One Perennial that always stands out for it's fall color is the Geranium. Above is Johnson's Blue. The color is an outstanding brick red and it is still flowering above the foliage with bright blue-purple flowers.
Karmina (above) and Biokovo Geraniums also have the rich red fall color, but they have smaller leaves and mostly bloom in spring and early summer.
Purple Dome Aster is blooming very heavy right now, with nice purple clusters of Daisy-like flowers.
Red Shift Coreopsis is a new variety we have grown this year. It is a soft butter yellow with a deep red center (above) until the weather starts to cool off. The red gradually bleeds out until the flowers are completely red (below).

Kamschaticum Sedum did very well this summer in 2" pots. They cover pretty fast, have beautiful star shaped yellow flowers and excellent fall color. (see below)

English Ivy is an old standard that is evergreen and does well in part shade.
Ralph Shugert Vinca is a variegated variety with the typical blue, pinwheel flowers.

I just had to add this one: Jackmanii Clematis is blooming heavily right now. Clematis is a vine with stunning flowers that are generally (depending on variety) at least 4-5" across, and they will bloom profusely covering the entire plant.
Plumbago (Ceratostigma plumbagoides) is a very versatile perennial. It does well in full sun but will also thrive in shaded areas with some sun. It makes a beautiful taller groundcover. The bright blue flowers will bloom most of the summer and the foliage blazes bright red in the fall.
We recently started growing Midnight Rose Coral Bells and have been very impressed with the unique color patterns on the leaves. The leaves are very dark purple with bright pink specks.
Most of the Hostas are done blooming and starting to die back, but Guacamole is still shiny and green, and the large white blooms smell so sweet. (see below)

Bugbane (Cimicifuga ramosa 'Atropurpurea') also has a very sweet fragrance.
September Charm Anemone has large, soft pink flowers that are blooming heavy right now.
Chocolate Chip Ajuga is a nice groundcover for shaded areas. The leaves are narrow and compact and the flowers bloom purple on spikes in the spring.
Pink Ripple Thyme is still blooming sporadically, but the plants are incredible (see below). They could easily pass for a 2 gal plant

Hummelo Stachys is a Lamb's Ear that is quite a bit different. It has very showy flowers and smooth, medium green leaves. This is another that is thriving and totally dwarfing the little 1 gallon pot.

Yet another low, groundcover-type perennial that is doing exceptionally well this year: Georgia Blue Veronica
New England Aster is blooming now (photos above and below). It is a native species which shows in the flower color variations.
