Engaging the sense of smell is a brilliant way of attracting anyone into a garden – especially youngsters. Some amazing scents will help capture their imaginations. Plant verbena (Aloysia citrodora), a wonderful evergreen shrub that smells of lemon sherbet, or chocolate cosmos (Cosmos atrosanguineus), with its crimson, long-stalked flowers that recall dark chocolate. And Mexican orange blossom (Choisya ternata) is an aromatic evergreen shrub that, to me, smells like Vicks Sinex. Or try basil, mint or the curry plant (Helichrysum italicum) to wow your young gardeners.
