I am gardening in south central Texas, USA.

I've been growing this species for three years now. The 6ft height is pretty much right on. The thin canes grow up to about 6 ft and pretty much stop. The ferny foliage alone makes it worth growing for garden value. The fall (winter for us) display is very colorful - even this far south.

The flowers are wornderful, but a bit sparse for me. It would probably be better in a location that got a more of a winter chill. The flowers are borne close to the cane in small clusters - and sometimes singly. The fragrance is sweet and moderate to strong. There is very little lateral growth other than the flowering shoots. The plant pefers to throw new growth up from the bottom forming a nice thicket. Don't plant it unless you can live with a plant that runs at the root.

It sets seed with ease and you get pretty good germination if you do two stratification periods. The seedlings have been barely to moderately suseptible to mildew. They have not grown enough to provide any other insight.

The rose itslef has had no diseases, but the spider mites do seem to love it. My only complaint about this plant is that it is not at all tolerant of alkaline soil/water. As this is a common problem where I live, fighting chlorotic foliage has been a never ending battle. For me, its well worth the effort. If you live in an area of high alkalinity and you don't want to bother with the exra effort, then I would suggest you plant a different species rose.

Thanks for the information about alkalinity. Our soil and water are also very alkaline here in Albuquerque.

Is this the same as Rosa dahurica ?


Cahiers
Ferdinand de Sausser (1964) p. 144
The specific name dahuricus (passim, especially in the works of P. S. Pallas, davuricus, also dauricus) was applied by early explorers to certain Siberian flora and fauna, e.g., ... rosa dahurica, seu davurica (P. S. Pallas, Flora rossica ... cit. supr. i. II 61)

Rosa marretii, and Rosa amblyotis are the two synonyms of this rose. The species is a member of the Cinnamomeae and closely allied to Rosa Cinnamomeae its self. This species is one of the parents of parents of Thérèse Bugnet.

Upright shrub to 6ft (2m), light green, sometimes downy leaves , flowering in June and July, globular to pear-shaped red hips.

Very disease resistant.

The species is fully hardy in Zone 3and probably hardy to Zone 2a or lower
