USPP36083P2 - Baptisia plant named ‘Grape Escape’ - Google Patents

Abstract

A new and distinct plant cultivar of hardy herbaceous False Indigo plant named Baptisia ‘Grape Escape’ is characterized by flowers that open up deep purplish-red with a light cream-colored keel beginning in late May and continuing for three weeks. The new plant has a narrow, medium height, upright, vase-shaped, multi-stemmed, winter-hardy habit with glaucous dark-green tri-foliate foliage and is suitable for landscaping as a specimen or en masse.

Description

Botanical classification: Baptisia hybrid.

Cultivar designation: ‘Grape Escape’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

Baptisia ‘Grape Escape’ was first promoted with a brief description and photographs on a website operated by Walters Gardens, Inc. on Feb. 1, 2023, followed by the “Walters Gardens 23-24 Catalog” initially distributed by Walters Gardens, Inc. on May 19, 2023. The first private sale of Baptisia ‘Grape Escape’ was made by Walters Gardens, Inc. on Jan. 23, 2023, to Edwards Greenhouse and Flowershop. Information and plants for this sale and all sales thereafter were obtained from the inventor. No plants of Baptisia ‘Grape Escape’ have been sold or offered for sale, 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.

BACKGROUND OF THE INVENTION

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

‘Grape Escape’ arose from an ongoing breeding program of the inventor at a wholesale perennial nursery in Zeeland, Michigan 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 ‘Grape Escape’ was a single seedling selection from a cross between a ‘Pink Truffles’ U.S. Plant Pat. No. 26,588 as the female or seed parent times ‘Blue Towers’ U.S. Plant Pat. No. 27,088 as the male or pollen parent. The cross was performed at the same nursery in Zeeland, Michigan with the seeds collected on Jul. 15, 2015. The seeds were then sown at the same nursery in Zeeland, Michigan in the spring of 2016. The initial selection was made in the spring of 2017 at the same nursery in Zeeland and later given the breeder code 15-12-2.

‘Grape Escape’ was initially asexually propagated by stem cuttings at a wholesale perennial nursery in Zeeland, Michigan in 2018. 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, ‘Violet Dusk’ U.S. Plant Pat. No. 32,553, ‘Burgundy Blast’ U.S. Plant Pat. No. 34,689, and ‘Plum Rosy’ (not patented).

‘Grape Taffy’ is shorter and more compact in habit with fewer flowers that are a lighter reddish-purple with a buff-yellow keel. ‘Violet Dusk’ is a similar habit with shorter inflorescences and the flowers are lavender-violet with cream-colored keels. ‘Burgundy Blast’ has a slightly smaller habit with shorter inflorescences and the flowers are deep wine red without the contrasting ream-colored keel. ‘Plum Rosy’ has a smaller habit and flowers that open mauve pink and turn to a near white with age.

The female parent has clear soft-pink flowers on a slightly taller plant. The male parent has a taller habit, and the flowers are dark purplish-blue.

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

• • 1. Flowers open deep purplish-red with a light creamy-colored keel and retain their color through the effective season;
  • 2. Flowering begins in late May in Michigan and continues for about three weeks;
  • 3. Medium-height, upright, vase-shaped, multi-stemmed, winter-hardy habit;
  • 4. Glaucous, dark-green, tri-foliate foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of ‘Grape Escape’ demonstrate the unique traits and the overall appearance of the new plant. The colors are as accurate as reasonably possible with color reproductions. Variations in ambient light spectrum, source, and direction may cause the appearance of minor variation in color.
