plant named ‘Flo’

Abstract

A new and distinct cultivar of Guzmania plant named ‘Flo’, characterized by its upright and outwardly arching growth habit; narrow dark green-colored leaves; large inflorescences with showy dark red-colored bracts; and good postproduction longevity.

Description

Botanical designation: Guzmania cardinalis×Guzmania wittmackii.

Cultivar denomination: ‘FLO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Guzmania plant, botanically known as Guzmania cardinalis×Guzmania wittmackii and hereinafter referred to by the name ‘Flo’.

The new Guzmania plant is a product of a planned breeding program conducted by the Inventors in Laarne, Belgium. The objective of the breeding program is to create new Guzmania plants having unique bract colors and enhanced postproduction longevity.

The new Guzmania originated from a cross-pollination made by the Inventors in January, 2009 in Laarne, Belgium of an unnamed proprietary selection of Guzmania cardinalis, not patented, as the female, or seed, parent with an unnamed proprietary selection of Guzmania wittmackii, not patented, as the male, or pollen, parent. The new Guzmania plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Laarne, Belgium in January, 2011.

Asexual reproduction of the new Guzmania plant by tissue culture in a controlled environment in Laarne, Belgium since June, 2012 has shown that the unique features of this new Guzmania plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Guzmania have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘Flo’. These characteristics in combination distinguish ‘Flo’ as a new and distinct Guzmania plant:

• • 1. Upright and outwardly arching growth habit.
  • 2. Narrow dark green-colored leaves.
  • 3. Large inflorescences with showy dark red-colored bracts.
  • 4. Good postproduction longevity.

Plants of the new Guzmania can be compared to plants of the female parent selection. Plants of the new Guzmania differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Guzmania are taller and more vigorous than plants of the female parent selection.
  • 2. Plants of the new Guzmania have darker red-colored bracts than plants of the female parent selection.

Plants of the new Guzmania can be compared to plants of the male parent selection. Plants of the new Guzmania differ primarily from plants of the male parent selection in bract color as plants of the male parent selection have orange-colored bracts.

Plants of the new Guzmania can be compared to plants of Guzmania ‘Indian Night’, not patented. In side-by-side comparisons conducted in Laarne, Belgium, plants of the new Guzmania and ‘Indian Night’ differed in the following characteristics:

• • 1. Plants of the new Guzmania and ‘Indian Night’ differed in bract color as plants of ‘Indian Night’ had purple-colored bracts.
  • 2. Bracts of plants of the new Guzmania were strongly curved whereas bracts of plants of ‘Indian Night’ were moderately curved.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Guzmania plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Guzmania plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Flo’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Flo’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 13-cm containers in a glass-covered greenhouse in Laarne, Belgium and under cultural practices typical of commercial Guzmania production. During the production of the plants, day temperatures ranged from 21° C. to 30° C., night temperatures ranged from 20° C. to 21° C. and maximum light levels were 18,000 lux. Plants were three years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
