plant named ‘TNVERVB’

Abstract

A new and distinct form of Veronica plant characterized by purple blue flowers in narrow spikes, a dense, compact, spreading habit, small, medium green leaves, excellent branching with flower spikes at end of every branch, excellent vigor, and good garden performance.

Description

Botanical denomination: Veronica hybrid.

Variety designation: ‘TNVERVB’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica, given the name, ‘TNVERVB’. Veronica is in the family Plantaginaceae (formerly Scrophulariaceae). This new cultivar was part of a planned breeding program for vigorous new Veronica using Veronica hybrid ‘TNVERA’ as the seed parent and an unknown Veronica spicata as the pollen parent.

Compared to the seed parent, Veronica hybrid ‘TNVERA’ (U.S. Plant Pat. No. 26,416), the new cultivar has a larger plant size, with purple blue flowers rather than warm pink.

Compared to Veronica spicata INSPIRE™ ‘Blue’, an unpatented plant, the new cultivar grows taller and wider and has darker purple blue flowers.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TNVERVB’. The new cultivar exhibits the following characteristics:

• • 1. purple blue flowers in narrow spikes,
  • 2. a dense, compact, spreading habit,
  • 3. small, medium green leaves,
  • 4. excellent branching with flower spikes at end of every branch,
  • 5. excellent vigor, and
  • 6. good garden performance.

The new variety has been reproduced only by asexual propagation (stem cuttings and micropropagation). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and micropropagation as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
