plant named ‘Inlbublupr’

Abstract

A new and distinct cultivar of Lobularia plant named ‘Inlbublupr’, characterized by its outwardly spreading, mounding and trailing to decumbent plant habit; freely branching habit; vigorous growth habit; relatively long leaves; freely and continuous flowering habit; relatively long flowering period; white-colored small flowers that with development become light violet in color; and tolerance to high temperatures.

Description

Botanical designation: (Lobularia canariensis×Lobularia maritima)×Lobularia maritima.

Cultivar denomination: ‘INLBUBLUPR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lobularia plant, botanically known as (Lobularia canariensis×Lobularia maritima)×Lobularia maritima and hereinafter referred to by the name ‘Inlbublupr’.

The new Lobularia plant is a product of a planned breeding program conducted by the Inventor in La Palma, Canary Islands, Spain. The objective of the breeding program was to develop new Lobularia plants with unique and attractive flower coloration.

The new Lobularia plant originated from a cross-pollination conducted by the Inventor in March, 2009 in La Palma, Canary Islands, Spain of a Lobularia canariensis×Lobularia maritima ‘Inlbusnopr’, disclosed in U.S. Plant Pat. No. 21,594, as the female, or seed, parent, with an unnamed selection of Lobularia maritima, not patented, as the male, or pollen, parent. The new Lobularia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in La Palma, Canary Islands, Spain in May, 2010. Asexual reproduction of the new Lobularia plant by vegetative cuttings in a controlled greenhouse environment in La Palma, Canary Islands, Spain since November, 2010 has shown that the unique features of this new Lobularia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lobularia have not been observed under all possible 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 ‘Inlbublupr’. These characteristics in combination distinguish ‘Inlbublupr’ as a new and distinct Lobularia plant:

• • 1. Outwardly spreading, mounding and trailing to decumbent plant habit.
  • 2. Freely branching and vigorous growth habit.
  • 3. Relatively long leaves.
  • 4. Freely and continuous flowering habit.
  • 5. Relatively long flowering period.
  • 6. White-colored small flowers that with development become light violet in color.
  • 7. Good garden performance and tolerant to high temperatures.

Plants of the new Lobularia differ from plants of the female parent, ‘Inlbusnopr’, in the following characteristics:

• • 1. Plants of the new Lobularia and ‘Inlbusnopr’ differ in stem and leaf color.
  • 2. Plants of the new Lobularia have smaller flowers than plants of ‘Inlbusnopr’.
  • 3. Plants of the new Lobularia and ‘Inlbusnopr’ differ in flower color as plants of ‘Inlbusnopr’ have white-colored flowers.

Plants of the new Lobularia differ from plants of the male parent selection primarily in leaf size as plants of the new Lobularia have longer leaves than plants of the male parent selection.

Plants of the new Lobularia can be compared to unnamed selections plants of seed-produced Lobularia maritima, not patented. In side-by-side comparisons, plants of the new Lobularia differed from plants of unnamed selections of seed-produced Lobularia maritima in the following characteristics:

• • 1. Plants of the new Lobularia were larger and more vigorous than plants of unnamed selections of seed-produced Lobularia maritima.
  • 2. Plants of the new Lobularia were more high temperature tolerant than plants of unnamed selections of seed-produced Lobularia maritima.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Lobularia 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 colors of the new Lobularia plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Inlbublupr’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Inlbublupr’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in one-gallon containers an outdoor nursery in Bonsall, Calif. under commercial practices typical of commercial Lobularia production. During the production of the plants, day temperatures ranged from 20° C. to 29° C. and night temperatures ranged from 14° C. to 18° C. Plants were pinched one time at planting and were six weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
