As other summer flowers fade away, roses step up in the fall, giving blooms into November. Here, with eucalyptus from the back yard.
When there are no presentable, cuttable scented flowers in the garden, I make bouquets of scented herbs. They may be lemony or fruity - as lemon balm, lemon verbena, apple mint, pineapple mint; or minty - spearmint, peppermint, chocolate mint; or various herbal scents such as fennel, rosemary, anise hyssop. A bit of rue, for its lovely flowers and leaves, might go into a bouquet with mint to cover the scent; with yarrow, not a scent I care for, I usually add a lot of lemon balm.
