Your best bet might be to first lay down an erosion control blanket like
Curlex, through which you can then plant your groundcover. The blanket will
stabilize the soil until the roots can spread enough to do the job.

I recently removed an old Deck and am left with a 5' high ugly retaining
wall.
I have been filling it in with shale and then dirt and the final result
will be
a steep bank with about 45 degree slope. If I don't get some sort of root
system there, it will erode badly. Any suggestions for a good quick
growing
ground cover for a steep bank with a fair amount of sun.
