Whatever you do NEVER plant Bishop's weed (Aegopodium podagraria)!!!! Vinca
is also a real threat, and it has moved into natural vegetation in this area.

A good groundcover for a steep slope in the Pacific Coast states are
Pacific Coast irises, both species and their many and beautiful hybrids.
They don't "spread" but they quickly make large, weed-suppressing clumps.
Many are evergreen, too. They are drought tolerant and can be interplanted
with bulbs. And don't forget penstemons (the low kinds, not the big border
hybrids); many are open enough that bulbs can grow up through them, and
brodiaeas coming up through P. rupicola are a classic combination.
