plant named ‘PPPHL0617’

- Amerinova Properties

A new and distinct Phlox cultivar named ‘PPPHL0617’ is disclosed, characterized by vigorous plant growth and early flowering, with blooms produced over a long period of time. Plants have a good resistance to powdery mildew and produce dark purple flowers. The new variety is a Phlox, normally produced as an outdoor ornamental plant for containers or gardens.

Description

Latin name of the genus and species: Phlox subulata×stolonifera.

Variety denomination: ‘PPPHL0617’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a result of a planned breeding program directed by the inventor, Ushio Sakazaki, a citizen of Japan. The seed parent is an unnamed, unpatented variety of Phlox subulata and the pollen parent is an unnamed, unpatented variety of Phlox stolonifera. The cross resulting in ‘PPPHL0617’ was made Apr. 12, 2005. The new variety was discovered Sep. 15, 2006, by the inventor in a non-commercial nursery in Higashiomi Shiga, Japan.

Asexual reproduction of the new cultivar ‘PPPHL0617’ by vegetative cuttings was first performed Sep. 20, 2006 at a non-commercial nursery in Higashiomi Shiga, Japan. Multiple generations have since been produced and have shown that the unique features of this cultivar are stable and reproduced true to type in successive generations. The new cultivar was first sold and made available to the public in April 2011.

SUMMARY OF THE INVENTION

The cultivar ‘PPPHL0617’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PPPHL0617’ These characteristics in combination distinguish ‘PPPHL0617’ as a new and distinct Phlox cultivar:

    • 1. More vigorous growth habit than Phlox subulata varieties.
    • 2. Early flowering.
    • 3. Long flowering period.
    • 4. Good resistance to powdery mildew.
    • 5. Deep purple flowers.

PARENT COMPARISON

Plants of the new cultivar ‘PPPHL0617’ are similar to plants of the seed parent, Phlox subulata, unnamed, in most horticultural characteristics, however, plants of the new cultivar ‘PPPHL0617’ produce flowers over a significantly longer period than the seed parent. ‘PPPHL0617’ has a dark purple colored flower, whereas the seed parent produces flowers that are pink. Additionally, plants of the new variety are much more vigorous, and produce larger flowers than the seed parent.

Plants of the new cultivar ‘PPPHL0617’ are similar to plants of the pollen parent Phlox stolonifera, unnamed, in most horticultural characteristics, however, plants of the new cultivar ‘PPPHL0617’ produce flowers over a significantly longer period than the pollen parent. ‘PPPHL0617’ has a dark purple colored flower, whereas the pollen parent produces flowers that are light blue. Additionally, the new variety has smaller foliage than the pollen parent.

COMMERCIAL COMPARISON

‘PPPHL0617’ can be compared to the commercial variety Phlox subulata ‘Emerald Blue’, unpatented. The two varieties are very similar in most horticultural characteristics, however, plants of ‘PPPHL0617’ produce larger flowers, and flowers throughout Spring and Summer, whereas ‘Emerald Blue’ flowers only during the Spring. Additionally, plants of ‘PPPHL0617’ are more mounding in growth habit compared to the flat, mat forming habit of ‘Emerald Blue’. Flower color also differs, as the new variety produces flowers that are dark purple and less blue in shade than ‘Emerald Blue’.

‘PPPHL0617’ can be compared to the commercial variety Phlox subulata ‘Emerald Cushion Blue’, unpatented. The two varieties are very similar in most horticultural characteristics, however, plants of ‘PPPHL0617’ produce larger flowers, and flowers throughout Spring and Summer, whereas ‘Emerald Cushion Blue’ flowers only during the Spring. Additionally, plants of ‘PPPHL0617’ are more mounding growth habit compared to the flat, mat forming habit of ‘Emerald Cushion Blue’. Flower color also differs, as the new variety produces flowers that are dark purple and less blue in shade than ‘Emerald Cushion Blue’.
