ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of
Yucca recurvifolia
Salisb. Which was discovered as a whole plant mutation in a controlled planting of
Yucca recurvifolia
in Fulshear, Tex. The varietal denomination of the new variety is ‘Hinvargas’.
The genus Yucca is included in the family Agavaceae which comprises about 40 genera of evergreen trees and perennial and herbaceous plants mostly originating in tropical and subtropical regions of the Northern and Southern hemispheres. The genus Yucca comprises at least 34 species of evergreen trees and perennial and herbaceous plants, many of which possess desirable ornamental characteristics.
Yucca recurvifolia
is native to the Eastern United States. It generally has lanceolate leaves to about 90 cm. long and to about 6 cm. wide.
Yucca recurvifolia
is fully evergreen depending on winter temperatures. Leaf color ranges from light to dark green, depending on light intensity and cultural conditions. Flowers of
Yucca recurvifolia
are borne on an erect, narrowly conical panicle to about 1 m. tall and about 30 cm. wide. Flowers are borne from between July to September in Texas.
Yucca recurvifolia
is believed to have been in cultivation in Europe and North America for about 200 years. Only four cultivars with colored foliage are known to have been grown: (1)
Yucca recurvifolia forma marginata
(Carr.) Trel., which has leaves with pencil-width marginal variegation; (2)
Yucca recurvifolia forma variegata
(Carr.) Trel., with central yellow variegation; (3)
Yucca recurvifolia forma elegans
Trel., which has reddish central variegation; and (4)
Yucca recurvifolia forma rufocincta
Baker, Gard., a lower-growing form with reddish-brown margins.
SUMMARY OF THE INVENTION
The new variety was discovered as a whole plant mutation in a controlled planting of
Yucca recurvifolia
in Fulshear, Tex., and differs from other known varieties of
Yucca recurvifolia
in its yellow to yellow-green variegated foliage, exhibited as between 1 to 3 mm. Wide vertical bands running the length of the leaves. Asexual reproduction of the new variety by root division performed in Irvine, Calif., Vacaville, Calif; and Fulshear, Tex., have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations, and the new variety reproduces true to type.
COMPARISON WITH PARENT
‘Hinvargas’ is distinguished from its parent and all other varieties of
Yucca recurvifolia
of which I am aware by its yellow to yellow-green variegated foliage, exhibited as between 1 to 3 mm. wide vertical bands running the length of the leaves.
