USPP16349P3 - Lilac plant named ‘Bailming’ - Google Patents

Abstract

A new and distinct highly ornamental cultivar of Syringa meyeri×Syringa microphylla is provided. A Lilac plant having a rounded uniform compact growth habit is described. Highly attractive trusses of fragrant red purple blossoms are formed in late spring that fade to lavender pink. The plant has good winter hardiness and has been found to be relatively free of insect and disease problems during observations to date. The plant is particularly well-suited for growing as an ornamental specimen or as a mass planting in the landscape.

Description

Botanical commercial classification: Syringa meyeri×Syringa microphylla/Ornamental Lilac Shrub.

Varietal denomination: cv. ‘Bailming’.

SUMMARY OF THE INVENTION

The new Lilac plant of the present invention was created at Harwood, N. Dak., U.S.A., by the cross of Syringa meyeri ‘Palibin’ (non-patented in the United States) and Syringa microphylla ‘Superba’ (non-patented in the United States). The parentage can be summarized as follows:
‘Palibin’בSuperba’.
Seeds from the cross were collected during 1976, were planted, and the resulting plants were observed. A single plant of new cultivar was selected during 1985 in view of its distinctive combination of ornamental characteristics. This plant initially was designated No. 92-1.

It was found that the cultivar of Syringa meyeri×Syringa microphylla exhibits the following combination of characteristics:

• • (a) exhibits a rounded uniform compact growth habit,
  • (b) forms attractive trusses of fragrant red purple blossoms in late spring that fade to lavender pink,
  • (c) is relatively free of insect and disease problems, and
  • (d) is well-suited for growing as a distinctive ornamental shrub in the landscape.

The new cultivar of the present invention provides a distinctive red purple blossom coloration to the landscape that is displayed in late spring after many other shrubs have finished flowering. It can be grown to advantage as a specimen shrub or in a mass planting. The plant is versatile for many uses in the landscape including foundation plantings and informal hedges. The superior hardiness of the Syringa meyeri ‘Palibin’ parent which generally is lacking in the Syringa microphylla ‘Superba’ parent is imparted to the new cultivar of the present invention.

The new cultivar of the present invention can be readily distinguished from its parental cultivars. More specifically, the ‘Palibin’ cultivar exhibits a low spreading growth habit and the blossoms open to a pale lilac coloration, and the ‘Superba’ cultivar exhibits a taller and considerably more spreading growth habit and forms deep pink blossoms.

The new cultivar of the present invention also can be readily distinguished from other Lilac cultivars, such as ‘Bailbelle’ (U.S. Plant Pat. No. 12,294), ‘Baildust’ (U.S. Plant Pat. No. 15,152), and ‘Bailsugar’ (U.S. Plant Pat. No. 15,588), resulting from the same breeding program in view of the distinctive blossom coloration. More specifically, the ‘Bailbelle’ variety forms pink blossoms, the ‘Baildust’ variety forms pale antique pink blossoms, and the ‘Bailsugar’ variety forms purple lilac blossoms. The red purple blossoms of the new variety fade to an attractive lavender pink.

The new cultivar of the present invention was asexually propagated by the use of rooted cuttings and grafting at St. Paul, Minn., U.S.A., during 1992, and the progeny were field planted during 1993. The distinctive characteristics of the new cultivar have been found to be stable and to be capable of transmission from one generation to another following such asexual propagation at St. Paul, Minn. and elsewhere. The new cultivar reproduces true to type in successive generations of asexual reproduction.

The new cultivar of the present invention also has been grafted on Syringa reticulata to form distinctive small grafted trees.

The new cultivar of the present invention has been named ‘Bailming’. It is a member of the FAIRYTALE™ Series of Lilac plants that includes the ‘Bailbelle’ ‘Baildust’ and ‘Bailsugar’ cultivars, and is being marketed under the PRINCE CHARMING trademark.

DETAILED DESCRIPTION

The chart used in the identification of colors is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. Common terms are to be accorded their ordinary dictionary significance. The description is based upon the observation during July 2002 and 2003 of five year-old plants propagated by the use of rooted cuttings and growing in containers and in the field at St. Paul, Minn., U.S.A.
