Claims
I claim:
1. A new and distinct cultivar of ornamental Agave plant named
`Stingray` as herein described and illustrated.
Description
Botanical classification: Agave bracteosa (Zucc.).
Variety denomination: `Stingray`.
BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct Variegated
squid Agave plant, Agave `Stingray` selected by Hans A. Hansen at a
perennial nursery in Raleigh, N.C., USA as an uninduced whole-plant
mutation from a tissue cultured crop of Agave bracteosa `Calamar`
(not patented) in the summer of 2009. The new plant has been
successfully asexually propagated by division and shoot tip tissue
culture at a nursery in Zeeland, Mich. Shoot tip tissue culture
propagation systems have been found produce stable and identical
plants that maintain the unique characteristics of the original
plant.
No plants of Agave `Stingray` have been sold, in this country or
anywhere in the world, prior to the filing of this application, nor
has any disclosure of the new plant been made prior to the filing
of this application with the except that which was disclosed within
one year of the filing of this application and was either derived
directly or indirectly from the inventor.
BRIEF SUMMARY OF THE INVENTION
Agave `Stingray` differs from its parent, `Calamar`, as well as all
other Agaves known to the applicant. `Calamar` is a solid green
form of Agave bracteosa. The most similar known Agave cultivars
other than the parent are: `Monterrey Frost` (not patented),
`Summer Snow` (not patented) and `Daddy Longlegs` (not patented).
`Monterrey Frost` has a more white margin, `Summer Snow` has wider
whiter margin, and `Daddy Longlegs` has a subtle chartreuse margin,
rather than the creamy yellow margins of `Stingray`. `Campostella`
(not patented) has variegated leaves with a yellow center and green
margin. `Squiddo` (not patented) has variegated leaves with a
creamy yellow center and green margin. `Moroccan Princess` (not
patented) has variegated leaves with white center and green
margins.
Agave `Stingray` differs from all other Agaves known to the
applicant, by the combination of the following traits: 1. Long,
arching, linear foliage without lateral spines or sharp apical
spines; 2. Leaves have creamy yellow margins and contrasting medium
green leaf centers. 3. Habit is upright near base and arching to
drooping distally.
BRIEF DESCRIPTION OF THE DRAWINGS
The photograph of the new plant demonstrates the overall appearance
of the new plant including the unique traits as a five-year old
plant grown in a container in a greenhouse with supplemental water
and fertilizer as needed. The colors are as accurate as reasonably
possible with color reproductions. Ambient light spectrum,
temperature, source and direction may cause the appearance of minor
variation in color.
FIG. 1 shows a close-up of the new plant in a container with new
foliage in the center.
FIG. 2 shows the habit of the foliage of the whole plant.
DETAILED BOTANICAL DESCRIPTION
The following descriptions and color references are based on the
2015 edition of The Royal Horticultural Society Colour Chart except
where common dictionary terms are used. The new plant, Agave
`Stingray`, has not been observed under all possible environments.
The phenotype may vary slightly with different environmental
conditions, such as temperature, light, fertility, moisture and
maturity levels, but without any change in the genotype. The
following observations and size descriptions are of a five-year old
plant in a commercial wholesale greenhouse in Zeeland, Mich. with
supplemental water and fertilizer as needed. Botanical
classification: Agave bracteosa (S. Watson ex Englm.); Variety
denomination: `Stingray`; Sport parentage: Uninduced whole-plant
sport of Agave `Calamar`; Propagation: Garden division and sterile
plant tissue culture; Time to initiate roots from tissue culture:
About 21 days; Growth rate: Moderate to slow; Crop time: About 16
weeks to finish during the summer in a 3.8 liter container from an
established 2.5 cm tissue culture plug; Rooting habit: Fleshy,
lightly branching, with roots up to 20 cm long; Root color: Nearest
