plant named ‘G13110’

Abstract

A new and distinct cultivar of Syringa plant, referred to by its cultivar name, ‘G13110’, is described. The new variety forms light pink-colored flowers which are strongly fragrant. Dark-green-colored foliage is formed, and the new variety is moderately vigorous and densely branched. The growth habit is compact. The new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Syringa hybrida.

Variety denomination: ‘G13110’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was July 2024, in Columbus, Ohio at the Cultivate Trade Show. The first offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Syringa plant botanically known as Syringa hybrida and hereinafter referred to by the cultivar name ‘G13110’.

The new cultivar originated in a controlled breeding program in Bellefonte, Pennsylvania during May 2009. The objective of the breeding program was the development of a series of Syringa cultivars with a faster production cycle, compact habits, and strong powdery mildew resistance.

The new cultivar was created by cross-pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new cultivar is Syringa x hyacinthiflora ‘Maidens Blush’ (not patented). The male parent (i.e., the pollen parent) of the new cultivar is a non-patented unnamed breeder seedling.

The parentage of the new variety can be summarized as follows:
‘Maidens Blush’ x unnamed breeder seedling

The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during May 2013 in a controlled environment in Bellefonte, Pennsylvania.

SUMMARY OF THE INVENTION

It was found that the new variety of Syringa plant of the present invention possesses the following combination of characteristics:

• • (a) forms light pink colored, strongly fragrant flowers,
  • (b) exhibits dark green-colored foliage, and
  • (c) displays a densely branched and compact growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘Maidens Blush’ variety (i.e., the seed parent) displays bicolor, pink-colored flowers, provides medium green-colored foliage, and exhibits a moderately vigorous compact growth habit, whereas the new variety displays lighter pink-colored flowers, provides darker green colored foliage, exhibits a more densely branching growth habit, and has an increased resistance to lilac powdery mildew compared to the seed parent. In addition, the unnamed breeder seedling male parent (i.e., the pollen parent) displays white colored flowers, provides medium green-colored foliage, and exhibits a moderately vigorous and somewhat sprawling growth habit, compared to the new variety that displays pink-colored flowers, provides a darker green colored foliage, and exhibits more upright and densely branching growth habit. Moreover, the new variety can be readily distinguished from related similar non-parental varieties. For example, the ‘Katherine Havemeyer’ variety (not patented) is the most similar commercially available cultivar and exhibits a less dense growth habit and decreased resistance to powdery mildew compared to the new variety.

The new variety has been found to undergo asexual propagation at Bellefonte, Pennsylvania by softwood cuttings. Asexual propagation by softwood cuttings at Bellefonte, Pennsylvania has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘G13110’. The Syringa plants of the new variety were grown in a field in Cochranville, Pennsylvania for approximately three years. Photographs were taken May 4, 2018.
