plant named ‘MACANE001’

Abstract

A distinct new cultivar of Anemone plant named ‘MACANE001’, characterized by an exceptionally long flowering season, upright, vigorous, free flowering and perennial plant habit with large white flowers having bluish violet banding on the reverse of the sepals. The new cultivar is an Anemone typically suited for ornamental container and landscape use.

Description

Latin name of the genus and species: Anemone hybrid.

Variety denomination: ‘MACANE001’.

BACKGROUND OF THE INVENTION

The new Anemone was discovered by the inventors, Elizabeth and Alasdair MacGregor, as a chance seedling in a group of Anemone rupicola seedlings, growing in a protected poly tunnel greenhouse at a commercial nursery, in Kirkcudbright, Scotland, in 2001.

The seed had been collected from Anemone rupicola plants grown in a walled garden, in an area also containing Anemone hybrida and Anemone hupehensis cultivars (not patented). The very vigorous habit and exceptionally long flowering season of Anemone ‘MACANE001’ indicates that one of the aforementioned cultivars was the pollen parent, however the inventors are unable to confirm this.

Asexual reproduction by root cuttings has been undertaken in 2003, by the inventors in their own nursery in Kirkcudbright, Scotland. Plants produced have proved to be stable and reproduced true to type in successive generations. After several years experimentation in a commercial research laboratory in the Netherlands, tissue culture plants have also been produced and have also proved to be stable and true to type. Commercial production was not undertaken until tissue culture plantlets could be supplied to the market in Fall 2010.

SUMMARY OF THE INVENTION

The cultivar ‘MACANE001’ 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 ‘MACANE001’. These characteristics in combination distinguish ‘MACANE001’ as a new and distinct Anemone cultivar:

• • 1. Exceptionally long flowering season, typically in Scotland from the end of April until November in protected conditions and from early June until November outdoors.
  • 2. Large white flowers with distinctive bluish-violet banding on the reverse of the sepals.
  • 3. Vigorous, perennial garden performance

PARENTAL COMPARISON

Plants of the new cultivar ‘MACANE001’ are similar to the seed parent, Anemone rupicola in most horticultural characteristics. However, plants of ‘MACANE001’ differ in that they are larger and more vigorous, and more floriferous. Additionally, the new variety produces larger flowers, with more distinct coloration on the petal reverse. The flowering season for ‘MACANE001’ is longer, and flowering more consistent during the season than for Anemone rupicola.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘MACANE001’ are similar to the known commercial variety, Anemone hybrida ‘Honorine Jobert’ in some horticultural characteristics. However, plants of ‘MACANE001’ differ in that they are shorter, and more floriferous. Additionally, the new variety produces flowers with more distinct coloration on the petal reverse. The flowering season for ‘MACANE001’ begins at least 2 months earlier than ‘Honorine Jobert’.

Plants of the new cultivar ‘MACANE001’ are similar to the known commercial variety, Anemone multifida ‘Annabella White’ in some horticultural characteristics. However, plants of ‘MACANE001’ differ in that they are taller, more vigorous, and more floriferous. Additionally, the new variety produces larger flowers, with more distinct coloration on the petal reverse. The flowering season for ‘MACANE001’ begins at least 1 month earlier than ‘Annabelle White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plants of ‘MACANE001’ grown outdoors in a garden in Kirkcudbright, Scotland. This plant is approximately 15 months old.

FIG. 2 illustrates a close up of the flower, front and reverse. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
