For structure I think of grasses, Phormiums, tall spikes, mounds and,evergreens.
For the front Heucheras. Hostas, "grasses" like carex testacea, blue fescues, carex buchannii, stipa Tennuissima, elymus magellanicus, etc. Iris pallida Variegata with blue and cream leaves, ophiopogon nigrescens with black leaves.
Hebes with coloured evergreen foliage and Phormiums provide contrasf of shape. Grasses like miscanthus variegatus and Gold Bar add more height and grace.
Scent provided by Daphne's. Sarcoccoca. Witch hazels, the shrubby winter,honeysuckle, and philadelphus. skimmias have a scent too as well as berries. Choisya is another evergreen scented shrub.
Clematis newly moser is great on a shady or cooler wall or fence, honeysuckles provide scent and colour,pyracantha for coloured berries, spring flowers and evergreen foliage.
I think hydrangeas give wonderful unique colour and shape too
