I claim:
1. A new and distinct Heuchera plant as herein illustrated and
described.
Description
Botanical denomination: Heuchera hybrid.
Variety designation: `Dark `N` Bright`.
Trademark designation: SIRENS' SONG.TM. `Dark `N` Bright`.
Cross reference to Heuchera `Dark Night`, applied for concurrently
having application Ser. No. 16/501,733.
Cross reference to Heuchera `Orange Delight`, applied for
concurrently having application Ser. No. 16/501,732.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Heuchera given the cultivar name of `Dark `N` Bright`. Heuchera is
in the family Saxifragaceae. Heuchera `Dark `N` Bright` originated
as a controlled cross using Heuchera `B122-9`, a proprietary,
unpatented, unnamed plant as the seed parent, and Heuchera
`B110-5`, a proprietary plant as the pollen parent. These parents
are a result of breeding plan to produce purple leaf Heuchera with
good crowns.
Compared to the seed parent, Heuchera `B122-9`, the new cultivar
has bi-color flowers of pink and white rather than solid hot pink
flowers.
Compared to the pollen parent, Heuchera `B110-5`, the new cultivar
has semi-matte leaves instead of shiny, shorter flower peduncles,
and more crowns.
Compared to Heuchera `Obsidian`, U.S. Plant Pat. No. 14,836, the
new cultivar has flowers that are bi-colored hot pink and white
rather than yellow green.
Compared to Heuchera `TNHEUNEB`, U.S. Plant Pat. No. 30,583, the
new cultivar is smaller in size, has brighter pink flowers and
shorter peduncles, and is more free flowering.
This new Heuchera is uniquely distinguished by: 1. semi-matte,
black to dark purple colored leaves, 2. medium size, rounded lobes
and lightly ruffled leaves, 3. small, bi-colored flowers of hot
pink and white on medium short spikes, 4. good sun tolerance, 5. a
medium, low mounding habit with excellent crown count, and 6.
excellent vigor.
This new cultivar has been reproduced only by asexual propagation
(tip cuttings and tissue culture using growing tips). Each of the
progeny exhibits identical characteristics to the original plant.
Asexual propagation by cuttings and tissue culture using standard
micropropagation techniques with terminal and lateral shoots, as
done in Canby, Oreg., shows that the foregoing characteristics and
distinctions come true to form and are established and transmitted
through succeeding propagations. The present invention has not been
evaluated under all possible environmental conditions. The
phenotype may change with variations in environment without a
change in the genotype of the plant.
