Botanical classification: Hibiscus hybrid (L.).
Variety denomination: ‘Summer in Paradise’.
BACKGROUND AND ORIGIN OF THE PLANTThe present invention relates to the new and distinct hardy, herbaceous, hibiscus plant, Hibiscus ‘Summer in Paradise’ hybridized under direction of the inventor on Jul. 23, 2012 at a wholesale perennial nursery in Zeeland, Mich. The new plant is a single seedling selected from a cross between a proprietary unreleased rose mallow known by the breeder code 11-42 times ‘Jazzberry Jam’ (not patented). The seeds were harvested in the fall of 2012 and the specific seedling which passed the initial trial in the summer of 2014 at which time it was assigned the breeder code labeled # 12-135-2. Both parents have a complex mixture of species in them, comprising the species: moscheutos and coccineus. Hibiscus ‘Summer in Paradise’ was first asexually propagated in 2014 by sterile shoot-tip tissue culture at the same nursery in Zeeland, Mich. The resultant asexually propagated plants have been found to be stable and true to type in successive generations of asexual reproduction.
No plants of Hibiscus ‘Summer in Paradise’ have been sold under this or any name, either in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure been made prior to the filing of this application with the exception of that which was within one year of the filing of this application and was derived directly or indirectly from the inventor.
BRIEF SUMMARY OF THE PLANTHibiscus ‘Summer in Paradise’ differs from its parents as well as all other hardy herbaceous hibiscus known to the applicant in many traits. The most similar hibiscus in flower color known to the applicant are Hibiscus ‘Sultry Kiss’ U.S. Plant Pat. No. 23,300, ‘Cranberry Crush’ U.S. Plant Pat. No. 21,984, ‘Mars Madness’ U.S. Plant Pat. No. 27,838 and ‘Vintage Wine’ U.S. Plant Pat. No. 27,839. The new plant differs from ‘Sultry Kiss’ most significantly in having a more compact habit and more basal branching. Compared with the new plant, ‘Cranberry Crush’ has flower petals are more cupped, the petal color has a more reddish orange hue and less reddish purple and the plant habit is shorter and less broad. Compared with ‘Mars Madness’ the new plant is more upright in habit with larger flowers of a slightly different color and the foliage is more frequently five-lobed. The new plant compares with ‘Vintage Wine’ by having a more frequently five-lobed leaf rather than ovate of ‘Vintage Wine’ and the flower is larger and less reddish-purple hue. Compared with ‘Jazzberry Jam’ the new plant is more compact in habit, has flatter less ruffled petals and the flower is more hot cerise red rather than the pinkish-magenta. Comparison of the female parent is not possible as the parent was not maintained.
Hibiscus ‘Summer in Paradise’ is a unique hardy herbaceous hibiscus with the following combined traits:
-
- 1. Winter-hardy, perennial with upright habit of multiple, well-branched, basal stems.
- 2. Many rotate flowers of hot cerise red produced from bottom to top of plant.
- 3. Flower petals having darker red eye zone set off with column of bright yellow pollen.
- 4. Dark green, deeply-incised, tri- to penta-lobed foliage blushed with greyed reddish-purple.
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.
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. The new plant, Hibiscus ‘Summer in Paradise’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of three-year-old plants in the loamy-sand, open-field full-sun trials of a nursery in Zeeland, Mich. with supplemental fertilizer and water as needed. The plants are of natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year.
