Rosa Primula ( Primrose Rose, Rosa ecae ssp. primula (Bouleng.) A.V. Roberts, Rosa primula Boulenger, The Incense Rose)...
...is a species rose originated from Central Asia, found near Samarkand, introduced in Europe a century ago, in 1910.
Its light yellow petals are so delicate and thin, moving like butterfly wings in the breeze.
It has a unique feature in the world of roses: in the rainy days and in certain hours of a day, its leaves emanate an intense perfume of incense which can be sensed from a few meters away.
It produces solitary, cupped, single, fragrant, pale primrose-yellow flowers that are followed by spherical to inversely cone-shaped, brownish maroon hips. Also produces aromatic, dense, fern-like green leaves on slender, reddish-green stems. Most varieties grow on long canes that sometimes climb. Unfortunately, this plant is quite susceptible to a variety of diseases and pests, many of which can be controlled with good cultural practices.
Cultivation: Plant in moist but free-draining or free-draining soil in a sunny, sheltered position. Avoid planting in sites that have previously been used for growing roses.
