Aralya, I'm not sure that our conditions are that similar, lol! My situation is VERY particular.
My garden is in a woodland area,on a hill that is about 600 meters above sea level, about a 20-minute drive from my home in our town. There is no running water out there, so plants must rely on rainfall after their first year in the ground for the most part. I harvest rain water and bring water in with my car,but I can only carry 200 liters per trip,so water is scarce.I have WAY too many roses and the garden is WAY too big for one middle-aged woman (me) to care for by herself, but I do my best.
We get little to no rain in the summer here; I have to consider myself lucky that we had one fairly good rain in July this year, though it certainly wasn't sufficient to irrigate my plants. Even now we are hoping and praying that soon it will start to rain-apparently the grape harvest is at risk at this point; there are grapes on the vines but they are too small and dry and need to be swollen by water in order to be worth something, so it's really bad.
In these conditions ,all I ask for is a good spring flush of bloom. In any case, once the heat hits for real ( this year, it arrived around mid-June) it's too miserable to be outdoors,and I only go out to my garden about once a week or so to water the new implants. It's so awful outside, and I feel so shriveled and burnt-out: how can I expect the roses to feel good, lol? In other words, I don't know that I can say much of value to you, other than some very generic things.Here they are.
In the bright light, pale and delicate colours wash out completely,so for the most part I have darkish pinks and purple-pinks. I want to introduce some of the deep ,deep reds and true violet purples,but since these colours tend to burn I'm thinking about how to provide some shade for them. In fact, I'm very much mulling over the entire question of shade,thinking of where to plant trees and such. The problem is that the south-western sun is just too strong and HOT and the days too long,and it seems to keep on getting worse . But there is a splendid view in that direction,which I don't want to block, so it's very tricky.
I don't have many pale, delicate-coloured roses ,but those that I do have I try to place with care so that they are right on a path, for example, so I can appreciate them up close. Ramblers and other once-bloomers are pretty reliable, but only the ones that bloom earlyish in rose season are really worthwhile.Teas seem to do well, though even they basically give a spring flush and then some bloom in autumn, if it rains enough. I'm beginning to think that perhaps some Noisettes and Chinas aren't really suitable for my garden; I think they may need summer irrigation in order to stay healthy. I've only recently started trying floribundas,so I don't know if they'll be able to handle this sort of situation. HTs don't seem like they'd be a good bet at all. Rugosas can't stand my soil or my climate at all.
