Hibiscus plant named ‘Cherry Choco Latte’

Abstract

A new and distinct cultivar of winter-hardy, herbaceous, perennial, hybrid Hibiscus plant named Cherry Choco Latte comprising a compact slightly spreading habit of multiple, well-branched, basal stems having flowers over a long season with near white petals having sharply contrasting magenta veins and large deep red eye. The heavy substance petals have a fold on the leading edge and are slightly ruffled at the apex giving the flower the ability to withstand harsh winds and rains. The three to five-lobed, deeply-dissected foliage is mahogany colored when young or when exposed to high light intensity and becomes dark green with purple mahogany blushing when mature.

DETAILED BOTANICAL DESCRIPTION

(4) 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 Cherry Choco Latte, 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 a three-year-old plant 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 without treatment of plant growth regulators, nor pinching at any time in the growth year.
