Botanical classification: Veronica spicata L.
Variety denomination: ‘Lavender Lightsaber’.
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. was on Feb. 1, 2018. The claimed plant was first sold on Jul. 9, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Veronica ‘Lavender Lightsaber’ 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 ‘Lavender Lightsaber’, and hereinafter referred to as the cultivar ‘Lavender Lightsaber’ or the “new plant”. The new plant was an insect pollination controlled by the inventor in the summer of 2013 in the hybridizing greenhouses of a wholesale perennial nursery in Zeeland, Mich., USA, with Veronica ‘Red Fox’ (not patented) as the female parent and the unreleased proprietary hybrid known only as 08-13-01 (not patented) as the male parent.
The new plant has been asexually propagated initially by 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 2015 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 ‘Lavender Lightsaber’ 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. Upright, narrow habit with stiff, tall, upright spikes above dense stems of medium green foliage.
2. Scapes with numerous flowers of soft lavender petals.
3. Freely-branched peduncles with long blooming season.
The closest comparison varieties known to the inventor are ‘Blue Skywalker’ U.S. Plant Pat. No. 29,406, ‘Eveline’ U.S. Plant Pat. No. 14,888, ‘Perfectly Picasso’ U.S. Plant Pat. No. 29,720, ‘Alllove’ U.S. Plant Pat. No. 21,478, ‘Sweet Lullaby’ U.S. Plant Pat. No. 23,611, ‘Blue Skywalker’ has a more bluish flower of similar height. ‘Eveline’ has deeper purplish-red flowers on smaller plants. ‘Sweet Lullaby’ has flowers that are slightly deeper lavender on much shorter stems. The flowers of ‘Alllove’ are intense red purple and the habit is much shorter than the new plant. ‘Red Fox’ has flowers that are bright fuchsia pink and the habit is shorter and less spreading. ‘Perfectly Picasso’ has flowers that are medium pink and the habit is broader and more rounded. The male parent 08-13-01 was taller and has flowers of soft lavender color.
BRIEF DESCRIPTION OF THE DRAWINGS
The photographs of the new plant demonstrate the overall appearance and unique traits of ‘Lavender Lightsaber’ 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 ‘Lavender Lightsaber’ are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. ‘Lavender Lightsaber’ 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 three-year-old and one-year-old plants grown in a full-sun trial garden of a nursery in Zeeland, Mich. with supplemental fertilizer and water as needed.
