Some flowering plants can fill a garden with surprisingly familiar scents. Chocolate cosmos and chocolate vine are known for chocolate-like fragrances, while vanilla orchid offers a sweet, delicate aroma. Heliotrope can smell like vanilla or cherry pie, and scented geraniums release fresh citrus notes. Certain jasmine varieties can also have citrus-like fragrances. These plants can add colour, fragrance and an unusual sensory experience to balconies, patios and gardens.
