Here is the Flora of North America link.http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250092043

Thanks John... I wonder why most times the USDA Plant Profile pages include links to the Flora of North America pages when they exist, but it occasionally they miss adding the links, so I just assumed that part of the Flora wasn't published yet.  Interesting discussion on that FONA page putting into context the relationship between R. integrifolia, its subspecies, and R. rosea.

John, it is an alpine here and tree line is at about 2100-2200m or so.

LoriThat would put it at 8000'< (2500 meters) around here. That narrows the search down a little. ;)Thanks!

Lori, doesn't R. rosea grow in the Rockies too?  I have pictures of what i thought was rosea but perhaps it was integrifolia.  R. rosea is not that common in eastern newfoundland but is downright abundant in western-northern areas where it generally grows kissed by the ocean spray.  I have several in my garden...indespensible alpine in my opinion.

Hi, Todd.  No, it seems R. rosea doesn't occur in the Rockies; here's the distribution of R. rosea , according to USDA Plants:http://plants.usda.gov/java/nameSearch?keywordquery=rhodiola+rosea&mode=...

(The distribution of R. integrifolia is shown earlier also in this thread.)I was mixed up between the two (R. rosea and R. integrifolia) until quite recently... given the number of name changes these two species have undergone, it's no wonder!

Looks like I have to update my Rockies plant pics!

Technically, everything in Colorado should be "integrifolia" but most of the Rhodiolas in the southern part of the state have yellow flowers and look an awful lot like rosea: I think these are basically topotypes and closely allied. I grew a magnificent form of rosea under the rubric of Rhodiola "arctica" that looked more or less the same as what Todd showed: and they all look very much like the roseas from Central Asia I show below. I don't think I have put most of these on NARGS although some of you may have seen them on one of my various cloud repositories for pix that I'm using trying to figure out what to do with the thousands of pictures I take...sound familiar? I start off with two rosea from the Altai mountains of Mongolia (within a few hours march of both China and Russia--in that very corner of Mongolia where their highest mountains are)...the first the common form, the second a sort of monstruouse form. I follow up with a much higher altitude species from cold screes that is not likely to be hardy...the first shot of Rhodiola marginata is of a tiny specimen found growing along a gravelly riverbank far below its preferedc altitude (hence rather stunted) the second a more typical husky clump from high up. Next is is red cousin from the Tian Shan above Almaty: Rhodiola coccinea is stunning and also probably impossible in the garden. And the last few shots are of the gorgeous orange Rhodiola linearifolia I grew for many years in an ordinary scree: this is the gem of Rhodiolas for gardens, I believe...and we have a lot of seed sown this spring...I hope this is one we can introduce soon.

For every minion of the peaks there are a dozen steppe children growing in the dry Continental heart of all hemispheres still unknown to horticulture.

Panayoti, these beauties fire up the imagination, I love the red and orange tones, let's hope that DGB or Plant Select gets Rhodiola linearifolia established in cultivation. In my dreams I grow R. coccinea ;D

Once again a sunny but cold wintery day, I put my google goggles on, strapped myself in my turbo-charged armchair, and took a spin to China looking for more Rhodiola species.  The flora of China lists 55 species, about a dozen and a half subtaxa, with 16 species endemic to China.  I saved you all about 2 hours of clicking on every species, to harvest links to images buried within the species descriptions.  There are also some very nice line drawings.

Mark, thank you very much for doing the time consuming work (albeit a little exciting maybe?) ;)Panayoti, I knew the existence of some of those Rhodiolas but thank you for showing! However, you give me a problem: Now I want to grow them!

Mark, I also appreciate your gleanings.  We all benefit from these extra efforts.

And, I to grow R. coccinea in my dreams!
