USPP35154P2 - Pulmonaria plant named ‘TNPULRASFRO’ - Google Patents

Abstract

A new and distinct Pulmonaria plant characterized by leaves having a unique combination of white margins with a frosted, mottled appearance and dark raspberry colored flowers.

Description

Botanical classification: Pulmonaria spp.

Varietal denomination: ‘TNPULRASFRO’.

Commercial trade name: “Raspberry Frost”.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct Pulmonaria plant, of the family Boraginaceae, having the varietal name ‘TNPULRASFRO’. The new variety originated as a tissue culture mutation of a Pulmonaria plant named ‘Raspberry Splash’ (U.S. Plant Pat. No. 12,138). The new variety was discovered as a spontaneous mutation in a batch of tissue culture plants in Canby, Oreg.

When compared to its parent, Pulmonaria plant named ‘Raspberry Splash’, the new variety has a smaller, more compact habit and exhibits cream variegation in an irregular fashion on the leaves. When compared to Pulmonaria rubra plant named ‘David Ward’ (unpatented), the new variety has narrower leaves of a gray-green color rather than yellow-green, more mottling on the leaves, and coral rather than dark raspberry colored flowers.

The new variety has only been reproduced by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture performed in Canby, Oreg. shows that the characteristics and distinctions described herein come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

When compared to other Pulmonaria plants known to the breeder, the new variety is characterized by the following:

• • 1. Irregularly margined, white-edged variegation on lanceolate leaves;
  • 2. Gray-green mottled leaves with silvery overlay covering 90 percent of the leaf area; and
  • 3. High vigor.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety at approximately 1 year of age, with the colors being as nearly true as possible with color illustrations of this type:

FIG. 1 illustrates a close-up of view of the leaves and flowers of the new variety in Canby, Oreg. in April; and

FIG. 2 illustrates an original plant in a trial field in Canby, Oreg. in June.
