Lilac plant named ‘GARlisabzar’

Abstract

A new and distinct variety of lilac plant having an upright, compact, dense and rounded plant habit, dark colored buds compared to flowers, and having a very strong lilac scent, is disclosed.

Description

Genus and species: Syringa hybrida.

Denomination: ‘GARlisabzar’.

BACKGROUND

‘GARlisabzar’ is a new and distinct variety of lilac. ‘GARlisabzar’ originated from a controlled cross in May 2008 in Tipp City, Ohio between the commercial female parent ‘Josee’ (unpatented), and the commercial male parent, ‘Bailsugar’ (U.S. Plant Pat. No. 15,588).

The resulting seeds from the cross were collected and planted in Tipp City, Ohio. ‘GARlisabzar’ was selected in May 2012 from the population of seedlings in Tipp City, Ohio. ‘GARlisabzar’ was first asexually propagated in May 2013 in Tipp City, Ohio from two-node softwood cuttings rooted under mist at 25 to 27 degrees Celsius.

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

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, compact, dense and rounded plant habit;
  • 2. Dark colored buds compared to flowers; and
  • 3. Having a very strong lilac scent.

DETAILED DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘GARlisabzar’. The data which define these characteristics were collected outdoors in Tipp City, Ohio in May 2015 from a 4-year-old plant. 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.
