plant named ‘Podcept1’

Abstract

A new cultivar of Buddleia plant named, ‘Podcept1’, that is characterized by its short branch internodes, its double, semi-double flowers, and single flowers, its short plant height, its early blooming habit, its numerous inflorescences relative to its plant size, and its inflorescences with semi-indeterminate flowering.

Description

Botanical classification: Buddleia davidii x Buddleia alternafolia.

Variety denomination: ‘Podcept1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleia davidii x Buddleia alternafolia and will be referred to hereafter by its cultivar name, ‘Podcept1’. ‘Podcept1’ is a new shrub grown for use as an ornamental landscape plant.

The new cultivar of Buddleia is a selection from an ongoing breeding program conducted by the Inventor in Salem, Oreg. with the objective of creating new cultivars of Buddleia (syn. Buddleja) with dwarf plant habits and reduced fertility.

The new variety of Buddleia, ‘Podcept1’, arose from gamma irradiation of seeds collected from unnamed proprietary plants (not patented) of Buddleia davidii x Buddleia alternafolia in 2014. The exact parent plants are unknown. ‘Podcept1’ was selected from amongst the resulting seedlings as a single unique plant in 2015.

Asexual propagation of the new cultivar was first accomplished by the Inventor using stem cuttings in Salem, Oreg. in 2015. Asexual propagation by stem cuttings and tissue culture 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 ‘Podcept1’ as a unique cultivar of Buddleia.

• • 1. ‘Podcept1’ exhibits short branch internodes.
  • 2. ‘Podcept1’ exhibits double, semi-double flowers, and single flowers.
  • 3. ‘Podcept1’ exhibits a short plant height.
  • 4. ‘Podcept1’ exhibits an early blooming habit.
  • 5. ‘Podcept1’ exhibits numerous inflorescences relative to its plant size.
  • 6. ‘Podcept1’ exhibits inflorescences with semi-indeterminate flowering.

‘Podcept1’ can be compared to the Buddleia cultivars ‘Blue Chip’ (U.S. Plant Pat. No. 19,991) and ‘Podaras #9’ (U.S. Plant Pat. No. 22,065). ‘Blue Chip’ is similar to ‘Podcept1’ in having a short plant height, a long bloom period, and reduced fertility. ‘Blue Chip’ differs from ‘Podcept1’ in having narrower and shorter inflorescences that lack indeterminate flowering and flowers that are single only and blue in color. ‘Podaras #9’ is similar to ‘Podcept1’ in having an early and long bloom period and a compact and upright plant habit. ‘Podaras #9’ differs from ‘Podcept1’ in having inflorescences that lack indeterminate flowering, lighter colored single only flowers, and foliage that is gray-green in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Buddleia. The photographs were taken of a 4 month-old plant as grown outdoors in a 21-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of the overall plant habit of ‘Podcept1’ in bloom.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘Podcept1’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Podcept1’.

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 Buddleia.
