In my zone 5 garden, Corydalis has self-sown in a rock wall and down cracks in the side of a set of cement stairs...
The sun shining through the windows lights up the colors beautifully!
You can plant these little beauties liberally in beds and rock gardens and naturalize them in other undisturbed spaces.
All meadow rues offer height in a shade garden.
Some speedwells are low growing but most are upright with flower spires of blues, violets, pinks and whites.
Bright accents will make any blue/grey background plantings pop!
A lot of the best plant combinations in my yard have occurred without my conscious intervention.
Like a little black dress, some plants are classics and never go out of style.
Now that we have had our first frosts in the Midwest, I am thinking about what to plant next year.
In my Midwestern garden amsonia's yellow foliage (not shown in this picture) is a welcome accent in the late autumn landscape.
