x Mangave plant named `Sweet Tooth`
Abstract
A new and unique x Mangave plant named `Sweet Tooth`
characterized by a compact, rounded mound of thick, fleshy,
lanceolate, glaucous, sarcous leaves that are mostly flat,
slightly-arching and terminate in a large, firm, apical spine. The
leaves have numerous large, slightly flexible, marginal teeth
curving toward base. Foliage is variegated with dark green margins
and the leaf centers becoming striated with grey and celadon. The
new plant is suitable for the garden or as a potted plant in the
garden or home.

Claims
It is claimed:
1. A new and distinct cultivar of ornamental x Mangave plant named
`Sweet Tooth` as herein described and illustrated.
Description
Botanical classification: x Mangave hybrid.
Variety denomination: `Sweet Tooth`.
BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct x Mangave
hybrid plant, x Mangave `Sweet Tooth` that was discovered by the
inventor at a wholesale perennial nursery in Zeeland, Mich., USA as
whole plant mutation of x Mangave `Tooth Fairy` U.S. Plant Pat. No.
29,599. The new mutation was discovered on Jul. 2, 2018. Through
trials at the same nursery the plant was assigned the code number
18-SP-MANG-699-A. The new plant has been successfully asexually
propagated by division plantlets following coring at the same
nursery in Zeeland, Mich. originally in 2021. The asexual
propagation has been found to produce stable and identical plants
that maintain all the unique characteristics of the original
plant.
BRIEF SUMMARY OF THE INVENTION
x Mangave `Sweet Tooth` differs from its parent as well as all
other Manfreda, Agave and x Mangave known to the applicant. The
sport parent, `Tooth Fairy`, does not have the variegated foliage
with the center streaked with light minty-green streaks and oblong
purplish-red spotting.
The nearest comparison plants are: Agave deserti `Snow Devil` (not
patented); and x Mangave `Carnival` U.S. Plant Pat. No. 31,249,
`Dragon Lady` U.S. Plant Pat. No. 33,985, `Frosted Elegance` U.S.
Plant Pat. No. 32,289, `Pineapple Upsidedown Cake` (not patented),
`Bloodlines` (not patented), `Queen for a Day` U.S. Plant Pat. No.
32,711, `Arctic Fox` (not patented) and `Frosted Jade` U.S. Plant
patent application Ser. No. 17/300,994.
`Snow Devil` has a similar variegation and size, wider, flatter and
thicker leaves with larger teeth that are more green and pointing
more outwardly rather than backward. `Carnival` has a broader
habit, longer, flatter leaves with a solid yellow center, dark
green margins and smaller more flexible marginal teeth. `Dragon
Lady` has a broader habit and the leaves are longer, more folded
and more sinuate with small marginal teeth, dark green margins
yellowish center with both margins and centers heavily spotted with
reddish-purple. `Frosted Elegance` is a much larger and flatter
plant with longer leaves that have a more grayed-green margin and
center is not striated or streaked and does not show purplish-red
spotting. `Pineapple Upsidedown Cake` has a larger and broader
habit, narrower leaves that are solid yellowish with reddish
spotting in the center with a deep green margin and small flexible
marginal teeth. `Bloodlines` has narrower leaves with an intense
purple margin without the striation or streaking in the center.
`Queen for a Day` has broader leaves that are grey-green with
reddish spotting with a purplish margin and smaller, flexible,
marginal teeth. `Arctic Fox` has a larger habit, thinner and more
narrow foliage with smaller, pale-green, marginal teeth, and the
center variegation is a solid whitish-green, the margin is medium
green and the leaves have greyed-purple spotting with high
ultraviolet light exposure. `Frosted Jade` has a solid mint-green
variegated leaf center with smaller more flexible teeth.
`Sweet Tooth` is unique from all the above cultivars and all Agave,
x Mangave and Manfreda known to the inventor by the following
combined traits: 1. Compact, rounded mound of thick, lanceolate,
glaucous, slightly arching, sarcous leaves; 2. Leaf margins develop
large, colorful, apical spines and marginal teeth that are slightly
flexible and change colors and the leaves mature; 3. Marginal teeth
leave an impression on upper and lower leaves above and below from
when tightly compressed in shoot tip; 4. Leaf centers are
variegated with grey and celadon striations; 5. Moderate to slower
growth rate;
BRIEF DESCRIPTION OF THE DRAWING
The photograph of x Mangave `Sweet Tooth` demonstrates the overall
appearance of the new plant including the unique traits as a
three-year-old plant grown in a greenhouse in Zeeland, Mich. 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 side view of the new plant.
FIG. 2 shows a close-up of the variegation coloration and marginal
teeth.
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, x Mangave
`Sweet Tooth`, 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
three-year-old plant in a greenhouse in Zeeland, Mich. with
supplemental water and fertilizer as needed. Parentage: Whole plant
mutation of `Tooth Fairy`; Propagation: By plantlet division
following coring; Time to initiate roots: About 28 days; Growth
rate: Moderate to slow; Crop time: About 24 to 28 weeks to finish
