Hi Oana -- I'm probably not going to be much help with your specific roses, because I've never grown those varieties. In fact, none of them would be at their best in my Coastal Southern California garden.

So, in order to make sure you get the RIGHT help, you need to tell us where you are located ---- because roses are rather like Real Estate: "Location, Location, Location."

The best treatment for a rose will vary with your specific climate and conditions. So, you most need help from people whose conditions are at least somewhat like your own.

Best of luck! I hope these roses will inspire you to want others!

Oana, WOW! What an amazing collection of roses that you inherited. I don’t grow any of them but also wanted to know where you live. Like Jeri says, location is everything.

I live in Belgium, so the climat is pretty close to what they have at their origins, in UK. The zone is similar to US 8b although I see there are some differences too. It rains a lot, therefore it’s very humid and there is not a lot of light because it’s very cloudy all year around. Temperatures are not extreme, in the summer we normally get below 30 C and in winter above -10 C with no snow blanket. Which means roses don’t really go dormant, more like a short nap in January-February but on the bright side they don’t need to be watered either.

I come from continental weather with knee deep snow and scorching dry summers so my gardening knowledge is below zero. Struggling hard to adapt and missing the sun (imagine a summer with almost no sun), the flowers and real taste of tomatoes. Which is balanced by never having dust on my shoes, chapped lips, split nails or sun wrinkles :D

I wish you had more sun too, Oana. Organic fertilizer twice per year could be helpful and glad you have water. Lack of sun can be the factor with less blooms.

Thanks. Would pegging help? I don't think it can hurt. Also for the blackspots I hear planting tomatoes in the rose bed can help. I have some bush types I could plant next year instead of delphiniums.

Pegging could help. It is a lot of work to do. I won't spray anything and put up with BS on occasion.

I wonder if the Hybrid Musk class of roses would do really well for you? They are mostly shade tolerant as a class so they might bloom more in your cloudy summers. Plus with your rain you probably have lower pH soil and they really like that.

Welcome to the Gardenweb!!! I hope you'll continue to post once things get figured out. I spent many formative years in Belgium so I'm very familiar with the climate even in these days of global warming. However, Belgium is a fantastic place for growing roses and they're widely grown. I would think the Austins would do fantastic, but even England gets more sun. Perhaps a picture of the unknown rose? You could try a baking soda type Cornell mix for the BS when it appears and a dilute skim milk can help with powdery mildew, but for a once bloomer I'm thinking why bother. You have a long growing season so you might as well have some repeat bloomers.

Stephainie mentions a WONDERFUL solution with the Hybrid Musks. Belgium has one of the foremost breeders of modern HMs with Louis Lens so if you have time a visit to his nursery at Oudenburg near Brugges would make a wonderful and informative day trip. Maybe you could call for suggestions or visit of the large rose gardens to see what does well. Of course there are always the Pemberton and Bentall Hybrid Musks. Take a look at Felicia, Ghislaine de Feligonde, Belinda and Bubble Bath. Pink Pet is also great in a humid climate and I know the Aspirin Rose is very healthy there; it's one I'd love to grow stateside. : ((

Hex castle is particularly beautiful. Your adopted country helped inspire my love of roses; I hope this helps do the same for you! : ))

I garden in completely different conditions down here in Italy, but second the idea of Hybrid Musks, and suggest you look into Hybrid Multifloras in general: they seem to popular in your part of Europe, and, terrible maladapted to my dense clay and summer drought, they apparently do well in your conditions. I don't know how disease-proof they'd be in your conditions. It sounds as though you may have to remove some plants to give the remaining ones room to grow. Also, would you be open to the possibility of once-flowering roses, and other plants for seasonal change in bloom? I have a lot of once-blooming roses and adore them, but it's also true that I have a lot of room for growing a variety of things. Good luck!

P.S. 'Constance Spry' is magnificent and, if it does well in your conditions, I'd recommend keeping it. I gave it once years ago as a housewarming gift to a friend, who asked me in puzzlement a few years further on why it didn't flower. Turned out she was pruning it hard and way too late, so cutting out the coming flowering growth.

P.S. Do you have any pictures of your mystery rose? It sounds really interesting!

I just researced European sunshine per year, and it seems that Belgium, the UK and Denmark (where I live) get about the same amount of sunshine. Which means that the small flowers are probably due to too little fertilizer. You could also try to move one or two of the roses to allow them more space.

I second the suggestion of Aspirin and Ghislaine de Feligonde, both very good doers here.

Lastly, a photo of my aunt's stunning Honorine de Brabrant in Copenhagen.

Thank you all for the replies. I'm very excited about visiting the rose creator Vaporvac is mentioning. Next summer when the roses are in bloom so I can see how they look and smell them myself. I would need to decide either to replace some or change the garden layout.

My neighbour has a Hybrid Musc, very tall and healthy and it smells heavenly on my terrace. They also grow throughout the city in parcs ans alleys.

For the HdB, pegging or growing around a cone, why not both since I have two small bushes. I could test and see what works best.

For the blackspot I thought of planting tomatoes throughout the rose beds; I hear they are perfect companions.

About the mystery rose, this is where it grows, on the right wall competing with a wisteria and a trumpet Vine. Doesn't stand a chance, it's a wonder it made 5 blooms all year. I don't have a pic of itself since I never thought I needed one but in the wisteria pic you can see the poor thing launching itself right in the middle of the wall. It grows to surpass it by a couple of meters in height if I let it, but this year I pruned it. I do have however a picture of the bloom in all its Glory. About 5-7cm across.

As a treat, here is the Bobby James immortalized before I cut the main trunks and two tons of foliage. Impossible to give it the TLC it needs with our busy schedule so we thought that by downsizing it and regenerating the canes we might be able to keep it. Unfortunately it's full of mildew that it spreads on the rest of my garden. Snif.

Oh, I wish you would have left this beauty, Oana. That is my favorite look. Beautiful.

There are various hardy foetida/pimpinelliafolia hybrids and at a wild guess your mystery rose belongs to this group. Varieties that come to mind are some of the 'Fruehlings-' roses and 'Goldbush', though I know these as shrub roses, not as climbers. Suggestions, fellow forum members? Oana, do you recall what kind of scent your mystery rose has?

Could the yellow rose be Aglaia:

Or even the double yellow Banksia?

The leaf shape and flower colour does not look like Fruhlingsduft, which is also more of a shrub than a climber. But marvellous!

Not a banksia for sure.

I remember the smell was very light citrus tea. The new basal shoots also got to 5m tall in one season. My attempts to tie it horizontally didn't produce much result, only spindly side shoots but I'll blame it on the trumpet Vine smothering it and lack of fertilizer for many years when the house was rarely inhabited (2nd residence). I will cut down all the old barky canes and see what it does next year. No problem, it doesn't need a name to be loved.

True, it doesn't need a name, but I'm curious! Okay, a multiflora climber or a wichuriana? Ideas, folks?

Found one that looks similar, just shorter: Golden Gate

If it is the Kordes climber you found, I would say you have a match :)

Another one for my too long wishlist, oh no...
