any chance you have fall pix to share ... ken

If you really don't like yellow, how about some white or cream colors to go with the pinks? They would blend well with the fall colors of your trees and give the eye a place to rest. Also several plants have a more lime green color that might blend well with the other pinks and green (hostas, coleus, etc.) . I agree, more purple and plum colors would be nice, but with the tree fall colors, try some creams and see if that goes better.

If you want grasses, one of my favorite drought tolerant plants is Pink Muhly grass that has (believe it or not) pink fronds that turn to cream colors in the fall. It is very pretty.

Ceanothus (CA lilac) is a plant that is also drought tolerant and has many different pink/purple colors in the spring but is green the rest of the year. They will fix nitrogen in the soil and like to be ignored as far as their care. They come in purple, blues some pinks and whites. Just having them off to the side (not mixed in with your roses as they don't appreciate the water nor fertilizer), would again provide some green against the other colors.

Rob333, I think that’s what I’ll gave to do. ;) I figure if I can choose very late blooming yellows, I can enjoy my pink and blue “English Garden” look for quite a while before having to surrender. And it will be nice to have a change at the end of the year, I think.

Ken, unfortunately (or perhaps fortunately? Lol) I do not. I should have, as I’ve been trying to document to know what to change and see the progression, but I missed photographing that stage.

Mustbnuts, thank you for all of the helpful suggestions! I finally got around to starting some creams/whites in that area, but they weren’t big enough to have an impact this past year. ‘David’ phlox, some oakleaf hydrangeas, and some ivory mums. I also have ‘Windermere,’ and ivory Austin, which I absolutely love. I’m wintersowing quite a few more perennials to hopefully fill in the gaps.

Muhly grass has been on my radar for quite some time! I grew up in Florida where we had it growing in the backyard wild. I love the stuff. In my zone, it’s sort of borderline hardy, but there is a native wild strain that I want to get ahold of, as I know it would do well.

You mentioned hostas and other chartreuse/green foliage. I do have quite a few hostas in an area off to the side! Most of them turned yellow this year, which was lovely. And I have lemon princess spirea and golden oregano interspersed throughout the garden, but I’m going to be propagating more this year as they didn’t quite make enough of an impact. Also my Solomon’s seal turns a lovely bright yellow. I want to incorporate it more.

If you don't want to embrace the contrast, consider planting once-blooming roses and roses with amazing hips and/or fall foliage. Spinosissima roses bloom briefly (except for hybrids like Stanwell Perpetual or Suzanne) and many turn yellow or red in autumn. Many of them also have beautiful glossy black hips! Very decorative. But you must be OK with thorns to grow them.

Asters look so lovely with roses in the Fall.

My taste is typically toward monochromatic or limited palette gardens (purples, blues and white), but fall is the time when a mad kaleidoscopic carnival of color is thrilling. Pink against fiery reds and oranges is perfectly acceptable. If it bothers you, but you want to keep those roses, here are a few options. You can cut all the roses and enjoy their last hurrah indoors. You can go with the flow of crazy mixes of color and add rich purples among the roses, or bring the flaming tree color to ground level in shrubs and perennials among the roses. the pink roses against the purplish toned burning bush could work well, and the burning bush could link to the tree colors. I don't know if in your climate there are trees or vines that have pink in the fall, but that might link the two. Try creating a board with all the colors and play with them in colored pencil, watercolor or crayons, or if you have photoshop, and see if you can find a combination that works for you.

While I am not a fan of burning bush (Euonymus alatus) If it is in an area like mine where it spreads invasively into wild areas, the native Euonymus atropurpureus might work. And I like the other advice suggested by noseometer of playing around with colors in nongarden media to help find pleasing combinations.

i also like the suggestions of Rob and mustbnuts to try colors that will work well with the current range such as white or blue-purple or buttercream/very pale yellow to help pull everything together.
