Botanical classification: Baptisia hybrid.
Cultivar designation: ‘Vanilla Cream’.
The present invention relates to a new and distinct cultivar of Baptisia plant of hybrid origin, botanically known as Baptisia ‘Vanilla Cream’ and will be referred to hereafter by its cultivar name, ‘Vanilla Cream’. The new cultivar represents a new false indigo, an herbaceous perennial grown for landscape use.
The new Invention arose from an ongoing controlled breeding program in Waseca, Minn. that was established by the Inventor in 1998 using superior selections of numerous species of Baptisia with the goal of developing unique color forms and plant habits of Baptisia suited for general garden and landscape use.
‘Vanilla Cream’ was derived from seed collected after open pollination of many unnamed plants of different species of Baptisia in a trial bed in 1998. ‘Vanilla Cream’ was selected in 2007 as a single plant amongst the resulting seedlings. Based on the characteristics of the new cultivar, the parent plants are believed to be Baptisia cinera and Baptisia alba.
Asexual propagation of the new cultivar was first accomplished by stem cuttings in 2008 in Zeeland, Mich. under the direction of the Inventor. 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 ‘Vanilla Cream’ as a unique cultivar of Baptisia.
- 1. ‘Vanilla Cream’ exhibits flowers that are creamy white in color.
- 2. ‘Vanilla Cream’ exhibits blue-green foliage.
- 3. ‘Vanilla Cream’ exhibits new growth tips that are brown-purple in color.
- 4. ‘Vanilla Cream’ exhibits a compact, mounded growth habit.
- 5. ‘Vanilla Cream’ is hardy in U.S.D.A. Zones 4 to 8.
‘Vanilla Cream’ differs from the parent plant Baptisia cinera in having flowers that are creamy white in color rather than yellow. In addition, the inflorescences of ‘Vanilla Cream’ are significantly longer and held upright compared to the shorter flower spikes of B. cinera, which are held at a 45° angle. ‘Vanilla Cream’ can also be compared to B. albescens and B. alba. ‘Vanilla Cream’ is similar to both in flowering habit, but differs by having a more compact growth habit and a more mounding form rather than the vase-shaped growth habit of B. alba and B. albescens. ‘Vanilla Cream’ can also be compared to B. leucophaea. ‘Vanilla Cream’ differs from B. leucophaea in having upright inflorescence rather than horizontal, a larger growth habit, leaves that are not pubescent, and having flowers that are whiter in color.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Baptisia. The photographs were taken of a plant about seven years in age as grown outdoors in a garden in Zeeland, Mich.

The 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 Baptisia.
The following is a detailed description of 5 year-old plants of the new cultivar as grown outdoors in a trial plot in Waseca, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
