I noticed I've made some bad decisions in regards to grouping plants for color and texture contrast when the plants aren't in bloom.

So I'm curious to hear what some of your favorite plant groupings are whether on purpose or by chance.

By chance:
Rose Glow Barberry, Birchleaf Spirea and Dappled Willow. Although I planted the spirea for fall color its nice rich green color and formal habit look great to tie in the color and contrast of the other plants.

On purpose:
Blue Shadow Fothergilla, Ruby Spice Clethra and Georgia Peach Coral Bells. Again nothing is actually in bloom or sporting fall color but the texture and color contrast looks fantastic between these plants everything else is just an added bonus as the season progresses.

Thriller: Colocasia esculenta 'Mojito'
Filler: Coleus 'ColorBlaze®Royal Glissade®'
Spiller: Variegated spider plant

Someone said the basic plan for an appealing garden requires variation in size, form and texture. A small conical conifer (dwarf Alberta Spruce), an azalea and a couple of large-leafed hosta make a beautiful, low-maintenance display. The flowers are nice, but not essential.

Someone posted pictures of a dwarf Japanese Maple with blue hosta beneath it. The contrast was breathtaking.

I've been buying Siberian Iris lately. SI provide an upright form with spear-shaped foliage which maintains its beauty all season after flowering. It combines well with any low-growing plant or something with large oval foliage. Or just an oval rock.
