Winter plants

From Plant Life: Growing a Garden in the Pacific Northwest by Valerie Easton.

Sturdy evergreens to fill in the mid-layer:

• magnolia grandiflora 'victoria' - broad, glossy green leaves, backed with copper fuzz - good for vases and wreaths
• daphne odora 'marginata' - sweetly perfumed
• viburnum davidii - leather-leaved, blue fruited
• sasa veitchii - little running bamboo with tawny trim
  
• osmanthus heterophyllus 'goshiki' - gold-splotched leaves
• other mahonias
  
• callicarpa 'beautyberry' - metallic lavender berries
• pernettya mucronata - small evergreen w/winter fruits of pink, red, white
• witch hazels
• prunus subhirtella 'autumnalis' - winter-flowering cherry

other suggestions (for enjoying garden throughout winter):

• "tall cedar fence w/a row of black bamboo in front, pruned up to reveal the notched black canes, is a stunning, year-round screen than provides plenty of verticality, takes up very little space on the ground, and enlivens the garden with its lovely sway and rustle."
• plant fragrant treasures along pathways or in pots by the front door
• winter-blooming iris (I. unguicularis), hellebores, vanillal-scented sarcococca - add the surprise of flowers on bleak days
• sasanqua camellia espaliered by the front door that opens shell-pink flowers in mid-nov and often last through christmas
