plant named ‘Perfectly Puzzling’

Abstract

A new cultivar of Phlox plant named, ‘Perfectly Puzzling’, that is characterized by its flowers that vary in color from near white to light to medium raspberry violet; the different color flowers can be evident on a plant at the same time, its petals that are non-overlapping, notched (bifid) and narrow resulting in a “starry” appearance that is unusual for a moss Phlox, its petals with medium to dark violet striae at the base, and its flowers that are smaller in size than most moss Phlox, however the flowers still cover the plants 100% at peak bloom.

Description

Botanical classification: Phlox hybrid.

Cultivar designation: ‘Perfectly Puzzling’.

BACKGROUND OF THE INVENTION

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

The new invention arose from an ongoing controlled breeding program by the Inventor in Glencoe, Ill. The objectives of the breeding program are to develop improved cultivars of interspecific hybrids of Phlox 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.

‘Perfectly Puzzling’ originated as a seedling that arose flow seed planted from open pollination of Phlox subulata ‘Ellie B’ (not patented) in May 2009. The seed parent was surrounded by numerous other cultivars and hybrids of Phlox. ‘Perfectly Puzzling’ was selected in April of 2012 as a single unique plant amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by shoot tip cuttings by the Inventor in June 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 ‘Perfectly Puzzling’ as a unique cultivar of Phlox.

• • 1. ‘Perfectly Puzzling’ exhibits flowers that vary in color from near white to light to medium raspberry violet; the different color flowers can be evident on a plant at the same time.
  • 2. ‘Perfectly Puzzling’ exhibits petals that are non-overlapping, notched (bifid) and narrow resulting in a “starry” appearance that is unusual for a moss Phlox.
  • 3. ‘Perfectly Puzzling’ exhibits petals with light to dark violet striae at the base.
  • 4. ‘Perfectly Puzzling’ exhibits flowers that are smaller in size than most moss Phlox, however the flowers still cover the plants 100% at peak bloom.

The female parent of ‘Perfectly Puzzling’, ‘Ellie B’, differs from ‘Perfectly Puzzling’ in having flowers that are all white in color and smaller in width, and petals that have no striae, and that are broader and overlap at their bases. ‘Perfectly Puzzling’ can also be compared to the Phlox cultivars ‘Snowflake’ (not patented) and ‘Snow Queen’ (not patented). ‘Snowflake’ and ‘Snow Queen’ are both similar to ‘Perfectly Puzzling’ in flower size and in having distinctly notched (bifid) petal tips. ‘Snowflake’ differs from ‘Perfectly Puzzling’ in having flower petals that are all white in color with no striae and visible anthers at the top of the corolla throat with conspicuous orange yellow pollen, which are buried in the corolla throat on ‘Perfectly Puzzling’ flowers. ‘Snow Queen’ differs from ‘Perfectly Puzzling’ in having flower petals that are all white in color with no striae and that are broader and overlap at their bases.
