Abstract

A new cultivar of interspecific Baptisia, ‘Blonde Bombshell’, that is characterized by its flowers that are light yellow in color, its compact and upright and slightly mounded plant habit, its flower stems that are held well above the foliage with short internode lengths between flowers, and its heavy blooming habit with numerous flowering stems and numerous flowers per flowering stem.

Description

Botanical classification: Baptisia hybrid.

Cultivar designation: ‘Blonde Bombshell’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of hybrid Baptisia plant, botanically known as Baptisia ‘Blonde Bombshell’ and will be referred to hereafter by its cultivar name, ‘Blonde Bombshell’. The new cultivar represents a new false indigo, an herbaceous perennial grown for landscape use.

The new invention arose from an ongoing breeding program by the Inventor in Raleigh, N.C. The objective of the breeding program is to develop novel interspecific hybrids of Baptisia that exhibit good garden performance with tall and upright plant habits and inflorescences that are held well above the foliage.

‘Blonde Bombshell’ originated as a seedling that arose from seed planted from open pollination of an unnamed plant of Baptisia shaerocarpa in April of 2008 in a controlled block of potential pod and seed parents. The male parent is therefore unknown. The new Baptisia was selected as a single unique plant in 2008.

Asexual propagation of the new cultivar was first accomplished by shoot tip cuttings in May of 2009 in Raleigh, N.C. under the direction of the Inventor. Asexual propagation by shoot tip 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 as observed in Raleigh, N.C. These attributes in combination distinguish ‘Blonde Bombshell’ as a unique cultivar of Baptisia.

- 1. ‘Blonde Bombshell’ exhibits flowers that are light yellow in color.
- 2. ‘Blonde Bombshell’ exhibits a compact and upright and slightly mounded plant habit.
- 3. ‘Blonde Bombshell’ exhibits flower stems that are held well above the foliage with short internode lengths between flowers.
- 4. ‘Blonde Bombshell’ exhibits a heavy blooming habit with numerous flowering stems and numerous flowers per flowering stem.

The female parent of ‘Blonde Bombshell’ differs from ‘Blonde Bombshell’ in having flowers that are darker yellow in color, fewer flowering stems that are shorter in height with less flowers and greater internode lengths between flowers, and in having a less upright plant habit. ‘Blonde Bombshell’ can be most closely compared to Baptisia cultivars ‘Lemon Meringue’ (U.S. Plant Pat. No. 24,280) and ‘Anne’ (not patented). ‘Lemon Meringue’ is similar to ‘Blonde Bombshell’ in having yellow flowers and upright flowering stems. ‘Lemon Meringue’ differs from ‘Blonde Bombshell’ in having flowering stems that are darker in color with longer internodes between flowers, in having a much wider plant habit, and in blooming 1 to 2 weeks later. ‘Anne’ is similar to ‘Blonde Bombshell’ in flower color and season of bloom. ‘Anne’ differs from ‘Blonde Bombshell’ in having flowering stems that are darker in color with longer internodes between flowers, in having a much wider plant habit, and in blooming slightly later.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Baptisia. The photographs were taken of plants four years in age as grown outdoors in a trial garden in Raleigh, N.C.

The photograph in FIG. 1 provides a side view of ‘Blonde Bombshell’ in bloom and illustrates its plant habit and prolific blooming habit.

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

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 Baptisia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of seven year-old plants of the new cultivar as grown outdoors in a trial garden in Raleigh, N.C.

The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
