<i>Hibiscus </i>plant named ‘G21087’

Abstract

A new and distinct cultivar of Hibiscus moscheutos plant named G21087 is disclosed, characterized by large light pink flowers with distinct dark veins radiating from the central eye out into the petals. Flower size is large, about 7 to 8 inches. Young foliage is deep purple, and a deep purple flush is maintained on mature foliage. Plants are compact, growing to approximately 36 to 42 inches high and wide with dense basal branching. Plants emerge and flower earlier than is typical of the species. Plants have been shown Winter hardy to USDA Zone 5. The new variety is a Hibiscus moscheutos, normally produced as an outdoor garden or container plant.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates a 16-month old flowering plant in Summer (August).

(2) FIG. 2. is a close-up view of a typical flower of G21087.

(3) The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

(4) In the following description, color references are made to The Royal Horticultural Society Color Chart 2015, except where general terms of ordinary dictionary significance are used.
