I have every rose on your list except Clio and am Zone 7 like you except it doesn't get as warm here in the summer I expect. I probably got most of mine from Pickering too. Expect roses in general to get at least a foot higher than Pickering suggests unless you are a pruner. I would give the Mosses 5X5 to be safe and the Gallicas, though 4X4 with moderate pruning would usually work. Chloris gets quite large. It is a long caned Alba rather different from the usual Alba growth(rather like Great Maidens Blush) but being totally thornless it is easy to place. I keep mine in a narrow slot about 5'wide by pegging it forward. It easily reaches 7'or more high. My Fürstin von Pless has been problematic-doesn't want to do a thing. It is a Hybrid Rugosa of course and spray drift can be a problem if you are planning on spraying. You need to account for that in spacing. Surpass Tout is one of my favorite Gallicas and as Olga said Jenny Duval will sucker vigorously...but it is a lovely rose. René d'Anjou is my best repeating Moss-better than Salat here. Mme de la Roche-Lambert gets Damask Perpetual crud here but has a beautiful spring bloom first. It repeats well but I dont spray with anything that keeps the crud truely at bay(sulfur) It is low and arching for me. Prince Napoléon is a very nice arching typical Bourbon. I suspect that it could get large. Mine has only been in the ground a couple of years from a band. You made some wonderful choices. As for the smaller size, Pickering grafted roses are generally smaller than the usual grafted #1 in the US because they are on multiflora. They are graded the same though, based on the number of canes. A 1 1/2 will be somewhat smaller and have fewer canes but every one I ever got that way did really well-by the end of the first season you could not tell. You will think they are puny but dont worry. patricia

I had the same problem. It two years before I finally got one blossom on my rhodie. This year is the first year I've finally got a lot of buds ready to burst. Mine faces the east side of my house and gets partial sun (but mostly shade). I fertilize it with Rhodie/Azalea food from Miracle Gro and then mulch it with pine needles after the Christmas wreath is spent. Just give it time and a little loving care and it should eventually give you flowers. Heather

the cherry laurel in my yard had tiny leaves, it was so deprived of nutrients. I cut that thing down! Any type of oil works, I use cannola cause that`s what`s in the house. It works for a huge number of insects, most are for some reason attracted to the color yellow. I really kind of gave up on controlling whitefly years ago, no matter what I`ve tried they have a couple of plants they like and they take over. Usually buy lady bugs in the spring and release those too. Tally HO!

Here's an apparent "SECRET TIP": if you're posting to a gardening advice forum - you would do well to indicate where in the world you are! Since, you know, a little bird told me some other parts of the world might experience different patterns of prolonged weather. (could be called something like climate, but I'm not really sure!) Mike Kincaid's videos are overall quite good but in the comments especially he sometimes slips in inaccurate advice, like saying 'Nova Zembla' is root rot resistant when in fact it has tested as moderately susceptible. Not likely to matter to you as much since your rhodo tags imply you are somewhere in Northern Europe. Where there are certainly better looking reds anyhow.
