Veronica plant named ‘Baby Blue’

Abstract

A new and distinct cultivar of Veronica plant named ‘Baby Blue’, characterized by its upright plant habit, freely flowering habit; dark blue-colored flowers; and good garden performance.

Description

Botanical designation: Veronica austriaca×Veronica spicata.

Cultivar denomination: ‘Baby Blue’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica, botanically known as Veronica austriaca×Veronica spicata and hereinafter referred to by the name ‘Baby Blue’.

The new Veronica is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program is to create new Veronica cultivars with numerous attractive flowers and good garden performance.

The new Veronica originated from a cross-pollination of an unnamed proprietary selection of Veronica austriaca, not patented, as the female, or seed, parent with an unnamed proprietary selection of Veronica spicata, not patented, as the male, or pollen, parent. The new Veronica was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Hillegom, The Netherlands in June, 2004.

Asexual reproduction of the new cultivar by vegetative cuttings in a controlled greenhouse environment in Hillegom, The Netherlands, since 2006, has shown that the unique features of this new Veronica are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Veronica have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Baby Blue’. These characteristics in combination distinguish ‘Baby Blue’ as a new and distinct cultivar:

• • 1. Upright plant habit.
  • 2. Freely flowering habit.
  • 3. Dark blue-colored flowers.
  • 4. Good garden performance.

Plants of the new Veronica differ from plants of the parent selections primarily in plant height and flower color.

Plants of the new Veronica can be compared to plants of Veronica ‘Ulster Dwarf Blue’, not patented. In side-by-side comparisons conducted by the Inventor in Hillegom, The Netherlands, plants of the new Veronica differed from plants of ‘Ulster Dwarf Blue’ in the following characteristics:

• • 1. Plants of the new Veronica were slightly taller than plants of ‘Ulster Dwarf Blue’.
  • 2. Plants of the new Veronica were more freely flowering than plants of ‘Ulster Dwarf Blue’.
  • 3. Plants of the new Veronica had better postproduction longevity than plants of ‘Ulster Dwarf Blue’.

The photograph at the top of the second sheet is a close-up view of typical inflorescences of ‘Baby Blue’.

The photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘Baby Blue’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Hillegom, The Netherlands for two years.
