Abstract

A Helianthus plant named ‘TMSNBLEV01’ is disclosed, characterized by bright yellow fully double flowers composed of only ray florets. Plants have an attractive spreading habit and flower prolifically. The flowering period is exceptionally long, from around early Spring until mid to late Fall. Plants are useful for outdoor ornamental purposes, normally produced as an outdoor garden or container plant.

Description

Genus and species: Helianthus x hybridus.
Variety denomination: ‘TMSNBLEV01’.
BACKGROUND OF THE INVENTION
‘TMSNBLEV01’ is a product of a breeding and selection program for ornamental Helianthus varieties to be vegetatively propagated. The new plant of the present invention comprises a new and distinct cultivar of Helianthus plant.
‘TMSNBLEV01’ is a seedling resulting from the crossing of the seed parent, an unpatented proprietary Helianthus hybridus referred to as ‘HE13026’ with the pollen parent, an unpatented proprietary Helianthus hybridus referred to as ‘HE13002’. The crossing resulting in this new variety was conducted in July 2014 in Suffolk, UK. The selection of the new variety was made in July 2015, by the inventor at a research greenhouse located in Suffolk, UK.
‘TMSNBLEV01’ was first asexually reproduced by terminal vegetative cuttings at a greenhouse in Suffolk UK, August 2015 and has been asexually reproduced over an approximately three-year period. The new cultivar has been found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Suffolk, UK:
  • 1. Compact basal multi-branching habit.
  • 2. Medium sized (12 cm) bi-color inflorescence colored yellow with a brown center.
  • 3. Exceptionally long continuous blooming. Non-stop blooming May to first frosts, due to day length neutral quality.
  • 4. Sterile flowers.
  • 5. Heat tolerant.
  • 6. Suitability for vegetative propagation
COMPARISON WITH PARENT VARIETIES
Plants of the new cultivar ‘TMSNBLEV01’ are similar to plants of the seed parent in most horticultural characteristics. The new variety however, differs in the following:
  • 1. Blooming period of the new variety is May until first frost, the seed parent blooming period is July and August.
  • 2. The new variety is totally sterile, the seed parent is pollenless but seed fertile.
  • 3. The seed parent does not tolerate heat as well as the new variety.
  • 4. Plants of the new variety are compact with multiple branches, plants of the seed parent are erect.
Plants of the new cultivar ‘TMSNBLEV01’ are similar to plants of the pollen parent in most horticultural characteristics. The new variety however, differs in the following:
  • 1. Blooming period of the new variety is May until first frost, the pollen parent blooming period is June to October.
  • 2. The new variety is totally sterile, the pollen parent is fully fertile.
  • 3. The pollen parent has small entirely yellow inflorescence, the new variety has medium sized bi-color inflorescence.
  • 4. Plants of the new variety are compact with multiple branches, plants of the seed parent are erect.
COMPARISON WITH COMMERCIAL CULTIVARS
‘TMSNBLEV01’ can be compared to the commercial variety ‘Double Whammy’, U.S. Plant Pat. No. 25,494. Plants of the two varieties are similar in most horticultural characteristics, however, ‘TMSNBLEV01’ differs in the following:
  • 1. Flowers of the new variety are medium sized and bi-color, flowers of this comparator are a single golden yellow color.
  • 2. Blooming period of the new variety is May until first frost, the blooming period of this comparator is August to October.
  • 3. Plants of the new variety are well branched and compact, plants of this comparator are tall and upright.
  • 4. Flowers of the new variety are single, flowers of this comparator are double.
  • 5. Flowers of the new variety are fully sterile, flowers of this comparator are fully fertile.
‘TMSNBLEV01’ can be compared to the commercial variety ‘Table Mountain’, (U.S. 2007/0050874—abandoned). Plants of the two varieties are similar in most horticultural characteristics, however, ‘TMSNBLEV01’ differs in the following:
  • 1. Flowers of the new variety are medium sized and bi-color, flowers of this comparator are small and a single deep yellow color.
  • 2. Blooming period of the new variety is May until first frost, the blooming period of this comparator is August to September.
  • 3. Plants of the new variety are well branched and compact, plants of this comparator are upright.
  • 4. Flowers of the new variety are fully sterile, flowers of this comparator are fully fertile.
DESCRIPTION OF THE PHOTOGRAPHS
The present invention of a new and distinct variety of Helianthus is shown in the accompanying photographs, the colors being as nearly true as possible with color photographs of this type.
FIG. 1 illustrates a plant of approximately 6 months in a 1 gallon pot
FIG. 2 illustrates a close up of the inflorescence.
DESCRIPTION OF THE INVENTION
This new variety of Helianthus is of the botanical classification Helianthus hybridus. The observations and measurements were gathered from plants grown outdoors in San Juan Bautista, Calif. under natural light, natural day length and temperatures. Measurements were taken during April.
The following is a description of the plant and characteristics that distinguish ‘TMSNBLEV01’ as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is The Royal Horticultural Society color chart, edition 2007.
