Claims
What is claimed is:
1. A new and distinct cultivar of Corydalis flexuosa.times.elata
plant named `COURIBLUE` as herein illustrated and described.
Description
Latin name of the genus and species: Corydalis
flexuosa.times.elata.
Variety denomination: `COURIBLUE`.
BACKGROUND OF THE INVENTION
The new Corydalis is the result of a planned breeding program
conducted by the inventor, Jacques Couturieux at a commercial
nursery in Lorraine, France. The seed parent is an unnamed,
unpatented variety of Corydalis flexuosa and the pollen parent is
an unnamed, unpatented variety of Corydalis elata.
The variety was selected after the inventor noted the continuous
flower characteristics. After 2 seasons of observation, the
inventor confirmed a vigorous plant habit and exceptionally long
flowering season of Corydalis `COURIBLUE`.
Asexual reproduction by tissue was first performed in a
non-commercial laboratory during 2009. Plants produced have proved
to be stable and reproduced true to type in successive
generations.
SUMMARY OF THE INVENTION
The cultivar `COURIBLUE` 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 `COURIBLUE`. These
characteristics in combination distinguish `COURIBLUE` as a new and
distinct Corydalis cultivar: 1. Exceptionally long flowering
season, typically in France from the end of April until October,
when the first frosts occur. 2. Continuous flowering. 3. Vigorous,
perennial garden performance. 4. Sweet honey like scent. 5. Unique
blue flower coloration. 6. Good tolerance for cold
temperatures.
PARENTAL COMPARISON
Plants of the new cultivar `COURIBLUE` are similar to the seed
parent, Corydalis flexuosa in most horticultural characteristics.
However, plants of `COURIBLUE` differ in that they are more
vigorous, and more floriferous. Additionally, the flowering season
for `COURIBLUE` is longer, and flowering occurs continuously during
the season, whereas plants of Corydalis flexuosa flower
sporadically.
Plants of the new cultivar `COURIBLUE` are similar to the pollen
parent, known Corydalis flexuosa in some horticultural
characteristics. However, plants of `COURIBLUE` differ in that they
are shorter, and more floriferous. Additionally, the new variety
produces flowers earlier in the Spring, and flowers longer into the
Fall months.
COMMERCIAL COMPARISON
Plants of the new cultivar `COURIBLUE` are similar to the known
commercial variety, Corydalis flexuosa `Blue Panda`, unpatented in
some horticultural characteristics. However, plants of `COURIBLUE`
differ in that they are taller, more vigorous, and more
floriferous. Additionally, the new variety begins producing at
least 2 weeks earlier in the Spring, and flowers longer into the
Fall than `Blue Panda`.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a
typical plants of `COURIBLUE` grown outdoors in a garden in
Lorraine, France. This plant is approximately 15 months old. 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.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The
Royal Horticultural Society Colour Chart 2001, except where general
terms of ordinary dictionary significance are used. The following
observations and measurements describe `COURIBLUE` plants grown
outdoors in Lorraine, France at a commercial nursery. The growing
temperature ranged from 0.degree. C. to 12.degree. C. at night to
8.degree. C. to 22.degree. C. during the day. During the winter
period December to March, plants were sheltered in a large
poly-tunnel with day temperatures ranging from 5.degree. C. to
18.degree. C., and night temperatures ranging from -5.degree. C. to
+8.degree. C. No artificial light, photoperiodic treatments or
chemical treatments were given to the plants. Measurements and
numerical values represent averages of typical flowering types.
Botanical classification: Corydalis flexuosa.times.elata

container.
