Helianthus plant named `TMSNBLEV16-1`
Abstract
A Helianthus plant named `TMSNBLEV16-1` is disclosed,
characterized by a distinctive compact basalt, multi-branching
habit. Plants tolerate heat well and can are suitable for
vegetative propagation. The flowering period is exceptionally long,
from around early Spring until mid to late Fall. Flowers are yellow
with a brown center, medium-sized and fully sterile. The new plant
is useful for outdoor ornamental purposes, normally produced as an
outdoor garden or container plant.

Claims
What is claimed is:
1. A new and distinct variety of Helianthus plant named
`TMSNBLEV16-1` as described and shown herein.
Description
Genus and species: Helianthus x hybridus.
Variety denomination: `TMSNBLEV16-1`.
BACKGROUND OF THE INVENTION
`TMSNBLEV16-1` is a product of a breeding and selection program for
ornamental Helianthus varieties which can be vegetatively
propagated. The new plant of the present invention comprises a new
and distinct cultivar of Helianthus plant.
`TMSNBLEV16-1` is a seedling resulting from the crossing of the
seed parent, an unpatented proprietary Helianthus hybridus referred
to as `HE15015` with the pollen parent, an unnamed, unpatented
proprietary Helianthus hybridus. The crossing resulting in this new
variety was conducted in July 2016 in Ipswich, UK. The selection of
the new variety was made in July 2016, by the inventor at a
research nursery located in Ipswich, UK.
`TMSNBLEV16-1` was first asexually reproduced by terminal
vegetative cuttings at a greenhouse in Ipswich, UK, August 2016.
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) yellow
inflorescence. 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 `TMSNBLEV16-1` 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 dwarf and erect.
Plants of the new cultivar `TMSNBLEV16-1` 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 smaller inflorescence than the new variety.
COMPARISON WITH COMMERCIAL CULTIVARS
`TMSNBLEV16-1` 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,
`TMSNBLEV16-1` differs in the following: 1. Inflorescences of the
new variety are medium-sized, inflorescences of this comparator
large. 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.
Plants of the new variety tolerate heat better than plants of this
comparator.
`TMSNBLEV16-1` can be compared to the commercial variety `Table
Mountain`, unpatented. Plants of the two varieties are similar in
most horticultural characteristics, however, `TMSNBLEV16-1` differs
in the following: 1. Inflorescences of the new variety are
medium-sized, inflorescences of this comparator are small. 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 several plants of the new variety at
approximately 8 months of age.
FIG. 2 illustrates a single of the new variety at approximately 8
months of age.
FIG. 3 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 Visalia, Calif. under
natural light, natural day length and temperatures. Measurements
were taken during April. Plants were grown and measured in a
1-gallon pot at approximately 8 months of age.
The following is a description of the plant and characteristics
that distinguish `TMSNBLEV16-1` 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 Colour Chart, edition 2007.
