|'Quatre Saisons Blanche Mousseuse' is an open, arching moss rose producing loosely formed, cupped to flat, double, scented white flowers with light green leaves. Stems and buds are covered with stiff, brownish green moss. This rose is of the damascena var. semperflorens species. Also sold in plant nurseries as 'Perpetual White Moss' or 'Rosier de Thionville' rose.
In general, roses are a large group of flowering shrubs, most with showy flowers that are single-petalled to fully double petalled. Leaves are typically medium to dark green, glossy and ovate, with finely toothed edges. Vary in size from 1/2 inch to 6 inches, five petals to more than 30, and in nearly every color. Often the flowers are very fragrant.
Most varieties grow on long canes that sometimes climb. Unfortunately, this favorite plant is quite susceptible to a variety of diseases and pests, many of which can be controlled with good cultural practices.
