‘Aruba Sunrise’

A new and distinct Kalanchoe cultivar named ‘Aruba Sunrise’ is disclosed, characterized by unique bi-color flowers of magenta-rose with feathery white aspices. Plants are robust, with an upright, uniform habit. Flowering is abundant and begins early. Foliage is olive green, with a bronze blush appearing under bright light conditions. Kalanchoe is a popular genus, typically produced for the floriculture industry, as well as for uses as container plants for the patio, or as landscape plants. The new variety is suitable for both indoor and outdoor ornamental uses.

Description

Latin name of the genus and species: Kalanchoe blossfeldiana.

Variety denomination: ‘ARUBA SUNRISE’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the unpatented, proprietary seed parent, Kalanchoe ‘Early Pink’ with the pollen parent an unpatented, proprietary Kalanchoe blossfeldiana referred to as Kalanchoe ‘Little Sun’. The cross pollination was made in September of 2013 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘Aruba Sunrise’ was discovered by the inventor, Renee O' Connell in February of 2014 in Vista, Calif., at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Aruba Sunrise’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in April 2014. Kalanchoe ‘Aruba Sunrise’ 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 ‘Aruba Sunrise’ 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 ‘ARUBA SUNRISE’. These characteristics in combination distinguish ‘ARUBA SUNRISE’ as a new and distinct Kalanchoe cultivar:

    • 1. Kalanchoe ‘Aruba Sunrise’ produces flowers that are bicolor, near magenta-rose, tipped by a rose-tinted white feathering at the apices, an unusual floral color combination for Kalanchoe blossfeldiana.
    • 2. Kalanchoe ‘Aruba Sunrise’ is characterized by upright, uniform and robust growth.
    • 3. Kalanchoe ‘Aruba Sunrise’ displays an early and freely flowering habit.
    • 4. Kalanchoe ‘Aruba Sunrise’ is characterized by glossy, dark olive green leaves, displaying a bronze blush in bright light.

PARENTAL COMPARISON

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

    • 1. ‘Aruba Sunrise’ exhibits more robust growth than ‘Early Pink’.
    • 2. ‘Aruba Sunrise’ produces bicolored flowers, whereas Kalanchoe ‘Early Pink’ has solid flowers.
    • 3. ‘Aruba Sunrise’ has better postproduction longevity than ‘Early Pink’.
    • 4. ‘Aruba Sunrise’ displays a dark, glossy leaf texture as compared to the matte texture of the ovate leaf blade of Kalanchoe ‘Early Pink’

Plants of the new cultivar ‘Aruba Sunrise’ are similar to the pollen parent in most horticultural characteristics. However, plants of the new cultivar ‘Aruba Sunrise’ differ in the following:

    • 1. Kalanchoe ‘Little Sun’ produces small bicolored flowers, involving the colors of light yellow, salmon and white, whereas ‘Aruba Sunrise’ produces flowers that are magenta-rose, tipped by a rose-tinted white feathering at the apices.
    • 2. ‘Aruba Sunrise’ produces more slender leaf blades than ‘Little Sun’.
    • 3. ‘Aruba Sunrise’ produces more branches than ‘Little Sun’.
    • 4. ‘Aruba Sunrise’ produces flowers that are somewhat larger than those of ‘Little Sun’.

COMMERCIAL COMPARISON

The new cultivar ‘Aruba Sunrise’ can be compared to the patented commercial variety Kalanchoe ‘Reese’, U.S. Plant Pat. No. 21,521. Plants of the Kalanchoe ‘Reese’ are similar to plants of the new cultivar ‘Aruba Sunrise’ in most horticultural characteristics. However, the new cultivar ‘Aruba Sunrise’ differs in the following:

    • 1. ‘Aruba Sunrise’ displays bicolor magenta-rose flowers with white feathering on the petal apices, whereas the flowers of Kalanchoe ‘Reese’ are orange in color.
    • 2. ‘Aruba Sunrise’ produces leaves that are more narrow in width, often 3.5 cm wide at the widest point, versus those of Kalanchoe ‘Reese’, which can be 5.5 cm wide at the widest point.
    • 3. ‘Aruba Sunrise’ expresses a copper bronze tint overlay on the green leaves, whereas Kalanchoe ‘Reese’ exhibits green leaves without the copper bronze tint.
    • 4. Grown side by side, plants of ‘Aruba Sunrise’ had 7 offsets in a 13 cm pot, whereas ‘Reese’ had only 4 offsets.

The new cultivar ‘Aruba Sunrise’ can be compared to the unpatented commercial variety Kalanchoe blossfeldiana ‘Drew’. Plants of Kalanchoe ‘Drew’ are similar to plants of the new cultivar ‘Aruba Sunrise’ in most horticultural characteristics. However, the new cultivar ‘Aruba Sunrise’ differs in the following:

    • 1. ‘Aruba Sunrise’ displays bicolor magenta-rose flowers with white feathering on the petal apices, whereas the flowers of Kalanchoe ‘Drew’ are pink in color.
    • 2. ‘Aruba Sunrise’ produces leaves that are more narrow in width, often 3.5 cm wide at the widest point, versus those of Kalanchoe ‘Drew’, which can be 7 cm wide at the widest point.
    • 3. ‘Aruba Sunrise’ expresses a copper bronze tint overlay on the green leaves, whereas ‘Drew’ exhibits green leaves without the copper bronze tint.
    • 4. Grown together, plants of ‘Aruba Sunrise’ had 7 offsets in a 13 cm pot, whereas plants of ‘Drew’ had only 3 offsets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 and FIG. 2 illustrate in full color typical plants of ‘ARUBA SUNRISE’ grown in a commercial 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 Kalanchoe plant. The following photographs depict plants grown under natural light conditions of 3000-3500 foot-candles. Temperatures ranged from 3° C. to 39° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.

FIG. 1 illustrates in full color the side view of a typical plant of Kalanchoe ‘Aruba Sunrise’ grown in moderate light, with just a hint of bronze coloration.

FIG. 2 illustrates in full color a close up of individual flowers and inflorescence of the new variety.
