English Abstract

Germi tion, growth and brush cutting resistance of Sisyrinchium rosulatum BICKN., one of the perennial herbs with light purple-or white-colored flowers, were studied for verifying the creating technique of low stem wild flowering greens.
Results were as foliows.
1) Germi tion habit
Seed of S. rosulatum was light germi tor, and did not demand low temperature treatment. The optimum germi ting temperature of this plant was from 15 to 20°C.
2) Growth habit
S. rosulatum was evergreen, almost. Its flowering term was from May to November. It was suggested that this plant mainly developed upperground organs using underground or upperground nutrient from April to September. The translocating term of upperground nutrients to underground organs was from September to November.
3) Resistance to brush cutting
S. rosulatum died consequently from brush cutting every two weeks. But, this plant grew vigorously, flowered and seeded below the cutting frequency of every four weeks.
