Austins in Pennsylvania Ohio River valley
Comments (8)I have lived in California for many years, but I began my rose growing career in Butler County, Pennsylvania, so I am familiar with what you face. Hybrid perpetuals and bourbons are not your best bets. Even here in dry California they benefit from spray. If you love these roses so much you are willing to experiment, I would suggest 'Joasine Hanet', 'Sidonie', and 'Yolande d'Aragon' as the best to grow in a no-spray regimen. They may still get blackspot, but they are the most disease resistant HPs I know of. Here the found rose Grandmother's Hat is also highly disease resistant, but I have heard that it does not do quite as well in humid climates. Still, if you want to try it, it might be worth the risk. All four of these are fragrant and lovely. Do not ignore the rugosa class. Most of them repeat well, are highly disease resistant, cold tolerant, and very fragrant. I love them, but alas, they simply do not grow well in my climate and soil. I do grow one (Dart's Dash) even though it is not happy with the western alkaline soil. They will sucker and spread if grown on their own roots, so you might consider getting them grafted. Pickering Nursery is an excellent source for grafted rugosas. I should mention that the rugosa roses cannot be sprayed. As Mad Gallica mentioned the once blooming European old garden roses are less susceptible to black spot than later classes of roses. Albas and damasks are the most fragrant. Gallicas are moderately fragrant. Gallicas and some of the others will sucker and spread the same way the rugosas do, growing like a thicket. If this is fine with you, go for it. If not you will want to grow them grafted. Again Pickering is a good source. When considering once bloomers, consider ramblers. Some are very fragrant, some are not. Keep away from Dorothy Perkins. I don't think it gets much blackspot, but it gets horrible powdery mildew. But there are literally hundreds of ramblers, some of modest size, some big enough to climb into trees or swallow a shed. Many are not much planted because people are unwilling to plant once bloomers, but they are stunning when in bloom. I myself would not want a garden comprised entirely of once blooming roses, but I think a very good argument can be made for planting 10% of your roses as once bloomers. When in bloom, they outshine anything else you can imagine. There are modern shrubs that are bred for disease resistance. Kordes in Germany is famous for this and has produced some lovely roses, not only disease resistant but also cold hardy. Until recently they did not seem to be selecting for scent, though I do believe some of their recent introductions are fragrant. The ones I have grown were not, but I have not grown many of them. Among the Austins, look among more recent introductions. Disease resistance did not seem to be high on his list of characteristics in the early days, though I'm sure a few were. Mayflower is the first one to be marketed for that quality. There are other breeders who are selecting for this particular trait, and also for fragrance. Paul Barden who sometimes posts here is one. His roses can be found at Rogue Valley Roses. Tom Carruth also considers these two qualities (also stripes, also near-blue color). He currently works for Weeks Roses. He also has posted here from time to time, though I haven't seen him in several years, perhaps because I spend less time on the Roses Forum than this one. And also, please remember that disease resistant does not mean disease immune. All roses get some disease at some point. However, the level of disease varies widely. So that you will get a clear idea of how I judge disease resistance, I'll describe my own practice. I do a single dormant spray of copper (organic) once a year after pruning to break the disease cycle, and no other spray for the rest of the year. Roses that cannot perform reasonably well with this practice will be removed. As I mentioned, my garden is in a low rainfall, semi-arid area. (More arid than semi this year!) Black spot exists here, but rust and powdery mildew are the diseases we worry about more.

Comments (10)I did 260+ containers winter sowing. If anyone is interested, I can email the database. It's a little nuts. Comparing my list to yours, my Linaria germinated well and planted out fine. I'm wondering if I have it in too much sun. We'll see. Chinese houses germinated fine, but I forget where I planted them, so I can't report on blooms. Oh well. Larkspur Imperial Giants have great germination, beautiful plant out and are ready to pop! My tithonia containers did not germinate. They were all trades I think. Poppies of various varieties germinated well, but I lost a few to frying. Otherwise, I have blooms getting ready to burst in a variety of pockets. Black Hollyhocks were half and half, but some are planted out and doing fine. Can't tell you my secret - just plunk them in milk jugs with miracle gro potting soil and throw them out in the snow. I like your list - am taking a few notes if you don't mind....See MoreWinter Sowing in the Ohio Valley
Comments (13)Am I to late? I wanted to try Wsowing this year. I was a newbie to gardening this summer. Can't wait till spring to see my perennials. Keeping fingers crossed they do well. I have also been "lurking" this site all year but I just signed up and this is my first post. I saved some daylilly seed and ballon flower and I have some packets (daisy, lavender, etc.) that I found in the store late in the year. But with the Holiday bustle I had forgotten about Wsowing until I saw this post. (thank you for reminding us) I am in southern Ohio and we have not had much cold weather yet....See MoreC Curry USA zone 6B
