My color scheme is always the same; pink, purple, blue, & white. My workhorse plants are always foliage-focused; persian shield, coleus, caladiums. For flowers, whatever grabs my eye, available seeds, wish I could find some heliotrope here. I also like to have some spots of red here'n'there. Occasionally a yellow flower sneaks in, but not usually unless they are sunflowers or pansies. I LOVE the combo of dark purple & pumpkin orange but I never garden with enough forethought to actually do an area of this. I think this combo needs to stand alone or not be at all. I also love purple & silvery blue. Like campanula & cabbage. Here's some pics of my various gardens & combos over the years 1 2 3 4 5 6 7 8 9 10 After moving to AL a few years ago, I finally have had time this year to start some gardens here, but nothing worth taking pics of yet...

From a designer's perspective, the best plant combinations involve a careful balance of contrasting and complimentary features. The 'contrast' part typically involves the use of plant shapes and foliage textures while the 'complimentary' aspect generally relates to colors as well as sharing similar growing conditions. In the combination above, the bold, heavy texture of the hydrangea foliage is offset by the lacier, more delicate Actaea foliage. You also have the spreading mass of the hydrangea in contrast to the more upright, clumping form of the Actaea. The grass (Carex) adds still another form and textural contrast, while the smaller, rounder and spreading form of the heuchera or epimedium provides yet another textural effect. The hosta in tj's example does the same. Much of the complimentary effect comes into play with the colors involved.......the deep maroon of the Actaea foliage compliments the deep green of the hydrangea and will accent the hydrangea as begins to turn into its fall colors. The heuchera picks up both of these colors, as does the painted fern or the epimedium as it puts out its new spring growth. And of course, all these plants enjoy similar growing conditions as well. Because flowers are such a transitory aspect of a garden design, I tend to place less emphasis on combining specific flower types than I do on the foliage, but the above plants do offer a very nice combined flowering effect as well - the shape of the hydrangea blossoms is somewhat repeated in the spikes of the Actaea, plus the coloring of the coloring of the hydrangea flowers as they age will pick up the pinkish tones of the Actaea as well. And the heuchera or epimedium will offer an early and very delicate flower effect, repeated later by the hostas. IMO, the best combinations involve at least three different plants and often, more. Less than that and you do not achieve enough contrast and compliment to make the combination really effective.

Going through your list, I really love caryopteris, I grow it with rudbeckia and coreopsis verticillata and ornamental grasses. I treat it as a sub-shrub sort of like lavender. It stays in the background until it blooms in late summer/early fall. Then it takes center stage. I have 'Longwood Blue'. It hasn't gotten tall for me (it's listed at 4 feet) because I prune about a third to a half off each spring. Kerria japonica is a love/hate shrub for me. I planted it because I had an impossibly shady dry site that needed something. I eventually moved it out to a place under trees by the driveway in rock and gravel. It explodes with color in the spring which is why I keep it. I guess I should give it more respect given its ability to flower in almost full shade. It lives comfortably at the end of a Viburnum border. Any blue flowering spring bulb like grape hyacinth, crocus or Phlox diveracata would complement it. I have both roses you mentioned, Julia Child and Ebb Tide. Rose combinations are almost a separate topic but any of the perennial geraniums in blue tones for Julia work well ('Rozanne' comes to mind) along with lower growing Veronicas like 'Goodness Grows' and Salvias like 'Caradonna' and catmints like 'Blue Wonder'. For Ebb Tide Coreopsis 'Moonbeam' or any dwarf coreopsis would work well. Perhaps a daylily like Stella d'Oro or Happy Returns. Mine were planted in a new bed last season and so far I only have some dwarf coreopsis and salvias but hope to add more perennials this spring. Buddleia is another love/hate shrub for me, I have 'Black Knight' which gets huge so it is sits in a corner of two fence lines. Actually the rugosa rose 'Hansa' is next to it so they fight it out. The purple and magenta combination is kind of cool though. Cameron's photo is stunning, there are so many new dwarf varieties that would be worth trying. Calycanthus florida is one of my favorite shade shrubs. I have 'Athens' by the front door with Autumn fern, Lady fern, asian ginger, Loropetalum, Sarcococca, Cornus alba, Phlox divaricata, and various hostas. If you need more information or inspiration I suggest checking your library for the following books which have been helpful to me: "The Well-Designed Mixed Garden" by Tracy DiSabato-Aust "Rose Companions" by Stephen Scanniello "Perennial Combinations" by C. Colston Burrell

Hmmmm, our DS, DDIL, & the grands are here for a week. They've all walked down this afternoon for an ice cream while the pork smokes. We were going to make sandwiches but I'll bet the grands would LOVE a huge platter of nachos for dinner tonight! It's great to be a grandparent...you can feed the g-kids anything & not have to worry about nutritional balance!! Well, at least for a week. :( Were going to serve chips & salsa with the pulled pork sandwiches...easy to change everything to nachos. Done. Thanks, Duane!
