plant named ‘Lanconnecticut’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Lanconnecticut’, characterized by its broadly upright to trailing plant habit; moderately vigorous growth habit; freely branching habit; glossy dark green-colored leaves; early and freely flowering habit; and bright yellow-colored flowers with yellow orange-colored throats.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘LANCONNECTICUT’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla sanderi and hereinafter referred to by the name ‘Lanconnecticut’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Motril, Spain. The objective of the breeding program is to create new vigorous and freely branching Mandevilla plants with numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Motril, Spain in 2016 of a proprietary selection of Mandevilla sanderi identified as code number 09-0318-009-EE, not patented, as the female, or seed, parent with a proprietary selection of Mandevilla sanderi identified as code number 10-0054-032-EE, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Motril, Spain in June, 2017.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Motril, Spain, since October, 2017 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Lanconnecticut’. These characteristics in combination distinguish ‘Lanconnecticut’ as a new and distinct Mandevilla plant:

• • 1. Broadly upright to trailing plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Glossy dark green-colored leaves.
  • 5. Early and freely flowering habit.
  • 6. Bright yellow-colored flowers with yellow orange-colored throats.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Mandevilla are more freely branching than plants of the female parent selection.
  • 2. Leaves of plants of the new Mandevilla are more pointed than and not as round as leaves of plants of the female parent selection.
  • 3. Plants of the new Mandevilla have smaller flowers than plants of the female parent selection.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Mandevilla do not require high temperatures for rooting whereas plants of the male parent selection require high temperatures for rooting.
  • 2. Developed flowers of plants of the new Mandevilla face outwardly to slightly upright whereas developed flowers of the male parent selection face downward.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Lancalifornia’, disclosed in U.S. Plant Pat. No. 24,074. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Lancalifornia’ in the following characteristics:

• • 1. Plants of the new Mandevilla are more vigorous than plants of ‘Lancalifornia’.
  • 2. Plants of the new Mandevilla are more freely branching than plants of ‘Lancalifornia’.
  • 3. Plants of the new Mandevilla are more freely flowering than plants of ‘Lancalifornia’.
  • 4. Plants of the new Mandevilla do not require high temperatures for rooting and growth whereas plants of ‘Lancalifornia’ require high temperatures for rooting and growth.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.

The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical flowering plant of ‘Lanconnecticut’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical open flower of ‘Lanconnecticut’.

DETAILED BOTANICAL DESCRIPTION
