plant named ‘Sultry Kiss’

Abstract

The new and distinct plant cultivar of hardy Hibiscus named ‘Sultry Kiss’ comprising heavily branched purple tinted stems containing three-lobed maple-like foliage with burgundy tinting, and flowers with heavily overlapped magenta red petals and crimson red eye, over at least 12 weeks during the summer and early fall until frost.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Sultry Kiss’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy hibiscus plant, Hibiscus ‘Sultry Kiss’ hybridized by Kevin A. Hurd in the summer of 2006 at a nursery in Zeeland, Mich. The new Plant, originally assigned the breeder identification number 06-210-01 is a cross between Hibiscus ‘Fantasia’ U.S. Plant Pat. No. 11,853 as the female parent (pod parent) times Hibiscus ‘Fireball’ U.S. Plant Pat. No. 13,634 as the male parent (pollen parent). Hibiscus ‘Sultry Kiss’ has been asexually propagated both by shoot tip stem cuttings and sterile tissue culture at the same nursery in Zeeland, Mich. first since 2008. The resultant plants have been found to be stable and true to type in successive generations of asexual reproduction.

SUMMARY OF THE PLANT

Hibiscus ‘Sultry Kiss’ differs from its parents as well as all other hardy hibiscus known to the applicant in many traits. The flower of ‘Sultry Kiss’ is more ruffled producing heavier substance petals of magenta red with a darker eye of crimson red, whereas ‘Fireball’ flower is red with a red eye similar to the petal color, and ‘Fantasia’ is lavender pink with a fuchsia eye. Flower size of ‘Sultry Kiss’ is intermediate the two parents, larger than ‘Fantasia’ but not quite as large as ‘Fireball’. The petals of ‘Sultry Kiss’ overlap much more than ‘Fireball’ and are similar in overlap to those of ‘Fantasia’. The flower depth of ‘Sultry Kiss’ is closer to that of ‘Fantasia’ whereas ‘Fireball’ is much flatter. The foliage of ‘Sultry Kiss’ is a dark green with tinting of purple, similar to ‘Fireball’ whereas ‘Fantasia’ has much less purple tinting in the foliage. The foliage shape of ‘Sultry Kiss’ is variable, depending on the time of year and position on the stem. It is most frequently tri-lobed, but may also be ovate with an acute apex and rarely 5-lobed. Foliage of ‘Fantasia’ is most often ovate and ‘Fireball’ most often 5-lobed. The most similar hibiscus known to the applicant is ‘Lord Baltimore’ (not patented) with bright red flowers and green dissected foliage it differs from ‘Sultry Kiss’ which has a duller red flower and purple tinted foliage. ‘Sultry Kiss’ also has purple stems compared to the solid green stems of ‘Lord Baltimore’. The new plant compares to ‘Party Favor’ (U.S. Plant patent application Ser. No. 12/804,404) in being magenta red-flowered rather than pink, in having darker purple stems, smaller foliage with less dissection and in having less over-lapping petals with less ruffling.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.

FIG. 1 shows the new plant in flower during the early part of the flowering season.

GENERAL DESCRIPTION OF THE PLANT

Hibiscus ‘Sultry Kiss’ is distinct from all other Hibiscus known to the applicant in the following combined traits:

• • 1. Heavily overlapped magenta red flower petals with deep crimson eye.
  • 2. Dissected and serrated three-lobed maple-like foliage with purple tinting.
  • 3. Stems heavily branched with dark purple tinting.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
