plant named ‘Blue Sprite’

Abstract

A new and distinct Sedeveria cultivar named ‘Blue Sprite’ is disclosed, characterized by a compact concentric, chunky rosette, and unique stem bifurcation which can fill a 9 cm pot with a single vegetative cutting. Thickened blue-green leaves, with enhanced apical rose red blushing. Suitability for combining with other ornamental plants. The new variety would typically be useful as container a plant or as landscape plants.

Description

Latin name of the genus and species: Sedeveria hybrid.

Variety denomination: ‘BLUE SPRITE’.

BACKGROUND OF THE INVENTION

The new cultivar, Sedeveria ‘Blue Sprite’, is the product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented, seed parent, Echeveria hybrid known as ‘BEM 11-27’ with the pollen parent, an unpatented, hybrid Sedum ‘SP 9-12’ The cross pollination was made during June 2014, in Vista, Calif., at a commercial greenhouse. The new cultivar ‘Blue Sprite’ was discovered by the inventor, Renee O'Connell, in August 2015, in Vista, Calif., at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Blue Sprite’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in Fall of 2017. Sedeveria ‘Blue Sprite’ 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 ‘Blue Sprite’ 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 ‘BLUE SPRITE’. These characteristics in combination distinguish ‘BLUE SPRITE’ as a new and distinct Sedeveria cultivar:

• 1. Sedeveria ‘Blue Sprite’ produces compact rosettes of thickened leaves, displaying a very “chunky” appearance, not expressed to this extent commonly by other Sedeveria, Sedums or Echeveria.
• 2. Sedeveria ‘Blue Sprite’ displays very thickened blue-green leaves, with enhanced apical rose red blushing, a condition accentuated by bright light, cooler temperatures and drought.
• 3. Sedeveria ‘Blue Sprite’ exhibits a rather unusual trait of bifurcation of the stem, producing multi-headed clusters, as compared to many other Echeveria and Sedum and hybrids.

PARENTAL COMPARISON

Plants of the new cultivar ‘Blue Sprite’ are similar to the seed parent in most horticultural characteristics. However, plants of the new cultivar ‘Blue Sprite’ differ in the following:

• 1. Sedeveria ‘Blue Sprite’ exhibits stem bifurcation, whereas the Echeveria hybrid ‘BEM 11-27’ produces offsetting from the base.
• 2. ‘Blue Sprite’, due to the stem bifurcation, will form a cluster of 7 inches or more in diameter, whereas Echeveria hybrid ‘BEM 11-27’ forms a cluster that rarely exceeds 5″ in diameter.
• 4. Sedeveria ‘Blue Sprite’ expresses more intense apical blushing of the leaves than does Echeveria hybrid ‘BEM 11-27’.

Plants of the new cultivar ‘Blue Sprite’ are similar to the pollen parent, in most horticultural characteristics. However, the new cultivar ‘Blue Sprite’ differs the following:

• 1. Sedeveria ‘Blue Sprite’ displays stem bifurcation, whereas Sedum ‘SP 9-12’ produces offsetting laterally from the central rosette.
• 2. Sedeveria ‘Blue Sprite’ exhibits shorter and thickened leaves as compared to Sedum ‘SP 9-12’, contributing to a more “chunky” appearance to the rosette.

COMMERCIAL COMPARISON

The new cultivar ‘Blue Sprite’ can be compared to Sedeveria ‘Blue Elf’, unpatented’. Plants of this comparator are similar to plants of the new cultivar ‘Blue Sprite’ in most horticultural characteristics. However, the new cultivar ‘Blue Sprite’ differs in the following:

• 1. Foliage color of ‘Blue Sprite’ is blue-green with rose blushing, foliage of ‘Blue Elf’ is light grey-green-blue without significant blushing.
• 2. Plants of ‘Blue Sprite’ offset much more freely than plants of ‘Blue Elf’.
• 3. Leaves of Sedeveria ‘Blue Sprite’ are thicker than leaves of ‘Blue Elf’.

The new cultivar ‘Blue Sprite’ can be compared to Sedeveria ‘Jet Beads, unpatented’. Plants of this comparator are similar to plants of the new cultivar ‘Blue Sprite’ in most horticultural characteristics. However, the new cultivar ‘Blue Sprite’ differs in the following:

• 1. Foliage color of ‘Blue Sprite’ is blue-green with rose blushing, foliage of ‘Jet Beads’ is greyed-purple with a green base.
• 2. Plants of ‘Blue Sprite’ are more robust, and grow more densely than plants of ‘Jet Beads’.
• 3. Leaves of Sedeveria ‘Blue Sprite’ are thicker than leaves of ‘Jet Beads’.

The new cultivar ‘Blue Sprite’ can be compared to Sedeveria x Echeveria ‘Lilac Mist’, U.S. Plant Pat. No. 29,643. Plants of this comparator are similar to plants of the new cultivar ‘Blue Sprite’ in most horticultural characteristics. However, the new cultivar ‘Blue Sprite’ differs in the following:

• 1. Foliage color of ‘Blue Sprite’ is blue-green with rose blushing, foliage of ‘Lilac Mist’ is lighter grey-green-blue with lighter lavender blushing.
• 2. Plants of ‘Blue Sprite’ offset much more freely than plants of ‘Lilac Mist’.
• 3. Leaves of Sedeveria ‘Blue Sprite’ are thicker than leaves of ‘Lilac Mist

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The photograph was taken using conventional techniques and equipment. While the colors in the photograph 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 new Sedeveria ‘Blue Sprite’. The accompanying photograph illustrates in full color a plant of Sedeveria ‘Blue Sprite’, grown in a greenhouse (approximately 2500-foot candles) in Vista, Calif., in a one-quart pot.
