I'm no expert on hybrid musks--I have a young Felicia which I adore and will be planting a new Cornelia tomorrow--and grow a couple other HMs (but not Pax, unfortunately).

One I really like is called either a hybrid musk or hybrid muliflora or even a rambler (I don't know why someone can't make up their minds on this)--anyway, Ghislaine de Feligonde. Do you know her? She's described as light yellow on HMF, but she is usually? often? white, yellow, apricot--absolutely lovely mixture. She can take some shade and is a good grower.

Of course mine is only a couple years old, so I can't say how well she will do in the long run, but so far, I'm absolutely delighted with Ghislaine.

'Cornelia' is more distinctive, has sometimes been very highly rated in ARS polls.

'Ghislaine' opens strong orange, then quickly goes nearly white. The plant is glossy-leaved and care free but rather heavily armed and wild in aspect.

Here, Cornelia hardly blooms. They are small and lightly scented. Felicia, which I lost, bloomed much more often, were larger with larger clusters and was my favorite scent in the garden. She will be replaced when the opportunity strikes.

I have both. In my conditions, hybrid musks generally have two big flushes, one in the spring and the other in the fall, with just scattered bloom in between. After 2 years in the ground, Felicia is still getting established, so I can't really comment on the bloom (has been sparse) or scent (different from Cornelia's, and not strong as yet), but the flowers are larger. Cornelia is established (7' x 7' on a fence) and I love the charming multi-colored effect of the blooms (ranges from near apricot to strawberry and then to light pink as they age) -- and yes, the scent, which I love, does waft a long way. Cornelia's foliage is nicer than Felicia's here -- Felicia more subject to PM, but that may change once she becomes more mature.

Both have been irrigated once a week during the dry season with a soaker hose giving water depth to about 9 - 12" -- as drought tolerant as any of the teas, I would say, and not as water-needy as an Austin.

I have grown Felicia for nearly 30 years and have kept her at 6'x 6' as a shrub in z10 Melb. Aust., otherwise I end up with octopus canes with flowers on top. My soil is clay and the rose is grafted on either Multiflora or Dr. Huey. She has survived a couple of droughts with only rainfall or the odd bucket of grey water and although the bloom cycle was curtailed she did flower during the cooler months. The scent is noticeable as one walks by. My other HM is Penelope which is 7'x7' on a fence, now almost completely shaded by eucalyptus trees on neighbouring properties. She also grows and flowers well in spite of invading roots from the trees; also a drought survivor but did go into hibernation for about 6 months towards the end.

I love the Pemberton Hybrid Musks but don't grow them well; the main problem, I think, is that I've neglected to give them the maintenance pruning they require. You have to cut out old canes regularly. They're roses for people who love good foliage, graceful habit, and scent, and don't demand large blooms or strong colors.

'Cornelia' when well grown is in my opinion one of the most beautiful roses in existence, with lovely foliage, habit, and a sweet scent that carries. It has a lax habit and can be grown as a floppy shrub, with support, or as a small climber. Similar in habit are 'Buff Beauty', 'Pax', 'Moonlight', and 'Kathleen'. 'Felicia' is shrubbier and less distinctive in character. I've never grown it well, so can't judge its beauty, but I grow it very willingly because it has one of the finest scents of all roses: old rose mixed with musk sweetness, carrying on the air.

In our climate, with our heavy soil and good annual rainfall, the Hybrid Musks can go without summer watering, though of course they won't flower in dry conditions. As best as I can judge, given my relative lack of success growing them, in a hot dry climate they like cooler and moister conditions and part shade. Our neighbors grow 'Cornelia' very well espaliered against a wall that looks northwest.

All this has reminded me that some time in my life I need to find a place that Hybrid Musks might like, prepare it really well, and then grow them there. Make them a little garden. Heaven knows the last thing I need is another project, but I would like to see them in their glory. My favorites are 'Cornelia', 'Pax', 'Francesca', 'Vanity', 'Kathleen', and 'Felicia' for fragrance. 'Penelope' is also very good: for some reason I tend to forget it. Also 'Buff Beauty', which many people love. 'Pax' is a very elegant rose for its long buds and the contrast between their whiteness and the dark leaves. The fully open flowers are less exciting, but they're fragrant and the plant has the usual graceful habit and good foliage.

Nik, I can't comment on Cornelia. I've been growing Felicia with only 3 hours of sun of afternoon sun in climate very different than yours, i.e. adequate rainfall, hot & humid heat waves and very cold winters. The spring flush is quite spectacular, thought the fall repeat has been inconsistent. Last year I had no fall flush yet the year before I had a small repeat.
What I love about her, is her delightful old rose scent and her propensity to waft. The scent in close quarters has a faint twist of myrrh.

I grow Ballerina, a Bentall hybrid musk. No scent but more often in flower.
Albas and some species are other shade tolerant roses, though I'm not sure if you can grow Albas in Greece....

Yes, I can grow Albas where I live (at least some of them). They perform 'adequately' given my climate and their performance varies year on year, as expected. Very short flowering period before they get stunned by the heat though, similarly to other once blooming european OGRs. At least I get to see and smell roses every year.

There's not one climate in Greece btw, it varies from alpine to temperate, from subtropical to desert like, a somewhat curious fact given the small size of the country explained by the very varied topography, the proximity to the sea and the fact that we are influence by weather patterns stemming from NE Europe and N Africa alike. Areas in more northern latitudes, further from the sea or in higher altitudes are very suitable for these kinds of roses and in southern areas with warmer winters than my place or in low lying islands will have difficulty in growing them. My case is boundary, I suppose. I can grow almost all kinds of roses, I believe (given enough supplementary watering). Water is the main problem where I live. That and PM and calcareous soil.

Thanks Nik for the clarification & geography lesson :-)
I should've said your region, my bad.
Then the Albas might like the shadiest part of your property.
I don't know how drought tolerant they are.
I always consider their hips as 2nd flush.

Yes, indeed I have most of my old european single blooming OGR's in partial shade and the few albas in what could be called very partial sun. I too cannot comment on their drought tolerance as my soil is too varied in terms of water retention capacity and the garden too varied in terms of competition by trees and native plants to draw any sensible conclusions. What I can say though is that albas, contrary to popular beliefs, do not seem to be too dependent on chill hours (in the strictly defined terms as is the case with many stone fruit trees for example) but on the existence of a well defined cool period during which they can rest (helped by laborious de-leafing by yours truly..).

I've grown both, but my climate is very different from yours. I much preferred Cornelia to Felicia. Cornelia grown as a short climber is spectacular with wafting fragrance and a really good fall rebloom (though not much in summer). Felicia had blackspot and vigor issues and I no longer grow her.
