Abstract

A new and distinct cultivar of Buddleia plant named ‘PIIBD-II’, characterized by its compact, rounded to upright growth habit, dark green foliage, reddish pink flowers with an orange center, and long flowering season, with flowers produced from summer to the first frost.

Description

Genus and species of plant claimed: Buddleia hybrid Franch.

Variety denomination: ‘PIIBD-II’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleia plant, botanically known as Buddleia hybrid Franch., commonly known as butterfly-bush, and hereinafter referred to by the cultivar name ‘PIIBD-II’. ‘PIIBD-II’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

‘PIIBD-II’ originated from an open-pollination of the cultivar ‘Miss Ruby’ (U.S. Plant Pat. No. 19,950) growing in Watkinsville, Ga. in 2010. The cultivar ‘PIIBD-II’ originated and was selected in a cultivated environment in Watkinsville, Ga. from the progeny of this open-pollination by continued evaluation for growth habit, foliage and flower characteristics.

Asexual reproduction of ‘PIIBD-II’ by stem cuttings in Watkinsville, Ga. since 2011 has shown that all the unique features of this new Buddleia, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘PIIBD-II’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been observed and represent the characteristics of the new cultivar. In combination these characteristics distinguish ‘PIIBD-II’ from all other varieties in commerce known to the inventor.

• • 1. Compact, rounded to upright growth habit;
  • 2. Dark green foliage;
  • 3. Reddish pink flowers with an orange center;
  • 4. Long flowering season, with flowers produced from summer to the first frost.

‘PIIBD-II’ is distinguished from its female parent, ‘Miss Ruby’, by its flower color and inflorescence size. ‘PIIBD-II’ has darker reddish pink flower color and larger inflorescences, whereas ‘Miss Ruby’ has lighter medium pink flower color and smaller inflorescences.

‘PIIBD-II’ can be compared to ‘Miss Molly’ (U.S. Plant Pat. No. 23,425), but differs in the following characteristics. ‘PIIBD-II’ has larger foliage, darker reddish pink flower color and larger inflorescences, whereas ‘Miss Molly’ has smaller foliage, lighter reddish purple flower color and smaller inflorescences.

‘PIIBD-II’ can also be compared to its sister plant ‘PIIBD-III’ (Pending Plant patent Ser. No. 13/998,398). ‘PIIBD-II’ has reddish pink flowers with an orange center and dark green foliage, whereas ‘PIIBD-III’ has violet flowers with an orange center and grey-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Buddleia.
