BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agave plant, botanically known as Agave tuberosa (formerly referred to as Polianthes tuberosa) and hereinafter referred to by the name ‘NCYU Cherry’.

The new Agave plant is a product of a planned breeding program conducted by the Inventor in Chiayi City, Taiwan. The objective of the breeding program is to create relatively compact and upright Agave plants with attractive inflorescences.

The new Agave plant originated from a cross-pollination in July, 2011 in Chiayl City, Taiwan of a proprietary selection of Agave tuberosa identified as code number 59 #, not patented, as the female, or seed, parent with a proprietary selection of Agave tuberosa identified as code number 84E19, not patented, as the male, or pollen, parent. The new Agave plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Chiayi City, Taiwan in November, 2011.

Asexual reproduction of the new Agave plant by divisions in a controlled environment in Puli, Taiwan since March, 2015 has shown that the unique features of this new Agave plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Agave 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 ‘NCYU Cherry’. These characteristics in combination distinguish ‘NCYU Cherry’ as a new and distinct Agave plant:

• • 1. Upright plant habit.
  • 2. Straight lanceolate-shaped leaves that are not twisting.
  • 3. Numerous semi-double to double-type purplish red-colored flowers arranged on upright and strong flower scapes.
  • 4. Pleasant fragrance.
  • 5. Good cut flower performance.

Plants of the new Agave differ primarily from plants of the female parent selection in flower size as plants of the new Agave have larger flowers than plants of the female parent selection. In addition, plants of the new Agave are slightly taller than plants of the female parent selection.

Plants of the new Agave differ primarily from plants of the male parent selection in flower size as plants of the new Agave have smaller flowers than plants of the male parent selection. In addition, plants of the new Agave are taller than plants of the male parent selection.

Plants of the new Agave can be compared to plants of Polianthes hybrida ‘Chia Nong Pink Sapphire’, disclosed in U.S. Plant Pat. No. 26,460. In side-by-side comparisons, plants of the new Agave and ‘Chia Nong Pink Sapphire’ differ in the following characteristics:

• • 1. Plants of the new Agave are shorter than plants of ‘Chia Nong Pink Sapphire’.
  • 2. Plants of the new Agave have smaller flowers than plants of ‘Chia Nong Pink Sapphire’.
  • 3. Plants of the new Agave and ‘Chia Nong Pink Sapphire’ differ in flower color as plants of the new Agave have purplish red-colored flowers whereas plants of ‘Chia Nong Pink Sapphire’ have light lilac pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

The photograph is a top perspective view of typical flowering plants of ‘NCYU Cherry’ grown in a ground bed.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the late summer in ground beds in a glass-covered greenhouse in Lisse, The Netherlands and under cultural practices typical of commercial Agave production. During the production of the plants, day temperatures ranged from 20° C. to 27° C. and night temperatures ranged from 15° C. to 18° C. Plants were four months old when the photograph and description were taken.
