Latin name of the genus and species:Bouvardia hybrida.

Variety denomination: ‘WINBUESLST’.

BACKGROUND OF THE INVENTION

The newBouvardiacultivar is a product of a planned breeding program conducted by the inventor. The objective of the breeding program was to produce new, floriferousBouvardiacultivars with dwarf plant forms, and vibrant flower colors. The cross resulting in this new variety was made in September of 2015, at a research nursery in Bonsall, Calif.

The seed parent is the unpatented, proprietary variety ofBouvardia hybridareferred to as ‘14BouB001-03’. The pollen parent is the unpatented, proprietary variety ofBouvardia ternifoliareferred to as ‘BouvardiaTexas #17’. The new variety was identified and selected as a potentially interesting selection in the Summer of 2016. Selection was made at the same nursery in Bonsall, Calif.

Asexual reproduction of the new cultivar ‘WINBUESLST’ was first performed in August 2016 in Bonsall, Calif., by tip cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘WINBUESLST’ 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 ‘WINBUESLST’. These characteristics in combination distinguish ‘WINBUESLST’ as a new and distinctBouvardiacultivar:1. Rounded/globose plant form.2. Bright red-orange flower color3. Reblooming, self-cleaning flowering.4. Compact and dwarf growth habit.

PARENT COMPARISONS

Plants of the new cultivar ‘WINBUESLST’ are similar to the seed parent in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:1. The new variety has orange-red flowers, while the seed parent has light pink/coral flowers.2. Flowers of the new variety have a shorter floral tube than flowers of the seed parent.3. The new variety produces smaller leaves than the seed parent.

Plants of the new cultivar ‘WINBUESLST’ are similar to the pollen parent in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:1. The new variety has a rounded/globose growth habit; the pollen parent has an upright plant habit.2. The new variety has larger leaves than the pollen parent.

COMMERCIAL COMPARISON

Plants of ‘WINBUESLST’ are similar in some horticultural characteristics to the varietyBouvardia ternifolia‘Scarlet Hummer’, unpatented. The new variety, however, differs in the following:1. Flowers of ‘WINBUESLST’ have a different color throat than petals. Flowers of ‘Scarlet Hummer’ are a single color.2. Flowers of ‘WINBUESLST’ are more orange-red; flowers of ‘Scarlet Hummer’ are red.
