Abstract

A new and distinct Guzmania cultivar named ‘Brimstone’ is disclosed, characterized by a compact plant habit, and unique bright red bracts.

Description

Latin name of the genus and species: Guzmania hybrid.

Variety denomination: ‘Brimstone’.

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, of Guzmania hybrid ‘Cutucu Hybrid,’ unpatented with the unnamed pollen parent Guzmania wittmackii×variegata, unpatented, directed and performed by the inventor in February 1999. The cross was made at a commercial greenhouse in Vista, Calif.

‘Brimstone’ was discovered by the inventor, Jeffrey Kent, in December of 2002 at a commercial greenhouse in Vista, Calif. in a group of seedlings resulting from the 1999 crossing.

Asexual reproduction of the new cultivar ‘Brimstone’ was first performed at a commercial laboratory in Vista, Calif. by tissue culture in 2003. Since that time, approximately 6 generations have been reproduced by micro-propagation and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Brimstone’ 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 ‘Brimstone’ These characteristics in combination distinguish ‘Brimstone’ as a new and distinct Guzmania cultivar:

- 1. Very clear, bright inflorescence color.
- 2. Extension of bright color from inflorescence through scape.
- 3. Rapid growth.
- 4. Foliage tips remain healthy and intact, not showing the condition commercially known as “leaf tipping” typical of Guzmanias.

PARENTAL COMPARISON

Plants of the new cultivar ‘Brimstone’ are similar to the seed parent in most horticultural characteristics. However, ‘Brimstone’ differs from Guzmania hybrid ‘Cutucu Hybrid’ in having a brighter inflorescence color, taller plant height and much faster growth.

Plants of the new cultivar ‘Brimstone’ are similar to the pollen parent in most horticultural characteristics. However, ‘Brimstone’ differs from the unnamed Guzmania wittmackii×variegata in having a brighter inflorescence color, more compact plant habit, and much faster growth.

COMMERCIAL COMPARISON

‘Brimstone’ can be compared to the patented commercial variety Guzmania ‘Deplakar’, U.S. Plant Pat. No. 13,754. Plants of ‘Deplakar’ are similar to plants of ‘Brimstone’ in most horticultural characteristics, however, ‘Brimstone’ has shorter, narrow foliage, scape and terminal bracts more yellow than orange-yellow in color.

‘Brimstone’ can be compared to the unpatented commercial variety Guzmania ‘Marjan’ Plants of ‘Marjan’ are similar to plants of ‘Brimstone’ in most horticultural characteristics, however, ‘Brimstone’ has a wider inflorescence, and a shorter overall plant height than ‘Marjan’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Brimstone’ grown in a greenhouse in Florida. This plant is approximately 2 years old, shown in a 6 inch pot. 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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Brimstone’ plants grown in a climate controlled greenhouse in Miami, Fla. Temperatures ranged from 20° C. to 28° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
