|Primula is an erect to arching species rose producing solitary, cupped, single, fragrant, pale primrose-yellow flowers that are followed by sherical to inversely cone-shaped, brownish maroon hips. Also produced are aromatic, dense, fern-like green leaves on slender, reddish-green stems. Also known as Incense 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. Unfortunatly, this favorite plant is quite susceptible to a variety of diseases and pests, many of which can be controlled with good cultural practices.
