Botanical classification: Liriope muscari.
Varietal denomination: Sno Cone.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Liriope muscari and will be referred to hereafter by its cultivar name, Sno Cone. Sno Cone is a new cultivar of lilyturf or border grass and is a grass-like perennial herb in the Lily family grown for landscape and container use.
The Inventor discovered Sno Cone as a naturally occurring whole plant mutation of Liriope muscari in summer of 1988 in his garden in Greenwood, S.C. The parentage of Sno Cone is unknown.
Asexual reproduction of the new cultivar was first accomplished by division under the direction of the Inventor in Dahlonega, Ga. in summer of 2004. The characteristics of this cultivar have been determined both by division and in vitro propagation to be stable and to reproduce true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. The new Liriope has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in temperature, day-length, light intensity, soil types, and water and fertility levels without, however, any variance in genotype. The general observations, and descriptions that follow describe plants that have been observed over a period of ten years in Greenwood, S.C. These attributes in combination distinguish Sno Cone from all other selections of Liriope known to the Inventor.
- 1. Sno Cone exhibits a tight clump forming, non-spreading growth habit.
- 2. Sno Cone exhibits foliage that emerges greenish-white in color and becomes whiter in color with maturity, the white coloration is maintained throughout the growing season.
- 3. Sno Cone exhibits foliage that is strongly recurved.
- 4. Sno Cone exhibits ornamental berries in fall that are uniquely colored with a mottled pattern of dark purple, green, and white.
- 5. Sno Cone reaches a height of 30 to 40 cm (12 to 16 inches).
Sno Cone can be compared to the cultivar Okino (not patented), which is similar in having white and green foliage, Sno Cone differs from Okino in being taller, in having a more vigorous growth habit, and in having foliage that is more recurved, broader in width, and that maintains its white coloration throughout the growth season. Sno Cone can also be compared to the cultivar Big Blue (not patented), which is similar in having a tight clumping habit. Sno Cone differs from Big Blue in having foliage that is more recurved and in having white and green foliage whereas Big Blue exhibits blue-green foliage.
DETAILED BOTANICAL DESCRIPTION
The general observations describe plants of Sno Cone that were observed for 20years in a garden in Greenwood, S.C., while the detailed botanical data describe one year-old plants as grown in one-gallon containers in Alpharetta, Ga. The color determinations are in accordance with the 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
