USPP22063P2 - Buddleja plant named ‘Tobudviole’ - Google Patents

Abstract

A new cultivar of Buddleja plant named ‘Tobudviole’ that is characterized by a compact habit, short internodes, conical flower spikes, small leaves and a long flowering season.

Description

Botanical classification: Buddleja davidii.

Variety denomination: ‘Tobudviole’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleja plant botanically known as Buddleja davidii and hereinafter referred to by the cultivar name ‘Tobudviole’.

‘Tobudviole’ originated from open pollination of the female or seed parent a proprietary Buddleja identified as BUO3049 (not patented) and an unknown male or pollen parent. The resulting seeds were subsequently planted and grown. The cultivar ‘Tobudviole’ was selected by the inventor in the 2004 as a single plant in Harkstead, Ipswich, United Kingdom.

Asexual reproduction of the new cultivar ‘Tobudviole’ first occurred by terminal cuttings in 2005 in Harkstead, Ipswich, United Kingdom. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Buddleja cultivar ‘Tobudviole’. These traits in combination distinguish ‘Tobudviole’ as a new and distinct cultivar apart from other existing known varieties of Buddleja.

• • 1. Buddleja ‘Tobudviole’ exhibits short internodes.
  • 2. Buddleja ‘Tobudviole’ exhibits conical flower spikes.
  • 3. Buddleja ‘Tobudviole’ exhibits a compact habit.
  • 4. Buddleja ‘Tobudviole’ exhibits small leaves.
  • 5. Buddleja ‘Tobudviole’ exhibits a long flowering season.

The closest comparison cultivar is Buddleja ‘Nanho Purple’ (not patented).

‘Tobudviole’ is distinguishable from ‘Nanho Purple’ by the following characteristics:

• • 1. ‘Tobudviole’ has lighter purple flowers than ‘Nanho Purple’.
  • 2. ‘Tobudviole’ exhibits earlier flowering.
  • 3. ‘Tobudviole’ exhibits a longer flowering season.
  • 4. ‘Tobudviole’ has a more compact habit.
  • 5. ‘Tobudviole’ has shorter internodes.

‘Tobudviole’ is distinguishable from the female parent BUO3049 by the following characteristics:

• • 1. ‘Tobudviole’ has lighter purple flowers than BU03049.
  • 2. ‘Tobudviole’ exhibits a more compact habit.
  • 3. ‘Tobudviole’ exhibits a larger number of flowers.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Buddleja ‘Tobudviole’. The plant in the photograph shows an overall view of a 4 month old plant. The photograph was 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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Buddleja cultivar named ‘Tobudviole’. Data was collected in Mainz, Germany from 4 month plants grown outdoors in 16 cm. diameter containers. The time of year was Summer and the temperature range was 20-35 degrees Centigrade during the day and 15-25 degrees Centigrade at night. The light level was natural light. No photoperiodic treatments or growth retards were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Tobudviole’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
