We claim:
1. A new and distinct cultivar of Dogwood tree, Cornus florida,
named `ERICA'S APPALACHIAN SUNRISE`, as illustrated and described.
Description
The Sequence Listing for this application is labeled "Seq-List.txt"
which was created on Oct. 29, 2019 and is 4 KB. The entire content
of the sequence listing is incorporated herein by reference in its
entirety.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
flowering dogwood tree with a mixture of both fully dark red and
lighter red bracts. This new cultivar was the result of a
controlled cross that produced a few seeds, which were planted in a
greenhouse in Knoxville, Tenn. This new cultivar was discovered
among the resulting seedlings. This dogwood tree is botanically
known as Cornus florida L. and is hereinafter referred to by the
following cultivar name: `Erica's Appalachian Sunrise`. Analysis
has shown that this new dogwood cultivar is the result of
self-pollination of the dogwood cultivar `Cherokee Brave` (U.S.
Plant Pat. No. 10,166). The seedling of `Erica's Appalachian
Sunrise` was harvested on its own rootstock. Results have shown
that the unique features of this new dogwood cultivar are stable
and reproduced true-to-type in successive vegetative
generations.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1. Photograph of one type of bracts and flowers of the dogwood
cultivar `Erica's Appalachian Sunrise`. This bract has fully dark
red coloration and is less than about 5% of the bracts produced by
the cultivar. Colors in the photograph may differ from actual
colors due to lighting and light reflectance.
FIG. 2. Photograph of `Erica's Appalachian Sunrise` dogwood
cultivar showing the other type of bract and flowers produced more
than about 95% of the time on the dogwood tree, which has lighter
red or more pink bracts. Colors in the photograph may differ from
actual colors due to lighting and light reflectance.
FIG. 3. Photograph of new leaf growth on `Erica's Appalachian
Sunrise`. Colors in the photograph may differ from actual colors
due to lighting and light reflectance.
FIG. 4. Photographs of the bracts and flowers of dogwood cultivars
`Cherokee Brave` and `Karen's Appalachian Blush`, (U.S. Plant Pat.
No. 13,165), which were initially crossed. Results show that the
resulting F1 cultivar, `Erica's Appalachian Sunrise`, is not, as
was expected, related to `Karen's Appalachian Blush`, but is the
result of self-pollination of `Cherokee Brave` (U.S. Plant Pat. No.
10,166). It can be seen that the lighter red or pink bracts of
`Erica's Appalachian Sunrise` (shown in FIG. 2) closely resemble
the bracts of the parent, `Cherokee Brave`.
FIG. 5. Photograph of the less commonly produced bracts and
flowers, less than about 5%, of the dogwood cultivar `Erica's
Appalachian Sunrise` (top--fully dark, red bracts), and those of
`Karen's Appalachian Blush` (bottom left) and `Cherokee Brave`
(bottom right).
DETAILED DESCRIPTION OF THE NEW VARIETY
A new and distinct cultivar of flowering dogwood tree producing
both fully dark red bracts and lighter red or pink bracts. Both
types of bracts are significantly smaller than the bracts of the
parent cultivar, `Cherokee Brave`. This dogwood tree cultivar is
botanically known as Cornus florida and referred to by the
following cultivar name: `Erica's Appalachian Sunrise`. This
cultivar appears to be highly resistant to powdery mildew caused by
Erisphe pulchra.
This new and distinct dogwood tree cultivar is a product of
self-pollination of the dogwood cultivar `Cherokee Brave`. The
subject dogwood tree cultivar differs from `Cherokee Brave` in that
the instant cultivar produces significantly smaller and both fully
dark red bracts and lighter red bracts and also exhibits greater
resistance to powdery mildew.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and comparisons describe
this cultivar grown in Maryville, Tenn. Trees used for this
description were about ten (10) years old. Both the fully dark red
bracts and lighter red to pink bracts are substantially the same
size, though significantly smaller than the bracts produced by the
parent cultivar. Plant hardiness is expected to be zones 4-9. The
color characteristic descriptions use color references to The Royal
Horticultural Society (R.H.S.) Colour Chart, The Royal
Horticultural Society, London, UK, 4.sup.th Edition, 2001, except
where general terms of ordinary dictionary significance are
used.
A bee-mediated pollination between the dogwood cultivars `Cherokee
Brave` and `Karen's Appalachian Blush` was conducted in April of
2009. Seeds were collected from both cultivars and planted in a
greenhouse in Knoxville, Tenn. This new and distinct dogwood tree
cultivar was discovered among the planting and germination of the
seeds harvested from `Cherokee Brave`. The following Table 1 shows
the alleles at nine (9) loci compared between the cultivars
`Karen's Appalachian Blush` (U.S. Plant Pat. No. 13,165), `Cherokee
Brave`, and the new cultivar `Erica's Appalachian Sunrise`. As seen
in Table 1, the alleles for `Erica's Appalachian Sunrise` are
identical at all nine (9) loci to those of `Cherokee Brave` and
have no alleles that match `Karen's Appalachian Blush`. This
demonstrates conclusively that dogwood cultivar `Erica's
Appalachian Sunrise` was the result of self-pollination of
`Cherokee Brave`. Asexual reproduction of `Erica's Appalachian
Sunrise` by grafting of axillary buds onto seedling rootstocks has
shown that the unique features of this new dogwood cultivar are
stable and reproduced true-to-type in successive vegetatively
propagated generations.

Botanical classification: Cornus florida `Erica's Appalachian
Sunrise`. Unique features: A mixture of two types of bracts, a
first one being less than about 5% of the bracts produced that is
fully dark red and a second type being more than about 95% of the
bracts produced that is similar in color to the bracts produced by
the parent `Cherokee Brave`. Both types of bracts on `Erica's
Appalachian Sunset` are similar in size and significantly smaller
than the bracts produced by the parent `Cherokee Brave`. Fewer
flowers per inflorescence of `Erica's Appalachian Sunset` than on
`Cherokee Brave`. Disease susceptibility: `Erica's Appalachian
Sunrise` has a strong resistance to Powdery mildew caused by
Erisphe pulchra and only some spotting caused by Elsinoe corni, a
cosmetic disease with little damage. Insect damage: None noted.
