USPP22733P3 - Gloriosa plant named ‘Crimson Flame’ - Google Patents

Abstract

A new and distinct Gloriosa cultivar named ‘Crimson Flame’ is disclosed, characterized by large flowers with an open petal habit, rapid growth, and exceptional longevity of flowers on the plant. Flowers are characteristically more red than known Gloriosa varieties. The new cultivar is a Gloriosa, typically suited indoor ornamental container use.

Description

Latin name of the genus and species: Gloriosa hybrid.

Variety denomination: ‘Crimson Flame’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the seed parent, an unpatented Gloriosa superba with the pollen parent, an unpatented proprietary selection of Gloriosa lutea referred to as ‘#7’ directed by the inventor in 1998. The crossing was made in Nootdorp, the Netherlands, at a commercial greenhouse owned by the breeder.

‘Crimson Flame’ was discovered by the inventor, Wim Brouwer, in 1999 in Nootdorp, the Netherlands, at the same commercial greenhouse among seedlings resulting from the 1998 crossing.

Asexual reproduction of the new cultivar ‘Crimson Flame’ was first performed in the Netherlands at the inventor's greenhouse by tubers, and subsequently by tissue culture at a laboratory in the Netherlands. ‘Crimson Flame’ has since produced multiple generations from tubers and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Crimson Flame’ 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 ‘Crimson Flame.’ These characteristics in combination distinguish ‘Crimson Flame’ as a new and distinct Gloriosa cultivar:

• • 1. Larger flower, with a more open petal habit.
  • 2. More rapidly growing plant.
  • 3. Flower color with significantly more red.
  • 4. Exceptionally long flower longevity on the plant

PARENTAL COMPARISON

Plants of the new cultivar ‘Crimson Flame’ are similar to the female parent Gloriosa superba in most horticultural characteristics. However, ‘Crimson Flame’ differs in producing faster growing plants, with shorter internodes, and larger, darker leaves. ‘Crimson Flame’ also has significantly more red in the flower color, and a flower with a more open petal habit.

Plants of the new cultivar ‘Crimson Flame’ are similar to the male parent Gloriosa lutea ‘#7’ in most horticultural characteristics. However, ‘Crimson Flame’ differs in producing more flowers per flowering stem, flowers and flowers with more longevity than the male parent.

COMMERCIAL COMPARISON

‘Crimson Flame’ can best be compared to the parent varieties.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘Crimson Flame’ grown in a greenhouse in Nootdorp, the Netherlands. These plants are approximately 6 months old, shown in a 18 and 15 cm pots. The photograph was 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.
