USPP28737P2 - Phlox plant named ‘Early Bird’ - Google Patents

Abstract

A new cultivar of Phlox plant named, ‘Early Bird’, that is characterized by its early bloom period that begins in mid-April, peaks in late April, and lasts four to five weeks, its large, overlapping, conspicuous striae that are deep purplish red in color, its flowers that are deep purplish pink in color, and its flowers that cover 100% of the plant at peak bloom.

Description

Botanical classification: Phlox hybrid.

Cultivar designation: ‘Early Bird’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox ‘Early Bird’ and will be referred to hereafter by its cultivar name, ‘Early Bird’. The new cultivar represents a new moss phlox, a herbaceous perennial grown for landscape use.

The new invention arose from an ongoing controlled breeding program conducted by the Inventor in Glencoe, Ill. The objectives of the breeding program are to develop improved cultivars of interspecific Phlox hybrids with novel ornamental traits such as unique flower colors, plant habits, flower fragrance and adaptability to garden conditions in the upper Midwest (U.S.D.A. Zone 5) and similar climates.

‘Early Bird’ was discovered by the Inventor as a chance seedling growing in his nursery in March of 2012. The new cultivar was found growing in a trial garden located nearby 17 proprietary unnamed cultivars of Phlox, thus the exact parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by shoot tip cuttings by the Inventor in May of 2012 in Glencoe, Ill. Asexual propagation by shoot tip cuttings has determined that the characteristics of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Early Bird’ as a unique cultivar of Phlox.

• • 1. ‘Early Bird’ exhibits an early bloom period that begins in mid-April, peaks in late April, and lasts four to five weeks.
  • 2. ‘Early Bird’ exhibits petals with large, overlapping, conspicuous striae that are deep purplish red in color.
  • 3. ‘Early Bird’ exhibits flowers that are deep purplish pink in color.
  • 4. ‘Early Bird’ exhibits flowers that cover 100% of the plant at peak bloom.

‘Early Bird’ can be most closely compared to the Phlox subulata cultivars ‘Crimson Beauty’ (not patented) and ‘Scarlet Flame’ (not patented). ‘Crimson Beauty’ is similar to ‘Early Bird’ in flower color and in having conspicuous deep purplish red petal striae. ‘Crimson Beauty’ differs from ‘Early Bird’ in having a later commencing bloom period, in having petal striae that are smaller in size and not overlapping, and in having foliage that is larger in size. ‘Scarlet Flame’ is similar to ‘Early Bird’ in having conspicuous deep purplish red petal striae. ‘Scarlet Flame’ differs from ‘Early Bird’ in having a later commencing bloom period, in having flowers with irregularly shaped petals, in having flowers that are smaller in size, in having a more vigorous growth rate, and in having a less uniform growth habit that is both upright and spreading.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Phlox. The photographs were taken of three year-old plants of ‘Early Bird’ as grown outdoors in a trail garden in Glencoe, Ill.

The photograph in FIG. 1 provides a top view of ‘Early Bird’ illustrating the plant in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Early Bird’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Phlox.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
