There were 2 fine specimens of this at the Snug Harbor Botanical Garden in NYC, but with the change in management they finally dwindled away to nothing since the first time I saw them about 10 years ago. Shame: bit odd-looking, wirey plants and rather tired-looking foliage, but the color was impressive, and there was the interesting fruity smell to the new leaves.

Was mistakenly sent this instead of the plain yellow foetida...not a big issue, was primarily interested in the alledged fruity glandular smell of the buds.
The glandular buds do quite strongly smelly of a sweety fruity scent. The unpleasant scent of the follow I haven't detected much of (yet...the one bloom so far isn't in direct sunlight for another hour or so). The very dark (near black) pistils are also interesting.
So far no issues with health (early spring....very wet though)

Bog off! As the supermarkets say, Buy One Get One free. At sometime your 'Bicolor' will probably start reverting back to plain foetida.
Its fragrance is similar to Rosa fedtschenkoana, not attractive but not totally horrid either.
I tried a plant for the first time last year expecting dreadful blackspot in a climate with cool wet summers. The rose is grown well away from other roses (its only rose companion is 'Agnes' that is growing very well and healthily) near the top of a south-west facing slope where it can take advantage of as much warm sun as possible and excellent drainage. Up until mid-July we had an exceptional hot dry summer but since then there has been a fair share of dampness and heavy dews that we get regardless of how hot it is. The rose grew about five shoots 40CM long and there has been little sign if any of blackspot. We had gales yesterday and again today so most of the leaves have blown off now.

I assume that is probably true. It's not a big issue...as far as wrong plants go it's pretty minor.
Will be interesting to see how blackspot goes (or doesn't) with it here in Sydney Au, spring and autumn (summer is too hot, seems to kill it) is often a high blackspot area.
Either way the glandular buds are very interesting and will be something I will be attempting to bring and enhance to a repeating plant....just may take a few steps and growing out an absurd number of F2.

I was told that by the time, later in the summer, that blackspot tends to take hold it has already made its years growth and will flower well again the following year regardless of how awfulf it might look. I suspect it's proneness to disease might have something to do with trace elements in the soil, particularly boron, as much as the climate has.

Only two weeks later, but still no BS and there is quite a lot of it in my garden and nearby foetida, it's interesting considering how much blame is placed on this species contribution to BS in moderns.
Also I see what you said earlier about sporting, one cluster had blooms that were half reverted.

I'm sure it blackspot is made far worse by the absence of certain trace elements and perhaps lime in the soil.

Newly planted this year Rosa foetida 'Bicolor' is has produced five shoots 30cm long and shows no signs whatsoever of blackspot.
The smell reminds me of the odour that the sheildbug, Palomena prasina, makes when it is distressed or maybe Perigord truffles or the inside of a well worn Wellington boot.

Just think, you could make a fortune selling welly omelettes.

I've just had this rose arrive in the post as I like roses that are historically important rather than beautiful but was always put off by not thinking I could grow it. I'm not sure how a rose from dry arid regions will grow in my climate. The eastern side of my garden slopes steeply toward the south-west and catches all the late evening sun, it is the warmest and driest conditions I have with good air movement too. 'Anges' grows very healthily here reaching 160cm X 140cm in three seasons so I'm going to give it a try.
