I live in southern Ohio . I have an area about 12 ft by 5 ft . I want mounding low growing perennials that need very little attention . I like foliage of different colors including reds and purples but do not like the look of dying flowers. HELP HELP . I have look at so many plants its making me nauseous . SOME I like are : sedum ,moss verbena , Euphorbia , purple shamrocks . I DONT KNOW what colors go together . I need a plan . Any ideas would be so appreciated .
I can't help on the design, nor on choice of plants as my climate (UK) is very different from yours.
I can tell you what we did in part of our garden and it might help. We have an area by a pergola seat and we planted lots of mounding, ground cover plants around it. We didn't think too much about it - we were fairly random in our planting and it looks lovely. Plants we used (which might not be suitable for your climate) include:
Creeping Thyme (comes in lots of colours)
Creeping Phlox
Rock Rose (Heliathemum)
Roman Chamomile (looks a bit messy in winter so you might not like this)
Dianthus (there are lots of varieties, but I used mainly the ground covers)
EDIT: Another that we've purchased seeds for is Erigeron karvinskiannus 'profusion'. If you like daisies then this sounds like a good choice. An abundance of daisy like flower from May to November (UK climate - so essentially the whole season). No dead heading needed. I sounds as if it'll spread over large areas if you let it.

The best ground cover plants spread readily to cover lots of ground without becoming unruly. These 33 plants are vigorous but controllable ground covers.

If you want height in some areas I love the combination of Cone Flower (Echniacia), Black Eyed Susan and Blanket Flowers. They benefit from a bit of deadheading, but the flowers last a while so it's very little work.
