Hi,
I'm at the other end of s.f bay, in Richmond. These are the most disese resistant roses in 3 local no-spray gardens, among a total of c. 400 different rose cultivars and species:
China
Archduke Charles
Fabvier (clean)
Tea
Mme. Berkeley (the most disease resistant garden rose in my garden)
Anna Olivier (very fragrant )
Mrs. Dudley Cross
Baronne H. Snoy
Rosette Delizy
Comtesse Emmeline de Guigne (starry satiny peachy blooms, turn to strawberry pink roses miraculously in summer)
Monsieur Tillier very clean and of all my Teas the most rapid growing, I bought a plant from a.r.e. in January and it is more than 3 feet tall by a greater width, it is in full bloom this week and very fragrant it is too.
Rosette Delizy very clean.
Clementina Carbonieri clean when mature.
Mrs. B.R. Cant
souvenir de Pierre Notting is nearly clean but it has an unsightly finish as does
Mlle. Franziska Kruger, though a lovely color.
mild to moderate p.m. when it rains:
Mme. Alfred Carriere
Mme. Lombard
Etoille de Lyon
Tea-Noisette
Lamarque (nearly spotlessly clean)
Crepescule (equally disesae resistant)
Celine Forestier all these 3 are very disease resistant
followed by
Reve d'Or'which gets a light covering of p.m. whenever it rains, but it is a great beauty and gets more applause than other roses in the same garden.
Alistair Stella Gray
Marachel Niel
was similar to reve d'or the firs year but this year it has shown no p.m. and it is still only c. 3 feet tall by the same width.
Mme. Alfred Carriere gets the most powdery mildew of all the Tea-Noisettes listed here, grown without being sprayed, still she blooms normally and it's a very pretty rosebush.
Noisette
Catos cluster' lush beautiful foliage
is as disease resistant as R. moschata, both are clean in my garden.
Cemetary Musk' from sacramento cemetary. simple five petaled blooms of a blush pink. long bloom season, still blooming in November.
Polyantha
all the forms of Mlle. Cecille Brunner, the spray form has the longest bloom cycles and best re-bloom, look for long feathery sepals.
Perle d'Or nearly as disease resistant
Borderor ditto
Marie Pavie also very good and easy to grow. Lovely scent.
Hybrid Perpetual
Grandmothers Hat some rust late in the year, but it is still blooming in November with the Tea roses.
Baronne Prevost
Mrs. John Laing
Frau Karl Druski
Damask and D.P.s
Autumn Damask
Ville de Bruxelles
Celsiana (takes my breath away)
Mme.Boll a bit more d.r. than J.C-M.B.
J. Cartier-M.B.
Bourbon
Boule de Neige some b.s. but not enough to bother me.
s.d.l.m. healthy but doesn't open in spring or autumn in cool weather.
Hybrid Tea
two early H.T.s that show a lot of Tea influence:
Mrs. Herbert Stevens (the climbing form can be grown self supporting as it is at the Berkeley Botanical Garden, it blooms in late February, as early as M.A.C..
Mme.Jules Bouche has the rapid rebloom of a Tea and is very clean here.
Hybrid Musk
Callisto a Pemberton beauty, yellow and very fragrant.
Cornelia
Darlows Enigma
Lavender Dream
Felicia
Pax (Luanne has a splendid Pax on rootstock from Pickerings that has a beautiful growth habit, c. 6 feet tall and self supporting it makes a wide arching vase shaped plant. rapid rebloom and nearly evergreen foliage in our climate. a visitor from Montisfont said it was the most beautiful plant of Pax they had ever seen.
Gallica:
Apothecary Rose
belle de Sultane
Alba
Alba Semi Plena
I nearly forgot Mermaid, I'm espaliering it in my backyard to keep it under control. nearly evergreen foliage and it blooms through early december.
borderline for p.m., usually covered lightly with it, but bloom normally
duchess de brabant
Lady Hillingdon
I grow mostly evergreen roses because they bloom so often and are so exquisite, the classes of Bourbon and H.P. have been more problemental, the pink and white roses of both those classes are more disease resistant on average than the red, locally.
I have gone so far to flirt with two modern roses for a disease resistant red: Sirens Keep, and William Shakespeare 2000, just playing footsie at this stage... I admit having a prejudice for antique roses.
Best wishes,
Luxrosa
