Answer: My first choice would be dwarf sweet box (Sarcococca hookeriana humilis). This modest evergreen shrub has tiny white flowers tucked between the axils of its shiny dark green leaves; you'd never notice them if it weren't for their intoxicating perfume. It's a shade-lover, perfect for the north side of the house. Other suggestions include Daphne odora (winter daphne), Itea (Sweetspire), Osmanthus heterophyllus (Holly-leaf osmanthus), and Skimmia.
Enjoy your fragrant garden!
