Botanical classification: Baptisia hybrid.

Cultivar designation: ‘Burgundy Blast’.


Baptisia ‘Burgundy Blast’ was promoted in a non-enabling descriptions and photographs on a website operated by Walters Gardens, Inc. on Feb. 1, 2021, followed by the “Walters Gardens 21-22 Catalog” initially distributed by Walters Gardens, Inc. on May 21, 2021. The first enabling disclosure of Baptisia ‘Burgundy Blast’, in the form of a sale, was made by Walters Gardens, Inc. on May 17, 2021 to Phoenix Perennials, Monrovia Nursery, Wildflower Farms and Renegade Acres. Information and plants for this sale and all sales thereafter were obtained from the inventor. No plants of Baptisia ‘Burgundy Blast’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.


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

‘Burgundy Blast’ arose from an ongoing breeding program of the inventor at a wholesale perennial nursery in Zeeland, Mich. with the specific intention of improving garden worthiness of perennial false indigo plants with a wider variety of flower colors and improved garden habit.

Baptisia ‘Burgundy Blast’ was a single seedling selection from a cross between a proprietary unnamed, unreleased hybrid selection of Baptisia minor (not patented) as the female or seed parent times a proprietary unnamed, unreleased hybrid selection of Baptisia alba (not patented) as the male or pollen parent. The cross was performed at the same nursery in Zeeland, Mich. with the seeds collected on Aug. 23, 2011. The seeds were then sown the same nursery in Zeeland, Mich. on Oct. 6, 2011. The initial selection made in the spring of 2013 at the same nursery in Zeeland and later given the breeder code 11-11-11.

‘Burgundy Blast’ was initially asexually propagated by stem cuttings at a wholesale perennial nursery in Zeeland, Mich. in 2015. The resultant plants have demonstrated that the new plant has remained stable and true to type in successive generations of asexual propagation.

The nearest comparison plants known to the inventor are: ‘Grape Taffy’ U.S. Plant Pat. No. 26,587, ‘Pink Truffles’ U.S. Plant Pat. No. 26,588, ‘Violet Dusk’ U.S. Plant Pat. No. 32,553, ‘Lavender Stardust’ (not patented) and ‘Plum Rosy’ U.S. Plant patent application Ser. No. 17/300,370.

‘Grape Taffy’ is much shorter and more compact in habit and the flowers are reddish-purple with a buff-yellow keel. ‘Pink Truffles’ is taller and broader in habit with soft pink flowers having a yellow keel. ‘Violet Dusk’ is slightly taller in height and width and the flowers are lavender-violet with cream-colored keels. ‘Lavender Stardust’ has a taller vase-shaped habit, but the flowers have a pale-yellow keel with the lilac-purple banner, and the inflorescence is much longer. ‘Plum Rosy’ has a slightly larger habit and flowers that open a soft-yellow and turn to a dusty raspberry-purple.

Compared with plants of Baptisia minor known to the Inventor, the new plant is taller in habit and has a longer inflorescence. Typical Baptisia alba typically has white flowers. The female parent has blue flowers on a more compact plant and the inflorescence is longer. The male parent has a similar habit, but the flowers are pure white, later opening, the inflorescences are longer and the peduncles are light green.

The new plant differs from all Baptisia known to the inventor in the following combined traits:

    • 1. Flowers open dark wine-purple and retain their color through the effective season;
    • 2. Flowering begins late-May in Michigan and continues for about two weeks;
    • 3. Narrow, medium-height, upright, vase-shaped, multi-stemmed, winter-hardy habit;
    • 4. Glaucous, dark-green, tri-foliate foliage.


The photographs of ‘Burgundy Blast’ demonstrate the unique traits of the new plant and the overall appearance. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color. The accompanying photograph is of a six-year-old plant growing in an open full-sun trial garden in Zeeland, Mich.
