A new and distinct Echeveria cultivar named ‘ECRRE02-0’ is disclosed, characterized by tight rosulate plant form, unique heavily crenulated leaf margins. Foliage is colored greyed-green with red margins and greyed-red margin flushing. The new variety is an Echeveria, normally produced as an ornamental garden or container plant.

Latin name of the genus and species:Echeveria gibbiflora.

BACKGROUND OF THE INVENTION

The newEcheveriacultivar is a product of a planned breeding program conducted by the inventor, John Oates, in Thirlmere, Australia. The objective of the breeding program was to produce newEcheveriavarieties for ornamental commercial applications. The new variety is a product of cross breeding that occurred on May 5, 2005, at a commercial nursery in Thirlmere, Australia.

The seed parent is the unpatented, proprietary seedling variety ofEcheveria gibbiflora×derenbergii, ‘Line 540’. The pollen parent is the unpatented, proprietary seedling varietyEcheveria gibbiflora, ‘Line 546’. The new variety was discovered during October of 2006 by the inventor in a group of seedlings resulting from the 2005 crossing, in a commercial nursery in Thirlmere, Australia.

Asexual reproduction of the new cultivar has been performed by tissue culture. This was first performed at a laboratory in Tumbi Umbi, Australia in March of 2008 and has shown that the unique features of this cultivar are stable and reproduced true to type in 15 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ECRRE02-0’ 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 ‘ECRRE02-0’. These characteristics in combination distinguish ‘ECRRE02-0’ as a new and distinctEcheveriacultivar:1. Leaf margin colored red with greyed-red flushing.2. Leaf color fades from bright green to pale green with an increase in temperature.3. Rosulate plant form, no branching.4. Leaf margin heavily crenulated.

PARENT COMPARISON

Plants of the new cultivar ‘ECRRE02-0’ are similar to plants of the seed parentEcheveria gibbiflora×derenbergii, ‘Line 540’ in most horticultural characteristics, however, plants of the new cultivar ‘ECRRE02-0’ produce a leaf margin which is crenulated, compared to the undulating margin of the seed parent. Additionally, ‘ECRRE02-0’ also produces leaf margins of a somewhat different coloration than those of the seed parent.

Plants of the new cultivar ‘ECRRE02-0’ are similar to plants of the pollen parent;Echeveria gibbiflora‘Line 546’ in most horticultural characteristics, however, plants of the new cultivar ‘ECRRE02-0’ produce a leaf margin which is crenulated, compared to the undulating margin of the pollen parent. Additionally ‘ECRRE02-0’ also produces leaf margins of a different coloration than those of the seed parent.

COMMERCIAL COMPARISON

‘ECRRE02-0’ can be compared to the commercial varietyEcheveria gibbiflora‘ECRPI01-0’, filed concurrently, having application Ser. No. 13/987,157. Plants of ‘ECRRE02-0’ are similar to plants of ‘ECRPI01-0’ in most horticultural characteristics, however, plants of ‘ECRRE02-0’ produce leaves with a more crenulated margin than ‘ECRPI01-0’. Overall leaf aspect is less undulating in ‘ECRRE02-0’ than the leaf aspect of ‘ECRPI01-0’. Additionally, margin coloration is somewhat different between the new varieties.

‘ECRRE02-0’ can be compared to the commercial varietyEcheveria gibbiflora‘ECRAQ03-0’, filed concurrently, having application Ser. No. 13/987,155. Plants of ‘ECRRE02-0’ are similar to plants of ‘ECRAQ03-0’ in most horticultural characteristics, however, plants of ‘ECRRE02-0’ produce leaves with a crenlated margin, compared to the tightly undulating margin of ‘ECRAQ03-0’. Additionally, foliage coloration is significantly different.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘ECRAQ03-0’ plants grown in a greenhouse in Oxnard, Calif.
