Description

Botanical classification: Buddleja davidii

Variety denomination: ‘Botex 008’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleja davidii will be referred to hereafter by its cultivar name, ‘Botex 008’. ‘Botex 008’ is a new shrub grown for use as an ornamental landscape plant and as a container plant.

The new cultivar of Buddleja is a selection from an ongoing breeding program conducted by the Inventor in Kaatsheuvel, The Netherlands with the goal of creating new cultivars of Buddleja with very neat and compact plant habits combined with unique flower colors and floriferous blooming habits.

The Inventor made a cross in July of 2020 between unnamed and unpatented proprietary plants in the Inventor's breeding program; reference no. 19-016-01 as the female parent and reference no. 18-008-01 as the male parent. The Inventor selected ‘Botex 008’ in July of 2021 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by the Inventor using stem cuttings in Kaatsheuvel, The Netherlands in 2021. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Botex 008’ as a unique cultivar of Buddleja.

• • 1. ‘Botex 008’ exhibits a very compact, dense, and upright plant habit.
  • 2. ‘Botex 008’ exhibits flowers that are magenta purple in color.
  • 3. ‘Botex 008’ exhibits a neat and naturally overall rounded plant shape.
  • 4. ‘Botex 008’ exhibits a very floriferous blooming habit.
  • 5. ‘Botex 008’ exhibits flowers that have a pleasant fragrance.

The female parent of ‘Botex 008’ differs from ‘Botex 008’ in having slightly larger leaves and flowers that are pink-red in color. The male parent of ‘Botex 008’ differs from ‘Botex 008’ in having slightly smaller leaves, flowers that are blue-purple in color, smaller and shorter inflorescences, and a shorter plant height. ‘Botex 008’ can be compared to the Buddleja cultivars ‘Black Knight’ (not patented), ‘Botex 001’ and ‘Botex 009’. ‘Black Knight’ is similar to ‘Botex 006’ in having flowers that are purple in color. ‘Black Knight’ differs from ‘Botex 008’ in having a taller plant height, a more open plant habit, inflorescences that are less compact and longer, and flowers that are darker purple in color. ‘Botex 001’ is similar to ‘Botex 008’ in having a naturally compact and floriferous plant habit. ‘Botex 001’ differs from ‘Botex 008’ in having flowers that are blue-violet in color. ‘Botex 009’ is similar to ‘Botex 008’ in having a very compact plant habit and a naturally rounded plant habit. ‘Botex 009’ differs from ‘Botex 008’ in having a smaller plant size and flowers that are fuschsia pink in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Buddleja. The photographs were taken of a one-year-old plant as grown in a greenhouse in a 21-cm container in Kaatsheuvel, The Netherlands.

The photograph in FIG. 1 provides a side view of the overall plant habit of ‘Botex 008’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Botex 008’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Buddleja.
