plant named ‘Balsashink’

Abstract

A new and distinct cultivar of Phlox plant named ‘Balsashink’, characterized by its upright to outwardly spreading and low mounding plant habit; moderately vigorous growth habit; dark green-colored leaves; freely flowering habit; relatively long flowering period; light reddish purple-colored flowers; and good container and garden performance.

Description

Botanical designation: Phlox hybrida (Phlox subulata X Phlox stolonifera).

Cultivar denomination: ‘BALSASHINK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox plant, commonly referred to as Woodland Phlox, botanically known as Phlox hybrida and hereinafter referred to by the name ‘Balsashink’.

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Hem, The Netherlands. The objective of the breeding program was to create new Phlox plants with a low mounding to spreading growth habit, numerous flowers and a long flowering time.

The new Phlox plant originated from a cross-pollination made by the Inventor in May 2016 in Hem, The Netherlands, of Phlox subulata ‘Amazing Grace’, not patented, as the female, or seed, parent with Phlox stolonifera ‘Home Fries’, not patented, as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Hem, The Netherlands in July 2017.

Asexual reproduction of the new Phlox plant by vegetative cuttings in a controlled environment in Hem, The Netherlands and West Chicago, Illinois since July 2017 has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘Balsashink’. These characteristics in combination distinguish ‘Balsashink’ as a new and distinct Phlox plant:

• • 1. Upright to outwardly spreading and low mounding plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Relatively long flowering period.
  • 6. Light reddish purple-colored flowers.
  • 7. Good container and garden performance.

Plants of the new Phlox differ primarily from plants of the female parent, ‘Amazing Grace’, in flower color as plants of the new Phlox have light reddish purple-colored flowers whereas plants of ‘Amazing Grace’ have white-colored flowers with red purple-colored centers. In addition, plants of the new Phlox are more mounding than plants of ‘Amazing Grace’.

Plants of the new Phlox differ primarily from plants of the male parent, ‘Home Fries’, in flower color as plants of the new Phlox have light reddish purple-colored flowers whereas plants of ‘Home Fries’ have pink-colored flowers. In addition, plants of the new Phlox are not as vigorous as plants of ‘Home Fries’.

Plants of the new Phlox can also be compared to plants of Phlox subulata ‘Emerald Pink’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Emerald Pink’ differ in the following characteristics:

• • 1. Plants of the new Phlox are more uniformly mounding than plants of ‘Emerald Pink’.
  • 2. Plants of the new Phlox and ‘Emerald Pink’ differ in flower color as plants of the new Phlox have light reddish purple- colored flowers whereas plants of ‘Emerald Pink’ have pink-colored flowers.
  • 3. Plants of the new Phlox flower for a longer period of time than plants of ‘Emerald Pink’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late winter and early spring in 10-cm containers in a polyethylene-covered greenhouse in Elburn, Illinois and under cultural practices typical of commercial Phlox production. Plants were three months old from planting rooted young plants when the photographs and the description were taken.
