USPP27613P3 - Aeonium plant named ‘Emerald Ice’ - Google Patents

Abstract

A new and distinct Aeonium cultivar named ‘Emerald Ice’ is disclosed, characterized by very even, concentric rosettes, comprised of an abundance of green leaves, colored marginally with creamy white, and arranged in an attractive, variegated geometric pattern. Further, the new cultivar ‘Emerald Ice’ freely offsets, enabling increased and faster propagation of the cultivar. In addition, the robust growth, in combination with the freely offsetting characteristic of the new cultivar ‘Emerald Ice’, results in the clusters at an early age, and enhances production intervals. The new variety is an Aeonium, part of the Crassulaceae complex that includes Aeonium, Echeveria, Graptopetalum, Sedum and others. Aeonium is a popular genus, typically produced as container plants for the patio or as landscape plants.

Description

Latin name of the genus and species: Aeonium hybrid.

Variety denomination: ‘EMERALD ICE’.

BACKGROUND OF THE INVENTION

The new cultivar, Aeonium ‘Emerald Ice’, was found by the inventor, Renee O'Connell, as a naturally occurring, whole plant, mutation in an existing population of the unpatented variety Aeonium hybrid ‘Party Platter’. The parent variety is the product is a planned breeding program conducted same inventor, Renee O'Connell. Aeonium ‘Emerald Ice’ was discovered by the inventor, Renee O Connell, in November of 2011, in a block of motherstock plants of Aeonium ‘Party Platter’ at a commercial greenhouse in Vista. Calif.

Asexual reproduction of the new cultivar ‘Emerald Ice’ was first performed in Vista, Calif., at a commercial greenhouse, by vegetative cuttings in December of 2011. ‘Emerald Ice’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘EMERALD ICE’ 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 ‘EMERALD ICE’ These characteristics in combination distinguish ‘EMERALD ICE’ as a new and distinct Aeonium cultivar:

• • 1. Displays a low growing morphology, in combination with variegation, not exhibited by other known Aeonium cultivars.
  • 2. Exhibits very concentric, flattened rosettes with an abundance of leaves, combining with the variegation to create an unusual geometric pattern, not displayed by comparable Aeonium cultivars.
  • 3. Freely offsetting, forming low growing clusters quickly, a growth habit not displayed by comparable Aeonium cultivars.
  • 4. Easily and rapidly propagated due to robust growth, and prolific offsetting, as compared with other Aeonium cultivars.

Plants of the new cultivar ‘EMERALD ICE’ are similar to plants of the parent, Aeonium ‘Party Platter’ in most horticultural characteristics, however, plants of the new cultivar ‘EMERALD ICE’ differ in the following;

• • 1. Displays a green and creamy white variegation, displaying leaves of multiple green shades accented by creamy white margins; foliage of Aeonium ‘Party Platter’ is not variegated.
  • 2. Forms rosettes that are of more compact morphology than the rosettes of Aeonium ‘Party Platter’.
  • 3. Exhibits a more geometric appearance than that of Aeonium ‘Party Platter’, as a result of the more compact rosette in combination with the attractive variegation.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘EMERALD ICE’ are comparable to the unpatented, commercial variety Aeonium arboreum ‘Tricolor’. The two Aeonium varieties are similar in most horticultural characteristics; however, the new variety ‘EMERALD ICE’ differs in the following:

• • 1. Displays a more geometric variegation than does Aeonium arboreum ‘Tricolor’.
  • 2. Forms a more evenly concentric rosette than does Aeonium arboreum ‘Tricolor’, producing a more uniform rosette plant form.
  • 3. Produces a rosette with an abundance of leaves, creating a plant with a much more full appearance, than does Aeonium arboreum ‘Tricolor’
  • 4. Offsets more profusely than Aeonium arboreum ‘Tricolor’, enhancing the propagation rate, and producing a morphologically aesthetic cluster.

Plants of the new cultivar ‘EMERALD ICE’ can also be comparable to the unpatented commercial variety Aeonium ‘Sunburst’. The two Aeonium varieties are similar in most horticultural characteristics; however, the new variety ‘EMERALD ICE’ differs in the following:

• • 1. Displays a more geometric variegation than does Aeonium ‘Sunburst.
  • 2. Forms a more evenly concentric rosette than does Aeonium ‘Sunburst’, producing a more uniform rosette plant form.
  • 3. Produces a rosette with an abundance of leaves, creating a plant with a much more full appearance, than does Aeonium ‘Sunburst’.
  • 4. Offsets more profusely than does Aeonium ‘Sunburst’, enhancing the propagation rate, and producing a morphologically aesthetic cluster.
