plant named ‘Purple Illusion’

Abstract

The new and distinct cultivar of ornamental spike speedwell plant, Veronica spicata ‘Purple Illusion’, with short habit, stiff, upright, branched, dense spikes rosy-purple flowers beginning in late spring and continuing for up to five weeks above deep green foliage. The new plant is useful in the landscape as a specimen, en masse, as a container plant or as a cut flower.

Description

Botanical classification: Veronica spicata L.;

Variety denomination: ‘Purple Illusion’;

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Dec. 1, 2018. Prior to that the claimed plant was first sold privately on Mar. 26, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Veronica ‘Purple Illusion’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of spike speedwell, botanically known as Veronica spicata ‘Purple Illusion’, and hereinafter referred to as the cultivar ‘Purple Illusion’ or the “new plant”. The new plant was cross by the inventor on Jun. 29, 2012 in the hybridizing greenhouses of a wholesale perennial nursery in Zeeland, Mich., USA. The female or seed parent was a proprietary unreleased hybrid known only by the breeder code 08-57-03 (not patented) and the male or pollen parent was ‘Enchanted Indigo’ U.S. Plant Pat. No. 26,603.

The new plant was assigned the breeder code of 12-30-4. ‘Purple Illusion’ has been asexually propagated initially division and later by basal cuttings and shoot tip tissue culture at the same nursery in the greenhouses in Zeeland, Mich., since the summer of 2014 with subsequent asexually propagated plants found to be identical to the original selection with all the same traits as the original seedling.

BRIEF SUMMARY OF THE PLANT

Veronica ‘Purple Illusion’ is unique from all other spike speedwell known to the inventor. Several other cultivars may have some similar traits, but this is the only variety known by the inventor to have the following characteristic combinations that establish the new plant as unique:

1. Compact short habit with stiff, upright spikes above dense stems of deep green foliage.

2. Scapes with numerous, dense flowers of rosy-purple petals.

3. Branched peduncles begin blooming in late spring and continue for at least five weeks into summer.

The closest comparison varieties known to the inventor are ‘Mona Lisa Smile’ U.S. Plant Pat. No. 30,477, ‘Purpleicious’ U.S. Plant Pat. No. 17,639, ‘Hocus Pocus’ U.S. Plant Pat. No. 23,853 and ‘Purple Explosion’ U.S. Plant Pat. No. 24,757. ‘Mona Lisa Smile’ is taller in habit and has a flower color that is a lighter rosy purple. ‘Purpleicious’ has flowers that are lighter violet-purple and the habit is taller. ‘Purple Explosion’ has flowers that are deep purple-pink on plants that are much taller than the new plant. ‘Hocus Pocus’ has similar habit and size, but the flowers are a vivid violet-purple, and flower induction does not require vernalization. The female parent, 08-57-03, is taller and the flower was a lighter shade of lavender purple. The male parent has darker royal purple flowers with a tighter habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance and unique traits of ‘Purple Illusion’ as a three-year-old plant grown in a full-sun trial garden in Zeeland, Mich. 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 Veronica ‘Purple Illusion’ are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. ‘Purple Illusion’ 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.
