The Bilyana variety is raised in steel-glass houses. The flowers are white with red strokes (1A1) and are very aromatic. The petals are strongly, shallowly ribbed. The leaves and the stems are grayish green (1D6). The flower holders are strong, erect, and resistant to reclining. The branching form of the flower holder is of the "Elegance" type. The variety is of medium height and blooms relatively early. The plants are capable of forming lateral offspring. The variety is of high yield and quality. The cut flower holder lasts for long, if in water. The Bilyana variety is highly resistant to fusaria. It is grown in steel-glass houses. It is created through hybridisation. It belongs to the "Dianthus caryophyllus" variety.The plants are compact and relatively short (from 70 to 80 cm high). They are apt to form lateral offspring.The average flower size is 5.1 cm in diameter, and 4.5 cm in length. The number of the petals in a flower is 40. They are strongly, shallowly-ribbed.The Bilyana variety blooms relatively early, and the vegetation period is between 208 and 222 days. The cut flower holder lasts for long in water.The variety is of high yield and quality. In the system of the State Standard Catalogue, during both testing periods (1989/1990 and 1990/1991), the Bilyana variety exhibited an output close to that of the standard Red Barbara variety. Upon breeding on a 1 m2, hydroponics extracted 170.9 flower holders. Upon testing its resistance against infection milieu by Race 2 of Fusarium oxysporum f.sp.dianthi, the Bilyana variety exhibited strong resistance.
