Lavender plant named ‘Toscane’

Abstract

A new and distinct cultivar of Lavender plant named ‘Toscane’, characterized by its compact, upright, somewhat outwardly spreading and mounded plant habit; freely branching habit; dense and bushy plant form; early and freely flowering habit; large flowering period; and purple-colored flowers with light violet-colored terminal flower bracts.

Description

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘Toscane’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula stoechas, and hereinafter referred to by the name ‘Toscane’.

The new Lavender is a product of a planned breeding program conducted by the Inventor in Sappemeer, The Netherlands. The objective of the breeding program was to create new Lavender cultivars that flowered early, attractive flowers and good garden performance.

The new Lavender originated from a cross-pollination made by the Inventor in May, 2000, of the Lavandula stoechas cultivar Fat Head, not patented, as the female, or seed, parent with a proprietary selection of Lavandula stoechas identified as NA-20, not patented, as the male, or pollen, parent. The new Lavender was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Sappemeer, The Netherlands.

Asexual reproduction of the new cultivar by terminal cuttings at Sappemeer, The Netherlands, since 2002, has shown that the unique features of this new Lavender are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Toscane have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Toscane’. These characteristics in combination distinguish ‘Toscane’ as a new and distinct cultivar:

• • 1. Compact, upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Freely branching habit, dense and bushy plant form.
  • 3. Early and freely flowering habit.
  • 4. Long flowering period.
  • 5. Purple-colored flowers with light violet-colored terminal flower bracts.

Plants of the new Lavender can be compared to plants of the female parent, the cultivar Fat Head. Plants of the new Lavender differ from plants of the cultivar Fat Head in the following characteristics:

• • 1. Plants of the new Lavender flower about three weeks earlier than plants of the cultivar Fat Head.
  • 2. Plants of the new Lavender are more freely flowering than plants of the cultivar Fat Head.
  • 3. Plants of the new Lavender and the cultivar Fat Head differ in flower coloration.

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

• • 1. Plants of the new Lavender and the male parent selection differ in foliage coloration.
  • 2. Plants of the new Lavender and the male parent selection differ in flower coloration.

Plants of the new Lavender can be compared to plants of the Lavender cultivar Alexandra, not patented. In side-by-side comparisons conducted in Sappemeer, The Netherlands, plants of the new Lavender differed from plants of the cultivar Alexandra in the following characteristics:

• • 1. Plants of the new Lavender were more compact and denser than plants of the cultivar Alexandra.
  • 2. Plants of the new Lavender flowered earlier than plants of the cultivar Alexandra.
  • 3. Plants of the new Lavender had more rounded inflorescences than plants of the cultivar Alexandra.

Plants of the new Lavender can also be compared to plants of the Lavender cultivar Anouk, disclosed in U.S. Plant patent application Ser. No. 11/113,371. In side-by-side comparisons conducted in Sappemeer, The Netherlands, plants of the new Lavender differed from plants of the cultivar Anouk in the following characteristics:

• • 1. Plants of the new Lavender were more compact than and not as upright as plants of the cultivar Anouk.
  • 2. Plants of the new Lavender flowered earlier than plants of the cultivar Anouk.
  • 3. Plants of the new Lavender had more rounded inflorescences than plants of the cultivar Anouk.
