Abstract

A new cultivar of interspecific Baptisia, ‘Mojito’, that is characterized by its flowers that are light yellow-green in color, its flowers that are borne very densely on the raceme, its inflorescences that are borne upright and within the foliage, its foliage that is deep yellow-green in color, its stems that do not lodge, and its early and extended four-week long bloom period that begins in early May in northern Illinois.

Description

Botanical classification: Baptisia hybrid.

Cultivar designation: ‘Mojito’.

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

The new invention arose from an ongoing breeding program in a dedicated test plot in Glencoe, Ill. The objective of the breeding program is to develop novel interspecific hybrids of Baptisia that exhibit unique flower coloration, hybrid vigor, ease of clonal propagation, and desirable plant habits.

‘Mojito’ was selected as a single unique plant by the Inventor in June of 2008 after evaluating seedlings that derived from a cross made in May of 2004 between unnamed plants of hybrid Baptisia from the Inventor's breeding program. The female parent was a seedling that derived from open pollination of an interspecific hybrid Baptisia (australis×leucophaea). The male parent was a seedling that derived from open pollination of an interspecific hybrid Baptisia (australis×sphaerocarpa).

Asexual propagation of the new cultivar was first accomplished by stem tip cuttings under the direction of the Inventor in July of 2009 in Glencoe, Ill. Asexual propagation by stem 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. These attributes in combination distinguish ‘Mojito’ as a unique cultivar of Baptisia.

- 1. ‘Mojito’ exhibits flowers that are light yellow-green in color.
- 2. ‘Mojito’ exhibits flowers that are borne very densely on the raceme.
- 3. ‘Mojito’ exhibits inflorescences that are borne upright and within the foliage.
- 4. ‘Mojito’ exhibits foliage that is deep yellow-green in color.
- 5. ‘Mojito’ exhibits stems that do not lodge.
- 6. ‘Mojito’ exhibits an early and extended four-week long bloom period that begins in early May in northern Illinois.

The female parent of ‘Mojito’ differs from ‘Mojito’ in having flowers that are cream colored with a hint of yellow, in having flowering stems that are held clear above the foliage, and in having stems the occasionally lodge. The male parent differs from ‘Mojito’ in having flowers that are cream colored with a hint of butter yellow, in having a conspicuously backswept banner petal, and in having a bloom period that begins two weeks later. ‘Mojito’ can be most closely compared to the Baptisia cultivar ‘Starlite’ (U.S. Plant Pat. No. 19,971) and typical plants of Baptisia bracteata (syn. B. leucophaea). ‘Starlite’ is similar to ‘Mojito’ in having an early bloom period starting in early May in northern Illinois and in being very floriferous. ‘Starlite’ differs from ‘Mojito’ in having flowers that are lavender to blue in color with a yellow keel, in having inflorescences that are upright to leaning in aspect, and in having flowers that are borne less densely on the raceme. Typical plants of Baptisia bracteata are similar to ‘Mojito’ in having an early bloom period starting in early May in northern Illinois. Typical plants of Baptisia bracteata differ from ‘Mojito’ in having flowers that are cream colored with hints of lemon yellow, in having conspicuously pubescent stems and foliage, in having horizontal inflorescences, in having flowers that are produced on only one side of the inflorescences.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Baptisia. The photographs in FIG. 1 and FIG. 2 were taken of a plant five years in age and the photograph in FIG. 3 was taken of a plant nine years in age, both plants were grown outdoors in a trial plot in Glencoe, Ill.

The photograph in FIG. 1 provides a close-up view of an inflorescence of ‘Mojito’.

The photograph in FIG. 2 provides a side view of ‘Mojito’ in bloom and illustrates the plant habit and flowering habit.

The photograph in FIG. 3 provides a side view of the late summer foliage of ‘Mojito’.

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.
