ABSTRACT:
Botanical classification/cultivar designation:
Yucca recurvifolia
cultivar Monca.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Yucca plant, botanically known as
Yucca recurvifolia
, and hereinafter referred to by the cultivar name Monca.
The new cultivar was discovered by the Inventor in a controlled environment in Azusa, Calif. as a naturally-occurring whole plant mutation of an unidentified selection of
Yucca recurvifolia
, not patented. The new Yucca was observed as a single plant in a group of plants of the unidentified selection of
Yucca recurvifolia
on Oct. 13, 1999. The selection of this plant was selected on its unique leaf variegation pattern.
Asexual propagation of the new cultivar by tissue culture propagation at Azusa, Calif. since Oct. 13, 1999, has shown that the unique features of this new Yucca plant are stable and reproduced true to type in successive generations of asexual propagation.
The new Yucca has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Monca’. These characteristics in combination distinguish ‘Monca’ as a new and distinct cultivar:
1. Compact, upright and outwardly arching growth habit.
2. Long narrow sword-like leaves.
3. Dark and light green variegated leaves.
Plants of the new Yucca differ from plants of the parent selection in the following characteristics:
1. Plants of the new Yucca are more compact than plants of the parent selection.
2. Leaves of plants of the new Yucca are shorter, narrower and more recurved than leaves of plants of the parent selection.
3. Leaves of plants of the new Yucca are variegated whereas leaves of plants of the parent selection are not variegated.
The new Yucca can be compared to plants of the
Yucca filamentosa
cultivar Golden Sword, not patented. However in side-by-side comparisons conducted in Azusa, Calif., plants of the new Yucca differed from plants of the cultivar Golden Sword in the following characteristics:
1. Leaves of plants of the new Yucca were broader than leaves of plants of the cultivar Golden Sword.
2. Variegation pattern of leaves of plants of the new Yucca was less distinct than variegation pattern of leaves of plants of the cultivar Golden Sword.
3. Plants of the new Yucca were not as cold temperature tolerant as plants of the cultivar Golden Sword.
