USPP31284P2 - Pulmonaria plant named ‘Pretty in Pink’ - Google Patents

Abstract

A new and distinct hybrid of Lungwort plant named Pulmonaria ‘Pretty in Pink’ characterized by silver spotting on medium green foliage, medium pink flower buds on dense, upright, highly branched stems, that open and retain their bright rose-pink color on mostly outright to slightly drooping campanulate flowers. The new plants show excellent vigor and good mildew resistance.

Description

Botanical denomination: Pulmonaria hybrid.

Variety designation: ‘Pretty in Pink’.

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

The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2018. The claimed plant was first sold on Jul. 9, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Pulmonaria ‘Pretty in Pink’ 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 to 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 Pulmonaria and given the cultivar name of ‘Pretty in Pink’. Pulmonaria is in the family Boraginaceae. The new cultivar originated from a multiple generation crossing beginning with ‘Pink Haze’ U.S. Plant Pat. No. 14,307 selected in a private garden in Zeeland, Mich., USA in May of 2015.

The new plant was initially asexually propagated at the same nursery in the summer of 2016 by division of the rhizome and followed by plant tissue culture of the shoot tip. The result plants have shown themselves to be stable and true to type in successive generations of asexual propagation by division at the same nursery in Zeeland, Mich. and also through shoot tip tissue culture.

SUMMARY OF THE INVENTION

Compared with ‘Pink Haze’, the new plant has darker pink flower buds, the foliage is more ovate and less oblanceolate and the color is more yellow-green with dapped spots of lighter yellow-green. Compared with the male parent and female parents, the new cultivar has better pink flower color and the flower stems are more upright. The nearest comparison plants known to the inventor include: ‘Dora Bielefeld’ (not patented), and ‘Pierre's Pure Pink’ (not patented). ‘Pierre's Pure Pink’ has lighter pink flowers that are more cupped and not as flared, and the habit and foliage are smaller. ‘Dora Bielefeld’ has smaller and more cupped flowers and the foliage is pale green.

Pulmonaria ‘Pretty in Pink’ is distinct from all other lungwort plants known to the inventor by the following combined traits:

• • 1. Medium pink flower buds on upright highly-branched stems in mid-spring;
  • 2. Pink flower buds open to consistently bright, rose-pink, campanulate flowers on numerous dense panicles;
  • 3. Medium green foliage with prominent silver spotting on both cauline leaves and basal leaves arising after flowering;
  • 4. Excellent vigor producing compact mounded habit; and
  • 5. Foliage shows good mildew resistance.

BRIEF DESCRIPTION OF THE DRAWING

The photographs of the new plant 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 photographs are of a three-year-old plant growing in a partially shaded garden in Zeeland, Mich.
