the new variety is more upright and less spreading than that of ‘White Ball’.
    • 2. Plant height of the new variety is taller than plant height of ‘White Ball’.

DESCRIPTION OF THE PHOTOGRAPHS

The present invention of a new and distinct variety of Buddleia is shown in the accompanying photographs, the colors being as nearly true as possible with color photographs of this type.

FIG. 1 illustrates a plant of approximately 18 months in a 3 gallon pot

FIG. 2 illustrates a close up of the inflorescence.

 DESCRIPTION OF THE INVENTION

This new variety of Buddleia is of the botanical classification Buddleia davidii. The observations and measurements were gathered from plants grown outdoors in Camarillo, Calif. under natural light, natural day length and temperatures. Measurements were taken during April.

The following is a description of the plant and characteristics that distinguish ‘TMBU08-3’ as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is The Royal Horticultural Society color chart, edition 2007.
