This species is supposedly a hybrid of Rosa sericea pteracantha and Rosa xanthina, native to Asia, and is found growing wild in northern Myanmar. It forms large shrubs with stems that have very broad prickles at their base, typical of f. pteracantha, as well as numerous spine-like prickles. Its leaves have small, oval leaflets, numbering 7 to 11.
Flowering: The five-petaled, cup-shaped flowers are pale yellow and highly fragrant. It is the first rose to bloom in Bariloche, from mid- to late November. Its early flowering makes it highly attractive to pollinating insects. It produces small, round, brown rose hips. It is a very fertile species, and because it blooms before any other rose variety in the region, cross-hybridization does not occur. As a result, its seeds produce plants identical to the parent plant.
Varieties at Frey house: In the garden of Frey house, this species has propagated naturally, as its seeds have been dispersed throughout the land, giving rise to new plants without any variants being recorded.

This species is supposedly a hybrid between Rosa sericea pteracantha and Rosa xanthina, native to Asia, and found in the wild in northern Burma. It forms large bushes with very wide thorns at the base of the stems, typical of the f. pteracantha form, along with numerous spiny thorns.
Its leaves consist of small, oval leaflets, 7 to 11 in number. The flowers are cup-shaped, pale yellow with a strong fragrance.
This rose is the first to bloom here in Bariloche, from mid to late November, and is very attractive to pollinating insects, producing small, round brown hips. It is highly fertile, and because it flowers so early, there is no other rose variety in bloom to allow for cross-hybridization, so its seeds produce plants identical to the mother plant.
The Frey estate garden is populated by this species, as its seeds have spread throughout the land, producing new plants, with no variants recorded.
