Abstract

A new and distinct cultivar of Bouvardia plant named ‘WNBVESRED24’ is disclosed, characterized by abundant, vivid, scarlet-red flowers. Plants are compact with good branching and habit. Good in-ground landscape performance with no lodging. The new cultivar is a Bouvardia, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Bouvardia hybrid.

Cultivar denomination: ‘WNBVESRED24’.

BACKGROUND OF THE INVENTION

The new Bouvardia cultivar is a product of a planned breeding program conducted by the inventor. The objective of the breeding program was to produce new Bouvardia cultivars with good landscape performance, strong branching and bloom coverage with some cut flower interest. The cross resulting in this new cultivar was made in September of 2015, at a research nursery in Bonsall, California.

The seed parent is an unnamed, unpatented variety of Bouvardia x domestica. The pollen parent is the unpatented, proprietary cultivar of Bouvardia hybrid referred to as ‘Bouvardia Texas #21’. The new cultivar was identified and selected as a potentially interesting selection in May of 2016 at the same nursery in Bonsall, California.

Asexual reproduction of the new cultivar ‘WNBVESRED24’ was first performed in May of 2016 in Bonsall, California, by tip cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations. Date of public disclosure was Jun. 27, 2023, occurring in Grand Haven, Michigan. This disclosure was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Jun. 27, 2023 and the filing of this application fall within the exception allowed under 102(b)(1).

SUMMARY OF THE INVENTION

The cultivar ‘WNBVESRED24’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘WNBVESRED24’. These characteristics in combination distinguish ‘WNBVESRED24’ as a new and distinct Bouvardia cultivar:

- 1. Abundant, vivid scarlet-red flowers.
- 2. Compact shrub with good branching and habit.
- 3. Good in-ground landscape performance with no lodging.

PARENT COMPARISONS

Plants of the new cultivar ‘WNBVESRED24’ are similar to the seed parent in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

- 1. Flower color of the new cultivar is scarlet-red, while the flower color of the seed parent is pink with a fuchsia eye.
- 2. The new cultivar is a compact shrub suitable for landscape use, while the seed parent is a very compact cut flower plant suitable for pot production only.
- 3. The new cultivar blooms continuously from spring to summer, while the seed parent produces a single flush of blooms suitable for cut flower production.
- 4. Flowers of the new cultivar have no fragrance, while flowers of the seed parent have a noticeable fragrance.

Plants of the new cultivar ‘WNBVESRED24’ are similar to the pollen parent in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

- 1. Flower color of the new cultivar is scarlet-red, while the flower color of the pollen parent is orange.
- 2. The new cultivar is a compact shrub with good branching and habit, while the pollen parent is a medium-sized shrub with thinner branching.
- 3. The new cultivar blooms heavily and continuously from spring to summer, with larger flower clusters. The pollen parent blooms lightly and continuously from spring to summer, with fewer flowers per cluster.

COMMERCIAL COMPARISON

Plants of ‘WNBVESRED24’ are similar in some horticultural characteristics to the cultivar Bouvardia ternifolia ‘Scarlet Hummer’, unpatented. The new cultivar, however, differs in the following:

- 1. Plants of the new cultivar are more compact/tight than plants of this comparator.
- 2. The new cultivar is more floriferous than this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘WNBVESRED24’ grown in a field at a commercial nursery in Grand Haven, Michigan. This plant is 3 to 4 years old.

FIG. 2 illustrates a closer view of the flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
