plant named ‘AKIV98-01’

Abstract

A new and distinct cultivar of Verbena plant named ‘AKIV98-01’, characterized by its low and outwardly spreading plant habit; vigorous growth habit; freely branching habit; freely flowering habit; large coral red-colored flowers that are held above and beyond the foliage; and resistance to Powdery Mildew.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘AKIV98-01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘AKIV98-01’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Shiga, Japan. The objective of the breeding program is to create new freely flowering Verbena cultivars with large flowers and resistance to Powdery Mildew.

The new Verbena plant originated from a cross-pollination made by the Inventor on May 25, 2005 in Shiga, Japan of Verbena peruviana ‘Sunvivaro’, disclosed in U.S. Plant Pat. No. 13,724, as the female, or seed, parent with Verbena hybrida ‘USBENAL17’, disclosed in U.S. Plant Pat. No. 14,877, as the male, or pollen, parent. The new Verbena plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Shiga, Japan on Jun. 29, 2007.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled environment in Shiga, Japan since June, 2007 has shown that the unique features of this new Verbena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Verbena have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AKIV98-01’. These characteristics in combination distinguish ‘AKIV98-01’ as a new and distinct cultivar of Verbena:

• • 1. Low and outwardly spreading plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Large coral red-colored flowers that are held above and beyond the foliage.
  • 6. Resistant to Powdery Mildew.

Plants of the new Verbena can be compared to plants of the female parent, ‘Sunvivaro’. Plants of the new Verbena differ primarily from plants of ‘Sunvivaro’ in the following characteristics:

• • 1. Plants of the new Verbena are more upright than plants of ‘Sunvivaro’.
  • 2. Plants of the new Verbena have larger flowers than plants of ‘Sunvivaro’.

Plants of the new Verbena can be compared to plants of the male parent, ‘USBENAL17’. Plants of the new Verbena differ primarily from plants of ‘USBENAL17’ in the following characteristics:

• • 1. Plants of the new Verbena do not stretch as much as plants of ‘USBENAL17’.
  • 2. Flower petals of plants of the new Verbena are more oblong than and not as rounded as flower petals of plants of ‘USBENAL17’.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Lan Depink’, disclosed in U.S. Plant Pat. No. 15,741. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘Lan Depink’ in the following characteristics:

• • 1. Plants of the new Verbena were not as compact as plants of ‘Lan Depink’.
  • 2. Plants of the new Verbena had larger flowers than plants of ‘Lan Depink’.

Plants of the new Verbena can also be compared to plants of the Verbena hybrida ‘USBENAL5’, disclosed in U.S. Plant Pat. No. 14,851. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘USBENAL5’ in the following characteristics:

• • 1. Flowers petals of plants of the new Verbena were more oblong than and not as round as flower petals of plants of ‘USBENAL5’.
  • 2. Plants of the new Verbena and ‘USBENAL5’ differed in flower color as plants of ‘USBENAL5’ had purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the autumn in 12.5-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures ranged from 18° C. to 38° C., night temperatures ranged from 9° C. to 18° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were six weeks old when the photographs and description were taken.
