Hibiscus plant named ‘Berrylicious’

Abstract

A new and distinct cultivar of hardy herbaceous Hibiscus hybrid plant named ‘Berrylicious’ comprising a winter-hardy perennial, naturally-compact, heavily branched stems, medium green leaves producing numerous mauve-lavender flowers with dark-raspberry eyes on nearly flat flowers over at least 12 weeks during the summer until frost. The new plant, Hibiscus ‘Berrylicious’ shows resistance to black spot fungus and resists deer browsing and the ruffled flowers resist wind and sun.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Berrylicious’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy, herbaceous, Hibiscus plant, Hibiscus ‘Berrylicious’ hybridized by Clarence H. Falstad in the summer of 2007 at a nursery in Zeeland, Mich. The new plant, originally labeled # 07-115-X, is from a cross between the proprietary hybrid # 05-21-01 (not patented) (female pod parent) times the proprietary hybrid # 04-18-06 (not patented) (male pollen parent). Both parents have a complex mixture of species in them, most likely including the species: moscheutos, coccineus and laevis. Hibiscus ‘Berrylicious’ has been propagated both by stem cuttings and tissue culture at the same nursery in Zeeland, Mich. The resultant plants have been found to be stable and true to type in successive generations of asexual reproduction.

BRIEF SUMMARY OF THE PLANT

Hibiscus ‘Berrylicious’ differs from its parents as well as all other Hibiscus known to the applicant in many traits. The foliage color of ‘Berrylicious’ is medium to light green with rare light burgundy tinting at the margin. The foliage shape of ‘Berrylicious’ is heterophyllous, depending on the time of year and position on the stem. Most leaves are dissected, mostly tri-lobed, rarely five-lobed with some either young leaves or those on immature plants being ovate. The flowers of ‘Berrylicious’ are nearly flat-faced with mauve lavender petals and deep-strawberry eyes. The most similar Hibiscus to ‘Berrylicious’ are Hibiscus ‘Fantasia’ U.S. Plant Pat. No. 11,853 and Hibiscus ‘Plum Crazy’ U.S. Plant Pat. No. 11,854. The new plant has greater branching habit than either ‘Fantasia’ or ‘Plum Crazy’. The flowers of ‘Berrylicious’ are larger, lighter lavender colored than ‘Plum Crazy’, and the foliage is lighter green with less burgundy tinting and more dissected than ‘Plum Crazy’. The flowers of ‘Fantasia’ are smaller, more reddish and more cupped than the new plant, and the pollen on the new plant is a clear, bright, yellow rather than the dirty, more gray-yellow of ‘Fantasia’. Foliage of the new plant is lighter green and more dissected than ‘Fantasia’.

In comparison to the parents, both #05-21-01 and #04-18-06 have reddish flowers. The new plant is also intermediate in plant height and flower size.

Hibiscus ‘Berrylicious’ is a unique hardy herbaceous hibiscus with the following combined traits:

• • 1. Winter-hardy, upright rounded habit with good branching.
  • 2. Many nearly flat-faced flowers with mauve lavender petals, shiny deep-strawberry eyes and contrasting, bright, clear-yellow pollen.
  • 3. Dissected foliage of medium to light green with reddish veins.

BRIEF DESCRIPTION OF THE DRAWINGS

The photograph of the new plant demonstrates 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 plant in the drawing is a two year-old plant grown in the full sun field in Ottawa County, Mich. with water and fertilizer applied as needed but no growth regulators.

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. The new plant, Hibiscus ‘Berrylicious’, 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 two-year old plants in the loamy-sand unshaded field trials of a nursery in Zeeland, Mich. and production field rows in Allegan County, Mich., respectively, both with supplemental fertilizer and water as needed. The plants are natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year.
