plant named ‘Pink Potion’

Abstract

The new and distinct cultivar of hybrid ornamental spiked speedwell plant Veronica ‘Pink Potion’ with dense flower production of numerous self-cleaning pink flowers covering long, deep green foliage beginning in mid-summer and continuing until mid-fall when deadheaded. ‘Pink Potion’ is suitable for a potted plant, for the garden, and for cut flower arrangements.

Description

Botanical classification: Veronica hybrid.

Variety denomination: ‘Pink Potion’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of spiked speedwell, botanically known as Veronica hybrid, and hereinafter also referred to by the cultivar name ‘Pink Potion’ or “the new plant”. The new plant selected as a single seedling among a cross performed under direction of the inventor at a wholesale perennial nursery in Zeeland, Mich. of a proprietary unreleased seedling of ‘Purpleicious’ U.S. Plant Pat. No. 17,639 known by the breeder code 08-57-03 (not patented) times Veronica ‘Rotfuchs’ (not patented) (more commonly sold in the U.S. under the name ‘Red Fox’) on Jun. 29, 2012. The new plant was grown on in trials at the same nursery in Zeeland, Mich. and when passed the initial evaluation in early summer of 2013 was assigned the breeder code 12-31-01. The plant has been asexually propagated by basal shoot tip cuttings in the greenhouses at the same nursery in Zeeland, Mich., with subsequent asexually propagated plants found to be stable and identical to the original selection with all the same traits as the original seedling.

BRIEF SUMMARY OF THE PLANT

Veronica ‘Pink Potion’ is unique from all other spiked speedwell known to the inventor. Several other cultivars have blue to purple flowers, but this is the only variety known by the applicant to have the following trait combinations.

Compared to the female parent, 08-57-03, the new plant has flowers that are pink colored rather than purple and is shorter. Compared to the male parent ‘Rotfuchs’ the new plant has flowers of a pink rather than a deep fuchsia pink, is slightly taller and has more heavily-branched scapes.

The closest comparison varieties known to the inventor in flower color are Veronica ‘Tickled Pink’ U.S. Plant Pat. No. 16,182 and Veronica ‘Sweet Lullaby’ U.S. Plant Pat. No. 23,611. The new plant has cleaner, less mildew prone foliage than ‘Sweet Lullaby’ and slightly different flower color. Compared to ‘Tickled Pink’ the new plant is taller with slightly different pink flower color.

The following are traits of Veronica ‘Pink Potion’ that in combination distinguish it from all other spiked speedwell known to the inventor:

• • 1. Tall, well-branched scapes producing nearly continuous heavy flower show that covers the top of the plant.
  • 2. Numerous self-cleaning flowers of pink petals beginning in mid-summer.
  • 3. Lanceolate to oblanceolate foliage of deep green.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrates the overall appearance and unique traits of ‘Pink Potion’ as a two-year old plant grown in a full-sun trial garden in Zeeland, Mich. with supplemental water and fertilizer provided as needed. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references of ‘Pink Potion’ are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Veronica ‘Pink Potion’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are based on two-year old plants in the full-sun trial garden of a nursery in Zeeland, Mich. with supplemental fertilizer and water as needed.
