Abstract

A new and distinct Echeveria cultivar named ‘Arctic lace’ is disclosed, characterized by rosettes of frosted baby blue leaves with an unusual leaf shape that is uplifted towards the center of the plant. Foliage is anfractuously crenulate with a hyaline margin. The new cultivar is robust growing enabling faster production times for finished commercial pots. The new variety is an Echeveria, part of the Crassulaceae complex that includes Aeonium, Crassula, Graptopetalum, Pachyphytum, Sedum and others. Echeveria is a popular genus, typically produced as container plants for the patio or as landscape plants, as a variety of ornamental purposes.

Description

Latin name of the genus and species: Echeveria hybrid.

Variety denomination: ‘ARCTIC LACE’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘ARCTIC LACE’, is the product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented, seed parent, Echeveria ‘Aqua 4’ with the pollen parent an unpatented, proprietary variety of Echeveria referred to as ‘Dop11’. The cross pollination was made during September, 2013 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘ARCTIC LACE’ was discovered by the inventor, Renee O' Connell, in June, 2014, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘ARCTIC LACE’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in May, 2014. Echeveria ‘ARCTIC LACE’ 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 ‘ARCTIC LACE’ 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 ‘ARCTIC LACE’. These characteristics in combination distinguish ‘ARCTIC LACE’ as a new and distinct Echeveria cultivar:

    • 1. Rosettes of frosted baby blue leaves with an unusual leaf shape that is uplifted towards the center of the plant.
    • 2. The leaves with an anfractuously crenulate, hyaline margin.
    • 3. Leaves distinctively upturned towards the center of the rosette, caused by the anfractuous margins pushing the leaf apices inward.
    • 4. Fast growing as compared with many other Echeverias, enhancing production times in the commercial nursery.
    • 5. Echeveria ‘Arctic Lace’, with its unusual leaf shape that is uplifted towards the center of the plant, in combination with the anfractuous, hyaline margins displays an overall appearance of “lace”, not observed with other Echeverias.
    • 6. Echeveria ‘Arctic Lace’, due to its anfractuous, hyaline margins and icy blue color, provides an excellent accent for holiday table centerpieces, bridal bouquets and succulent arrangements, as compared to many other Echeverias.
PARENTAL COMPARISON

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

    • 1. Echeveria ‘Arctic Lace’ displays leaves that flare at the apices, and fold slightly downward at the sides to create the appearance of a “fluted” leaf, whereas Echeveria ‘Aqua 4’ does not.
    • 2. Echeveria ‘Arctic Lace’ exhibits less afractuity than does the seed parent Echeveria ‘Aqua 4’.
    • 3. The hyaline margin of the leaves of Echeveria ‘Arctic Lace’ is wider than the hyaline margin of Echeveria ‘Aqua 4’.
    • 4. Echeveria ‘Arctic Lace’ grows faster than Echeveria hybrid ‘Arctic Lace’.
    • 5. Echeveria ‘Arctic Lace’ displays a morphology of upswept, fluted leaves, whereas Echeveria ‘Aqua 4’ does not exhibit upswept, fluted leaves.

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

    • 1. Echeveria ‘Arctic Lace’ displays very anfractuous leaf margins, whereas Echeveria ‘Dop11’ does not.
    • 2. Echeveria ‘Arctic Lace’ exhibits hyaline leaf margins, whereas Echeveria ‘Dop11’ shows no differentiation in color between leaf and leaf margin.
    • 3. Echeveria ‘Arctic Lace’ has flowers that are smaller than those of Echeveria ‘Dop11’.
    • 4. Echeveria ‘Arctic Lace’ grows somewhat taller than Echeveria ‘Dop11’, with more upswept appearance to the apical tips of the leaves, whereas Echeveria ‘Dop11’ forms a more flattened rosette, with less upswept curvature of the leaves.
COMMERCIAL COMPARISON

The new cultivar ‘Arctic Lace’ can be compared to the unpatented commercial variety Echeveria ‘Topsy Turvy’. Plants of Echeveria ‘Topsy Turvy’ are similar to plants of the new cultivar ‘Arctic lace’ in most horticultural characteristics. However, the new cultivar ‘Arctic Lace’ differs in the following:

    • 1. Echeveria ‘Arctic Lace’ displays anfractuous leaf margins whereas the leaf margins of Echeveria ‘Topsy Turvy’ are entire, and devoid of anfractuitous crenations.
    • 2. Echeveria ‘Arctic Lace’ exhibits hyaline leaf margins, whereas the leaf margins of Echeveria ‘Topsy Turvy’ are the same color as the rest of the leaf.
    • 3. Echeveria ‘Arctic Lace’ is faster growing than Echeveria ‘Topsy Turvy’
    • 4. Echeveria ‘Arctic Lace’ does not have a “groove” down the center of the bottom of each leaf, whereas Echeveria ‘Topsy Turvy’ has a groove down the center of the bottom of each leaf.
    • 5. Echeveria ‘Arctic Lace’ does not have prominent bracts on the inflorescence, whereas Echeveria ‘Topsy Turvy’ has prominent bracts on the inflorescence.
    • 6. Echeveria ‘Arctic Lace’ has smaller flowers than those of Echeveria ‘Topsy Turvy’

The new cultivar ‘Arctic Lace’ can be compared to the unpatented commercial variety Echeveria ‘Perle von Nurnberg’. Plants of Echeveria ‘Perle von Nurnberg’ are similar to plants of the new cultivar ‘Arctic Lace’ in most horticultural characteristics. However, plants of the new cultivar ‘Arctic Lace’ differ in the following:

    • 1. Echeveria hybrid ‘Arctic Lace’ forms rosettes of icy blue, whereas the rosettes of Echeveria ‘Perle von Nurnberg’ are dusty violet in color.
    • 2. Echeveria hybrid ‘Arctic Lace’ displays very anfractuous leaf margins, whereas the margins of Echeveria hybrid ‘Perle von Nurnberg’ are entire, and are devoid of crenation.
    • 3. The rosette of Echeveria hybrid ‘Arctic Lace’ displays an upswept appearance, whereas the rosette of Echeveria ‘Perle von Nurnberg’ is more flattened in appearance.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate in full color typical plants of ‘ARCTIC LACE’ grown in a greenhouse in Vista, Calif. The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of the new Echeveria plant. The following photographs depict plants grown under natural light conditions of 2500-4000 foot-candles. Temperatures ranged from −1° C. to 29° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.
