plant named ‘Spike’

Abstract

A new, distinct Veronica plant as described and illustrated, characterized by the combination of longer stems, longer blue flower spikes, and cleaner foliage compared to the seed parent.

Description

Latin name: Veronica hybrid.

Cultivar name: ‘Spike’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Veronica plant named ‘Spike’ characterized by the combination of longer stems, longer blue flower spikes, and cleaner foliage compared to the seed parent. The new Veronica was raised as a seedling from open pollinated seed sown from the seed parent Veronica spicara nana, not patented, in Hebron, Ill. in 2009. The male, pollen parent is unknown and was selected as a chance seedling. The selection of the new plant was due to the combination of longer stems, longer blue flower spikes, and cleaner foliage compared to the seed parent. Initial asexual reproduction has taken place at a nursery in Hebron, Ill. since 2010 by means of division, and vegetative stem cuttings. Continued asexual propagation by division and vegetative stem cuttings since that time has shown that the unique features of the new Veronica plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Veronica plant named ‘Spike’ characterized by combination of longer stems, longer blue flower spikes, and cleaner foliage compared to the seed parent have been observed to be unique and stable. For purpose of comparison the new plant will be referred to as ‘Spike’.

Plants of ‘Spike’ can be compared to the seed parent plant of Veronica spicata nana, not patented. 1. The ‘Spike’ plant is taller growing to 40 cm while Veronica spicata nana grows to 20 cm. 2. The ‘Spike’ plant has longer inflorescence growing to 23 cm in length while Veronica spicata nana inflorescence grow to 10 cm in length.

Plants of ‘Spike’ can also be compared to another Veronica spicata ‘Glory’, U.S. Plant Pat. No. 18,932, patented. 1. The ‘Spike’ plant has longer inflorescence growing to 23 cm in length, while Veronica spicata ‘Glory’ inflorescence grow to 2-15 cm in length. 2. The ‘Spike’ plant has a flower color of RHS 99 B while Veronica spicata ‘Glory’ has a flower color of N 88 A to N 89 A.
