Abstract

A new and distinct cultivar of Aechmea plant named ‘Blue Dream’, characterized by its relatively large plant habit with upright to outwardly arching growth habit; long linear leaves with pale yellow and green-colored longitudinal stripes; freely-flowering habit with inflorescences held upright on strong red purple-colored scapes; long branched inflorescences with dark violet blue-colored flowers, dark red and violet blue-colored flower bracts and red purple-colored scape bracts; long-lasting inflorescences and good container and interiorscape performance; and resistance to Helminthosporium Leaf Spot.

Description

Botanical designation: Aechmea dichlamydea var. trinitensis X Aechmea fendleri.

Cultivar denomination: ‘BLUE DREAM’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Aechmea plant, botanically known as Aechmea dichlamydea var. trinitensis X Aechmea fendleri and hereinafter referred to by the cultivar name ‘Blue Dream’.

The new Aechmea plant is a product of a planned breeding program conducted by the Inventor in Princeton, Florida. The objective of the breeding program was to create new Aechmea plants with unique foliage and inflorescence coloration and good postproduction longevity.

The new Aechmea plant is a naturally-occurring mutation of Aechmea dichlamydea var. trinitensis X Aechmea fendleri ‘Blue Tango’, disclosed in U.S. Plant Pat. No. 11,743. The new Aechmea plant was discovered and selected by the Inventor as an offset of a single flowering plant from within a population of plants of ‘Blue Tango’ in Princeton, Florida in 2013.

Asexual reproduction of the new Aechmea plant by offsets in a controlled greenhouse environment in Princeton, Florida since 2014 has shown that the unique features of this new Aechmea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Aechmea 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 ‘Blue Dream’. These characteristics in combination distinguish ‘Blue Dream’ as a new and distinct Aechmea plant:

• • 1. Relatively large plant habit with upright to outwardly arching growth habit.
  • 2. Long linear leaves with pale yellow and green-colored longitudinal stripes.
  • 3. Freely-flowering habit with inflorescences held upright on strong red purple-colored scapes.
  • 4. Long branched inflorescences with dark violet blue-colored flowers, dark red and violet blue-colored flower bracts and red purple-colored scape bracts.
  • 5. Long-lasting inflorescences and good container and interiorscape performance.
  • 6. Resistant to Helminthosporium Leaf Spot.

Plants of the new Aechmea differ primarily from plants of the mutation parent, ‘Blue Tango’ in leaf color as leaves of plants of the new Aechmea have pale yellow and green-colored longitudinal stripes whereas plants of ‘Blue Tango’ have solid green-colored leaves.

Plants of the new Aechmea can be compared to plants of Aechmea dichlamydea var. trinitensis X Aechmea fendleri ‘America’, disclosed in U.S. Plant Pat. No. 27,762. In side-by-side comparisons, plants of the new Aechmea and ‘America’ differ primarily in leaf color as leaves of plants of the new Aechmea have pale yellow and green-colored longitudinal stripes with pale yellow-colored margins whereas plants of ‘America’ have creamy white, light green and green variegated leaves with green-colored margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Aechmea 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 Aechmea plant.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Blue Dream’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘Blue Dream’.

DETAILED BOTANICAL DESCRIPTION
