Abstract

A new and distinct Digitalis cultivar named ‘Firebird’ is disclosed, characterized by plants exhibiting improved Winter hardiness and basal branching without pinching. Plants are taller than known varieties and have a unique flower color combining greyed oranges and reds. The new variety is a Digitalis hybrida, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Digitalis x valinii.

Variety denomination: ‘Firebird’.

BACKGROUND OF THE INVENTION

The new Digitalis cultivar is a product of a planned breeding program by the inventor, John Fielding. The crossing resulting in this new variety was performed in 2010.

The seed parent variety is an unnamed, unpatented proprietary variety of Digitalis purpurea. The pollen parent is an unnamed, unpatented proprietary variety of Digitalis canariensis. The new variety was identified as a potentially interesting selection during June of 2015 at a private garden in London, United Kingdom. First public exposure was May 21, 2019, in the United Kingdom. Information and access to the new variety was initiated directly by the inventors or one who obtained the claimed invention directly or indirectly from the inventors. All public disclosures made between May 21, 2019 and the filing of this application fall within the exception allowed under 102(b)(1).

Asexual reproduction of the new cultivar Digitalis ‘Firebird’ was first performed during Summer of 2015, in London, United Kingdom, at the inventor's private garden using terminal vegetative cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar Digitalis ‘Firebird’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Firebird’. These characteristics in combination distinguish ‘Firebird’ as a new and distinct Digitalis cultivar:

    • 1. Improved winter hardiness.
    • 2. Produces branches from the base of the flower stem without pinching.
    • 3. Taller than known varieties.
    • 4. Interesting flower color combining greyed reds and oranges.
PARENT COMPARISONS

Plants of the new cultivar ‘Firebird’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘Firebird’ differ in the following:

    • 1. The new variety has a more branched habit than the seed parent.
    • 2. The new variety is more reliably perennial, while the seed parent often dies after flowering.
    • 3. The new variety flowers continuously, while the seed parent only flowers once per season.
    • 4. The new variety forms no viable seeds, while the seed parent produces plentiful viable seed.

Plants of the new cultivar ‘Firebird’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘Firebird’ differ in the following:

    • 1. The new variety is more cold-hardy than the pollen parent.
    • 2. The new variety has red flowers with orange throats, while the pollen parent has apricot-orange flowers.
    • 3. The new variety forms no viable seeds, while the pollen parent produces viable seed.
    • 4. The new variety flowers continuously, while the pollen parent flowers once or twice per year.
COMMERCIAL COMPARISONS

Plants of the new cultivar ‘Firebird’ can be compared to the commercial variety Digitalis valinii ‘TAKFORUGL’, U.S. Plant Pat. No. 25,640. These varieties are similar in most horticultural characteristics; however ‘Firebird’ differs in the following:

    • 1. Flowers of the new variety are red with orange throats, while this comparator's flowers are more red-purple.
    • 2. The new variety is a taller plant than this comparator.

Plants of the new cultivar ‘Firebird’ can also be compared to the commercial variety Digitalis valinii ‘TMDGFP001’, unpatented. These varieties are similar in most horticultural characteristics; however ‘Firebird’ differs in the following:

    • 1. Flowers of the new variety are red with orange throats, while this comparator's flowers are more pink.
    • 2. The new variety is a taller plant than this comparator.

Plants of the new cultivar ‘Firebird’ can also be compared to the commercial variety Digitalis ‘TMDG1301’, unpatented. These varieties are similar in most horticultural characteristics; however ‘Firebird’ differs in the following:

    • 1. Flowers of the new variety are red with orange throats, while this comparator's flowers are a paler pink.
    • 2. The new variety is a taller plant than this comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘Firebird’ grown outdoors in London, United Kingdom. Age of the plants photographed are approximately 26 weeks.

FIG. 2 illustrates in full color typical flowers of ‘Firebird’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
