USPP29566P2 - Aeonium ‘Tenerife Rose’ - Google Patents

Abstract

A new and distinct Aeonium cultivar named ‘Tenerife Rose’ is disclosed, characterized by green foliage distinctively margined with a dark bronze color. Offsets are formed in distinctive vertical tiers, producing a more columnar plant. Plants are robust and grow quickly., while maintaining an attractive compact habit. Aeonium is, typically produced as a container plant for the patio or for landscape use.

Description

Latin name of the genus and species: Aeonium hybrida.

Variety denomination: ‘TENERIFE ROSE’.

BACKGROUND OF THE INVENTION

The new cultivar, Aeonium ‘Tenerife Rose’, was found by the inventor, Renee O'Connell, as the result of a crossing made January 2012 as part of a planned breeding program. The seed parent variety is the unpatented proprietary variety referred to as Aeonium hybrida ‘Cat 07’. The pollen parent is the unpatented variety Aeonium hybrida ‘Bordeaux’. Aeonium ‘Tenerife Rose’ was selected by the inventor, Renee O Connell, in April of 2013 from a group of seedlings resulting from the 2013 crossing, at a commercial greenhouse in Vista. Calif.

Asexual reproduction of the new cultivar ‘Tenerife Rose’ was first performed in Vista, Calif., at a commercial greenhouse, by vegetative off-sets in October of 2013. ‘Tenerife Rose’ 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 ‘TENERIFE ROSE’ 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 ‘TENERIFE ROSE’ These characteristics in combination distinguish ‘TENERIFE ROSE’ as a new and distinct Aeonium cultivar:

• • 1. Fast, robust growth, more so than many other Aeonium species and cultivars.
  • 2. Aeonium ‘Tenerife Rose’ freely offsets, producing tiers of offsets to quickly form a desirable specimen for the landscape
  • 3. Aeonium ‘Tenerife Rose’, rather than clustering laterally as do many comparable Aeoniums, produces tiers of offsets more vertically, continuing to produce offsets towards the apical meristem of the plant.
  • 4. Aeonium ‘Tenerife Rose’, as a result of the habit of producing more of a columnar morphology, is better suited as a centerpiece in a garden or dish garden planting, than many other comparable Aeoniums.

COMPARISON TO PARENTS

Plants of the new cultivar ‘TENERIFE ROSE’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘TENERIFE ROSE’ differ in the following;

• • 1. Aeonium ‘Tenerife Rose’ exhibits a more columnar morphology than the seed parent.
  • 2. Aeonium ‘Tenerife Rose’ produces rosettes of leaves of a medium green, distinctively outlined with a darker color, whereas the leaves of Aeonium ‘Cat 07’ are a dark brownish color.
  • 3. Aeonium ‘Tenerife Rose’ exhibits offsets towards the apical meristem of the plant, whereas Aeonium ‘Cat 07’ produces offsets mostly approximately halfway up the plant, and does not continue to produce offsets towards the apical meristem.
  • 4. Aeonium ‘Tenerife Rose’ grows faster than Aeonium ‘Cat 07’.
  • 5. Aeonium ‘Tenerife Rose’ produces more offsets than does Aeonium ‘Cat 07’.

Plants of the new cultivar ‘TENERIFE ROSE’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘TENERIFE ROSE’ differ in the following;

• • 1. Aeonium ‘Tenerife' Rose’ produces rosettes that are a slightly darker green than those of Aeonium ‘Bordeaux’.
  • 2. Aeonium ‘Bordeaux’ offsets freely, but tends to produce the offsets laterally, whereas Aeonium ‘Tenerife Rose’ produces the offsets more vertically.
  • 3. Aeonium ‘Tenerife Rose’ exhibits a distinctive darker leaf margin, whereas Aeonium ‘Bordeaux’ displays a more subtle difference between the margin/blush and the green color.
  • 4. Aeonium ‘Bordeaux’ grows to approximately 12″ in height, whereas Aeonium hybrid ‘Tenerife Rose’ grows to approximately 18″ in height.

COMMERCIAL COMPARISON

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

• • 1. Aeonium ‘Tenerife Rose’ grows more upright than does Aeonium ‘Escondido’, producing a specimen that is taller in height.
  • 2. Aeonium ‘Escondido’ produces offsets laterally, whereas Aeonium ‘Tenerife Rose’ continues to produce offsets near the apical meristem, resultant in a more vertical growth of the offsets in relation to the principal plant.
  • 3. Aeonium ‘Tenerife Rose’ forms rosettes of green leaves, with distinctive darker margins and darker overall blush in strong light, whereas Aeonium ‘Escondido’ produces rosettes of green leaves with a ruddy blush and margins.

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

• • 1. Aeonium ‘Tenerife Rose’ begins to offset when the plant is only 8″ or so in height, whereas Aeonium ‘Zwartkop’ does not offset until it is taller.
  • 2. Aeonium ‘Tenerife Rose’ produces offsets freely, often in multiple tiers that create an aesthetically appealing cluster, whereas Aeonium ‘Zwartkop’ produces less offsets, and does not produce the offsets in multiple tiers, resultant in a lankier plant that does not display the pleasing appearance of a “full cluster”.
  • 3. Aeonium ‘Tenerife Rose’ forms rosettes of medium green leaves with a distinct darker margin and a darker blush in strong light, whereas Aeonium ‘Zwartkop’ forms rosettes of dark, nearly black leaves.
  • 4. Aeonium ‘Tenerife Rose’ can fill a production pot with an attractive cluster with one cut in several months, whereas it is necessary to plant multiple plantlets of Aeonium ‘Zwartkop’ in the production pot to give the impression of “branching”, resulting in higher production costs.
