Abstract

A distinct cultivar of Asclepias plant named ‘Charlotte's Blush’, characterized by its white, cream, pink, and green variegated leaves and seed pods; blooms are brightly colored; it grows well in full sun to light shade.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Asclepias plant, botanically known as Asclepias curassavica, and hereinafter referred to by the cultivar name ‘Charlotte's Blush’.

The new Asclepias was discovered as a sport of an Asclepias curassavica in the Inventor's butterfly farm garden in Brooker, Fla. in the spring of 2012, and differs from the parent Asclepias curassavica in the presence of variegated leaves and seed pods in shades of green, cream, beige, and yellow that also exhibit tinges of pink coloration.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings taken at the butterfly farm garden in Brooker, Fla. in the spring of 2012. Several hundred plants of the new cultivar were grown from stem cuttings for over a year and several generations. This continued propagation has shown that the unique characteristics of this cultivar are stable and reproduced true to type via cuttings in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Charlotte's Blush’ have been grown under low light and high light conditions. The phenotype may vary somewhat with variations in environment such as light intensity and temperature. Under some light and temperatures, the intensity of the pink color will vary, such as being less intense when grown in low sunlight and more intense when grown in full sun. It has been grown in pots and in soil.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Charlottes Blush’. These characteristics in combination distinguish ‘Charlotte's Blush’ as a new and distinct cultivar of Asclepias.

• • 1. ‘Charlotte's Blush’ exhibits variegated leaves with centers in shades of green that may vary from light to dark and with creamy margins and central vein in shades of cream, beige, and/or yellow, with tinges of pink and/or fuchsia.
  • 2. ‘Charlotte's Blush’ exhibits variegated seed pods that include two or more of the following colors: pink; green shades, light to dark; cream/beige, and yellow.

‘Charlotte's Blush’ was observed to be unique from the parent Asclepias curassavica plant from which it was derived, and from all other known Asclepias curassavica cultivars, in having distinct leaf variegation and seed pod variegation including, in addition to shades of green, shades of cream, beige and/or yellow and shades of pink and/or fuchsia. The pink coloration is more intense when grown in high light. All other known A. curassavica plants and even other species have solid green leaves. Like other Asclepias curassavica, ‘Charlotte's Blush’ also has orange blooms, as described in greater detail below.

In addition, ‘Charlotte's Blush’ grows well in full sun to light shade, blooms with bright orange and yellow flowers, and has uniform flowering within the florescence. Plants of the cultivar ‘Charlotte's Blush’ also grow well in pots as well as in the ground and exhibit good post-production longevity.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new cultivar showing the colors as true as possible. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describes the colors of the new Asclepias. The photographs were taken of plants grown outdoors in Brooker, Fla.

The photograph in FIG. 1 is a side view of ‘Charlotte's Blush’ growing in the ground in full sun. The photograph shows the variegated leaves of ‘Charlotte's Blush’.

FIG. 2 is a photograph of a close-up view of a seed pod of ‘Charlotte's Blush’ growing in the ground in full sun. The cream and green variegation is visible in this photograph, as well as pink coloration on the tip of the seed pod.

The photograph in FIG. 3 shows ‘Charlotte's Blush’ growing in a pot in partial shade. Pink and fuchsia are more visible among the white, cream, and green leaves in this photograph. Although the intensity of the pink coloration tend to be more intense in plants grown in full sun, the color shows better in photographs taken in lower light.

FIG. 4 is a close-up photograph of blooms of ‘Charlotte's Blush’ growing in the ground in full sun, with the variegated leaves visible in the background.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements, and values describe plants of the new cultivar grown as stem cuttings at the butterfly farm garden in Brooker, Fla. The plants were grown under average day temperatures of 15° to 48° C. and average night temperatures of 1.6° to 26° C. The phenotype of the new cultivar may vary with variations in environmental, climatic and cultural conditions.
