| Interesting these results from a mediterranean climate like mine with hot, dry summers, cool wet (sort of!) winters, and little rainfall throughout the year. I have gotten similar results--rugosas and numerous species/species crosses do extremely well here. In addition, my roses grafted onto multiflora and roses with a lot of multiflora in them as well as eglantines and spinosissimas also perform superbly. See the link below to read the discussion about how the trials have been conducted and the results. Here are the best performing roses: "Drought Tolerant Climbers Drought Tolerant Shrubs Drought Tolerant Rose Species Shrubs Melissa |

| Rugosa scabrosa is literally a weed in my garden with almost no supplementary water, but Roseraie de l'hay is sulky. Some on the forum have said rugosas don't like heat. Basically, I'm confused. |

| It gets plenty hot here in the summer, over 100 degrees f. is not uncommon, and rugosas seem to like it just fine. I'm pretty miserly with the water too. Only one of my rugosas is a poor performer, Mme Georges Bruant, and not surprisingly she has a tea parent, the real Mlle de Sombreuil (Mme Georges Bruant was produced in 1887 before Mlle de Sombreuil became confused in commerce). She takes after the tea part of her heritage in wanting lots of water and badly mildewing. So I think it depends on the rugosa. Those that are mostly rugosa, or that favor their rugosa genes, like leaner, sandier soils and are pretty drought tolerant. The ones that are crosses with less drought tolerant roses may perform more like the other rose(s) in the cross even if they have the outward appearance of a rugosa. Melissa |

| The article in the link is very interesting and demonstrates what a great change there has been in climate just since 1990. The famous green English lawn may become a nostalgic memory in the not too far-off future. Unfortunately most of the roses mentioned aren't of great interest to me and may not be the best from an aesthetic point of view. However, it's a very useful trial in that we may have to change from what we want to grow to what we CAN grow. Ingrid |
