Can you recommend a flowering evergreen shrub for part-shade, other than rhododendron or azalea?
Some good candidates for your needs are schip (pronounced "skip") laurel, compact mountain laurel, or compact Japanese andromeda. Alternatively, you could plant a yew and keep it clipped.
For information about schip laurel (Prunus laurocerasus ‘Schipkaensis') see the University of Connecticut's fact sheet. The Missouri Botanical garden provides descriptions of mountain laurel (Kalmia latifolia), Japanese andromeda (Pieris Japonica), and yew (Taxus).
Any of these plants should work well in your space.
Update: It's spring 2015 and the mountain laurels have taken quite a beating this year due to the long, cold winter and so are not looking their best as yet. Maybe they will come around. Hopefully next year they will fare better.
For tips on a variety of gardening topics, see our Plant Information Guides.
