USPP31834P2 - Crape myrtle plant named ‘GARzarnobemagen’ - Google Patents

Abstract

A new and distinct variety of crape myrtle plant, an upright, and compact shrub having numerous flowers on panicles and resistance to leaf spot and powdery mildew strains found in Ohio and California, is disclosed.

Description

Genus and species: Lagerstroemia indica.

Denomination: ‘GARzarnobemagen’.

BACKGROUND

‘GARzarnobemagen’ is a new and distinct variety of crape myrtle. ‘GARzarnobemagen’ originated from a controlled cross in August 2011 in Tipp City, Ohio between the female parent, an unnamed and unpatented seedling derived from the cross between the crape myrtle plants ‘Centennial’ (unpatented) and ‘Dynamite’ (U.S. Plant Pat. No. 10,269) and the male parent, ‘Tightwad Red’ (U.S. Plant Pat. No. 14,975).

The resulting seeds from the cross were collected in August 2011 and planted and evaluated in Tipp City, Ohio. ‘GARzarnobemagen’ was selected in July 2012 from the population of seedlings in Tipp City, Ohio. ‘GARzarnobemagen’ was first asexually propagated in July 2014 in Tipp City, Ohio from softwood cuttings.

Other subsequent asexual propagations were conducted in controlled environments in Tipp City, Ohio and demonstrate that ‘GARzarnobemagen’ reproduces true to type in successive generations of asexual reproduction via softwood cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Tipp City, Ohio.

• • 1. An upright, and compact shrub having numerous flowers on panicles; and
  • 2. Resistance to leaf spot and powdery mildew strains found in Ohio and California.

DETAILED DESCRIPTION

The following detailed descriptions set for the distinctive characteristics of ‘GARzarnobemagen’. The data which define these characteristics were collected outdoors in Tipp City, Ohio. Plants were propagated in a greenhouse in 2014 and transplanted to an outdoor field in Tipp City, Ohio in May 2015 and evaluated each year thereafter. The phenotype of this new variety will vary somewhat with variation in environmental, climatic, and cultural conditions as it has not been tested in other environments.
