| Abstract: |
A new and distinct cultivar of Pulmonaria plant characterized by lime green blotches and spots over contrasting deep green foliage and purple pink flowers changing to deep violet blue, and with mildew resistance. |
| Claim: |
I claim:
1. A new and distinct cultivar of Pulmonaria plant as shown and described. |
| Description: |
Botanical classification: Pulmonaria hybrid.
Variety denomination: `Irish Spring`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of a hardy perennial of the genus Pulmonaria, and known by the cultivar name `Irish Spring`. The genus Pulmonaria is a member of the family Boraginaceae.
The new cultivar originated as an open-pollinated cross between unknown parents in a field of selected hybrid Pulmonaria. This is known to be an outcross because Pulmonaria does not normally self-pollinate. Due to the fact that the instantplant and parent plants are interspecific hybrids from several generations of interbreeding and selecting, no species designations are given.
This plant is characterized by the following: 1. Deep green foliage with a lime green overlay to the margin or blotched on the surface. 2. Deep pink flowers changing to deep violet blue. 3. Mildew resistance.
This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by tissue culture using standard micropropagationtechniques with terminal and lateral shoots as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not beenevaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

The lime green "silvering" or blotches is a color not in The R.H.S. chart between their Greyed Green 193B and Yellow Green 148B. Bottom -- Yellow Green 146C. Cauline leaves (found in the spring only on the flowering stems):Type.--Simple. Arrangement.--Alternate. Shape.--Oblanceolate to ovate. Length.--8 cm. Width.--2.5 cm. Margins.--Undulate and ciliate. Apex.--Acuminate. Base.--Clasping, sessile. Leaf texture.--Hirsute. Venation.--Pinnate.

Flower bud: Size.--1.6 cm. long and 0.4 cm. wide. Shape.--Ovoid on a tube, with 0.55 cm of corolla showing. Color.--Red. Red Group 51A withdarker areas of Red Purple 63A. Flower: Type.--Actinomorphic. Shape.--Funnelform. Size.--2 cm. deep and 2 cm. wide. Corolla.--5 fused petals with rounded lobes. Color.--Changes with maturity. Newly opened flowers are light rose red, Red 51B. They change to blue rose, Red Purple 63C with a Violet Blue 90A overlay on the lobes. Mature flowers are a deep violet blue, Violet Blue 94A.

Disease: Mildew resistant, the main problem for Pulmonaria. No mildewobserved on plants grown under commercial conditions in Canby, Oreg.
COMPARISONS TO SIMILAR PULMONARIA
Compared to Pulmonaria `Emerald Isles` (U.S. Plant Pat. No. 12,339), the instant plant also has light green spots and blotches, but Pulmonaria `Irish Spring` has lighter spots and blotches and a lower, flatter habit of growth. The new cultivaralso has larger flowers with a darker blue violet color. The cauline leaves of Pulmonaria `Emerald Isles` are rounder and shorter.
