A poinsettia named 'Variegated-Leaf Success,' cultivated as a natural sport of Euphorbia pulcherrima by Franz Fruehwirth, Ecke Ranch's chief hybridizer, has variegated leaves and bright red flower bracts.
On March 22, 1996, Franz Fruehwirth filed an application with the United States Patent and Trademark Office for a patent for a poinsettia named 'Variegated-Leaf Success.' The inventor named Paul Ecke Ranch Inc., in Encinitias, southern California, as assignee. Howard J. Locker was the application's primary examiner. On Aug. 5, 1997, the U.S. Patent and Trademark Office assigned plant patent number 9,990 to a poinsettia named 'Variegated-Leaf Success.'
A poinsettia named 'Variegated-Leaf Success' originated as a natural sport of poinsettia plant '559.' Poinsettia '559' was an induced, self-branching sport of seedling 'H-18,' a proprietary, unpatented plant in the Ecke Ranch greenhouse in Encinitas.
Fruethwirth selected 'Variegated-Leaf Success' from among several thousand '559' poinsettias in 1994. The inventor based his selection upon the sport's strikingly variegated leaves and bright red flower bracts. Vegetative propagation via stem cuttings confirmed the retention and true reproduction of the sport's desirable traits over successive generations.
Fruehwirth's patent application describes poinsettia 'Variegated-Leaf Success' in December 1995. Flowering plants were grown as one branched plant in a pot with a diameter of 14 centimeters (5.51 inches) and a height of 11 centimeters (4.33 inches).
The short shrub reached an overall height of 38 centimeters (14.96 inches). Its spread, or overall width, measured 33 centimeters (12.99 inches).
The upright, single-stemmed plant exhibits self-branching side shoots. Axillary branches do not require pinching in order to develop their terminal inflorescences. Fruehwirth, though, recommends pinching for fast, uniform develoment of axillary branches.
The poinsettia named 'Variegated-Leaf Success' logs a response period of about 10 weeks. The flowering response period is triggered by continuous long night conditions and night temperatures of 16 to 18 degrees Celsius (60.8 to 64.4 degrees Fahrenheit).
Medium-sized leaves typically measure 15 to 16 centimeters (5.90 to 6.29 inches) in length. Blade width typically is 10 to 11 centimeters (3.93 to 4.33 inches).
Leaf shape is usually ovate, or egg-shaped. The blade's margins are described as mostly entire, with smooth, untoothed edges.
A leaf's variegation may comprise sometimes two, but mostly three, different colors. Blade colors generally appear as dark green, light green and light yellow. The yellow color tends to occur at the blade's periphery.
Upper surfaces have a dark greenness (darker than Royal Horticultural Society color chart color 147A). Other color zones are light green, nearly brown green (RHS 148B), and yellow, lighter than brown green (RHS 153D).
Foliage displays good retention. The low light intensities characteristic of consumers' homes do not interfere with leaf longevity.
Variously sized bracts, numbering about 12 to 15, subtend, or underlie, the 'Variegated-Leaf Success' poinsettia's cuplike floral structure, known as a cyathium. Medium- to large-sized primary bracts typically are 18 centimeters (7.08 inches) in length. Their typical width is 12 centimeters (4.72 inches).
Primary bracts are ovate, or egg-shaped. One indentation, on either side of the bract, lobes each primary bract.
Secondary bracts have shapes that are ovate to elliptical. Their smooth, untoothed margins are described as entire.
Upper surfaces of bracts have a bright red coloring (near RHS 45B). Lower surfaces are red (near RHS 46C).
In full bloom, 'Variegated-Leaf Success' poinsettia generally features 10 to 12 cyathia. Each cyathium measures about 6 millimeters (0.236 inches) in length by 5 millimeters (0.196 inches) in width.
Cyathias are green, with red fringes at the distal, or outer, ends. Protruding from the side of each cyathium is a yellow nectar cup. Nectar exudate, or secretion, is abundantly present.
The takeaway for a poinsettia named 'Variegated-Leaf Success' is its good flowering response period, its distinctive palette of variegated leaves and bright red bracts, its attractive self-branching habit and its good retention of bracts and leaves.
A poinsettia named 'Variegated-Leaf Success,' which has variegated leaves, shows that unusual leaf color zones are interesting contributors to the poinsettia palette.
