Abstract

A new and distinct cultivar of Lobularia plant named ‘Inlbuwikni’, characterized by its compact, outwardly spreading, mounding and semi-trailing plant habit; freely branching habit; relatively small leaves; freely and continuous flowering habit; relatively long flowering period; small white-colored flowers; and good garden performance.

Description

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

Cultivar denomination: ‘INLBUWIKNI’.

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 ‘Inlbuwikni’.

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 compact and semi-trailing Lobularia plants with numerous flowers.

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 Gensingen, Germany since June, 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 ‘Inlbuwikni’. These characteristics in combination distinguish ‘Inlbuwikni’ as a new and distinct Lobularia plant:

• • 1. Compact, outwardly spreading, mounding and semi-trailing plant habit.
  • 2. Freely branching habit.
  • 3. Relatively small leaves.
  • 4. Freely and continuous flowering habit.
  • 5. Relatively long flowering period.
  • 6. Small white-colored flowers.
  • 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 are more compact than and not as vigorous as plants of ‘Inlbusnopr’.
  • 2. Plants of the new Lobularia are not as trailing as plants of ‘Inlbusnopr’.
  • 3. Plants of the new Lobularia flower about ten days later than plants of ‘Inlbusnopr’.

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

Plants of the new Lobularia can be compared to (Lobularia canariensis×Lobularia maritima)×Lobularia maritima ‘Inlbublupr’, disclosed in U.S. Plant Pat. No. 24,516. In side-by-side comparisons, plants of the new Lobularia differed from plants of ‘Inlbublupr’ in the following characteristics:

• • 1. Plants of the new Lobularia were not as vigorous as plants of ‘Inlbublupr’.
  • 2. Flowers of plants of the new Lobularia were consistently white in color whereas flowers of plants of ‘Inlbublupr’ were white in color and with development or under conditions of high temperatures and/or light levels became light violet in color.

Plants of the new Lobularia can be compared to (Lobularia canariensis×Lobularia maritima)×Lobularia maritima ‘Inlbupripr’, not patented. In side-by-side comparisons, plants of the new Lobularia differed from plants of ‘Inlbupripr’ in the following characteristics:

• • 1. Plants of the new Lobularia were more vigorous than plants of ‘Inlbupripr’.
  • 2. Plants of the new Lobularia and ‘Inlbupripr’ differed in leaf color as plants of ‘Inlbupripr’ had green and yellow-variegated leaves.
  • 3. Plants of the new Lobularia and ‘Inlbupripr’ differed slightly in flower color as flowers of plants of ‘Inlbupripr’ were off-white in color.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in one-gallon containers an outdoor nursery in Bonsall, Calif. and under cultural practices typical of commercial Lobularia production. During the production of the plants, day temperatures ranged from 27° C. to 32° C., night temperatures ranged from 20° C. to 24° C. and light levels ranging from 6,000 to 8,000 foot-candles. Plants were pinched two times and were three months 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.
