Fragrance is another important feature of a romantic garden. The scent of plants can invites strolling. Heliotrope bears brilliant, almost violet blue flowers and a romantic, vanilla scent. Dianthus 'Magic Charms' wafts spicy-sweet. Violets signify faithfulness and Viola odorata is the violet of song and story.
Irises are a natural component of the romantic garden.
Their clean, sweet, grape-like smell and beautiful colors add to the mood. Grow them in clumps or along borders for maximum impact. Peonies are truly heirloom plants. Leave them undisturbed, divide only occasionally, and enjoy them for years. Friends speak of their grandmothers' peonies that have been thirty years or more in the same spot and have grown to enormous sizes.
