Let me check my "Garden Gate" magazines and I'll get back with some suggestions later this aftermoon. BTW, do you want any siberian iris? I've been splitting and replanting and have a lot left over.
Sure! Your irises are one of the things I didn't manage to kill. :)
They seem to like it around TheSunRoom.
Whoops, sorry I didn't get back to you yesterday; kept finding articles to read in my Garden Gate :-)
How about a spreading "Prostrata" spruce (Picea pungens)? It is a gorgeous blue color, which would look good in Christmas decorations. Or there is always OB's favorite-Holly. Now you would need a male and a female plant to get the holly berries, but it is a evergreen. The biggest drawback to holly bushes is the leaves have sharp thorns, and they just become sharper over time.
And there is always the euonymus-E.fortunei (winter creeper euonymus) is a evergreen ground cover or low hedge, while E. kiautschovica (spreading euonymus) is a semi-evergreen shrub (to 10 feet) with conspicuous spring flowers. I'm not sure what semi-evergreen means...
Anyway, there is a lot of good stuff out there; I'll keep checking my magazines, I only got through about half of them last night.
