USPP28621P2 - Sedum plant named ‘Wildfire’ - Google Patents

Abstract

A new cultivar of Sedum plant named ‘Wildfire’ characterized by its variegated foliage that emerges with a tri-color look of green, pink and yellow in the spring and turns bright shiny cherry red in color with bright orange-pink margins as it matures in full sun with color retention throughout the entire growing season, its heavy branching with branches from every leaf node along the stems producing a mounded groundcover-type plant habit with no open centers and that does not flop in the summer, and its large inflorescences that are pink in color and appear in late summer.

Description

Botanical classification: Sedum hybrid.

Variety denomination: ‘Wildfire’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically of hybrid origin and known as Sedum ‘Wildfire’ and referred to hereinafter by its cultivar name, ‘Wildfire’. The new cultivar of Sedum is a hardy herbaceous perennial grown for use as a landscape and container plant and is particularly suitable as a groundcover.

The Inventor discovered the new cultivar in November of 2013 as a naturally occurring branch mutation of Sedum ‘Firecracker’ (U.S. Plant Pat. No. 26,595) that was growing in a 72-cell plug tray at his nursery in Hudsonville, Mich.

Asexual propagation of the new cultivar was first accomplished by stem tip cuttings in March of 2014 in Hudsonville, Mich. Asexual propagation by stem tip cuttings has determined the characteristics to be stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Wildfire’ as a unique cultivar of Sedum.

• • 1. ‘Wildfire’ exhibits variegated foliage that emerges with a tri-color look of green, pink and yellow in the spring and turns bright shiny cherry red in color with bright orange-pink margins as it matures in full sun (yellow edges when grown in shade) with color retention without fading throughout the entire growing season.
  • 2. ‘Wildfire’ exhibits heavy branching with branches from every leaf node along the stems producing a mounded groundcover-type plant habit with no open centers and that does not flop in the summer.
  • 3. ‘Wildfire’ exhibits a very vigorous vegetative bud production when entering winter dormancy in early November with at least 50 new growth buds in a 30-cell plug.
  • 4. ‘Wildfire’ exhibits large inflorescences that are pink in color and appear in late summer.

The parent of ‘Wildfire’, ‘Firecracker’, is similar to ‘Wildfire’ in having similar inflorescences and in plant habit. ‘Firecracker’ differs from ‘Wildfire’ in having leaves with no variegation that are solid red in color. ‘Wildfire’ can be most closely compared to the Sedum cultivar ‘Lime Twister’ (U.S. Plant Pat. No. 26,895) and the Sedum spurium cultivar ‘Tricolor’ (not patented). Both cultivars are similar to ‘Wildfire’ in having variegated foliage and in having a mounded groundcover-type plant habit. ‘Lime Twister’ differs from ‘Wildfire’ in having foliage that is green in color with margins that are creamy yellow-white in color, in having a plant size that is 20% smaller, in having leaves that are 30% smaller in size and in having flowers that are lighter pink in color. ‘Tricolor’ differs from ‘Wildfire’ in having leaves that is blue-green in color with margins that are creamy white-pink in color, 75% smaller in size and thinner in substance, in having a plant height that is 40% smaller, and in having inflorescences that are smaller in size, lighter pink in color and an earlier blooming period.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Sedum. The photographs were taken of a plant about 5 months in age (from a 30-cell plug) as grown outdoors in a 1-gallon container in Hudsonville, Mich.

The photograph in FIG. 1 provides a view of the foliage of ‘Wildfire’ in spring.

The photograph in FIG. 2 provides a view of the plant habit and foliage coloration of ‘Wildfire’ in summer through fall when grown in full sun.

The photograph in FIG. 3 provides a close-up view of the inflorescences of ‘Wildfire’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Sedum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar as observed on 3 month-old plants of ‘Wildfire’ as grown outdoors in two-quart containers in Hudsonville, Mich. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
