plant named ‘Mardi Gras’

Abstract

A new and distinct Aeonium cultivar named ‘Mardi Gras’ is disclosed, characterized a unique, stable tricolor variegation, incorporating lemon yellow, green and burgundy. Plants are compact, and very suitable for production in smaller pot sizes, such as a commercial 4 inch nursery container. ‘Mardi Gras’ shows very little negative effects under low water stress, instead foliage makes a very attractive burgundy blush. The new variety is an Aeonium, typically produced as a garden or container plant.

Description

Latin name of the genus and species: Aeonium hybrid.

Variety denomination: ‘Mardi Gras’.

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 proprietary selection of Aeonium hybrid referred to as ‘#13’ with the pollen parent and unpatented commercial vareity, Aeonium hybrid ‘Velour.’ The crossing was made during March of 2007 in Vista, Calif., at a commercial greenhouse. ‘Mardi Gras’ was discovered by the inventor, Renee O'Connell, in October of 2007, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Mardi Gras’ was first performed in Vista, Calif., at a commercial greenhouse by vegetative leaf cuttings in October 2007. ‘Mardi Gras’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Mardi Gras’ 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 ‘Mardi Gras.’ These characteristics in combination distinguish ‘Mardi Gras’ as a new and distinct Aeonium cultivar:

• • 1. Unique tricolor variegated foliage.
  • 2. Unusual lemon yellow with green and pink blush foliage.
  • 3. Intense deep burgundy foliage color during times of drought or cold.

PARENTAL COMPARISON

Plants of the new cultivar ‘Mardi Gras’ are similar to the female parent ‘#13’ in most horticultural characteristics. However, ‘Mardi Gras’ differs in producing more compact plant, with tricolor foliage, whereas the seed parent does not have tri-color foliage, and has no lemon yellow coloration of its foliage.

Plants of the new cultivar ‘Mardi Gras’ are similar to the male parent ‘Velour’ in most horticultural characteristics. However, ‘Mardi Gras’ differs in having tricolor foliage, whereas the pollen parent does not have tri-color foliage, and has no lemon yellow coloration of its foliage.

COMMERCIAL COMPARISON

‘Mardi Gras’ can be compared to the unpatented commercial variety Aeonium arboreum ‘Tricolor.’ Plants of Aeonium arboreum ‘Tricolor’ are similar to plants of ‘Mardi Gras’ in most horticultural characteristics, however, ‘Mardi Gras’ produces more sideshoots, a more compact plant and a different tri color variegation combination. Additionally, ‘Mardi Gras’ maintains a more stable foliage coloration than Aeonium arboreum Tricolor.

‘Mardi Gras’ can also be compared to the unpatented commercial variety Aeonium ‘Sunburst.’ Plants of Aeonium ‘Sunburst’ are similar to plants of ‘Mardi Gras’ in most horticultural characteristics, however, ‘Mardi Gras’ produces a significantly more compact plant and has foliage that produces a deep burgundy blush under drought or cold conditions. Additionally, ‘Mardi Gras’ maintains a more stable foliage coloration than Aeonium ‘Sunburst’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Mardi Gras’ grown outdoors in Vista, Calif. This plant is approximately 4 months old, shown in a 4 inch pot. Plants were produced under some low water stress, to induce the burgundy blush coloration mentioned as a distinctive characteristic. 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 Pantone Process Color System Guide, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Mardi Gras’ plants in a commercial greenhouse in Vista, Calif. Temperatures ranged from −1° C. to 29° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Natural light conditions were approximately 2500 to 4000 fc of light. Plants were produced under some low water stress, to induce the burgundy blush coloration mentioned as a distinctive characteristic. Measurements and numerical values represent averages of typical plant types.
