When we’re planning landscapes, we think about structure, form, color, balance, but sometimes overlook another aspect that makes any garden delightful: scent.
Although scent is often associated with flowers, it can also come from other parts of the plant such as leaves and branches. Think of how aromatic a pine tree can be in the winter, or how fragrant herbs are when brushed against or crumbled in our hands. Scented geraniums release fragrance through the oils in their leaves. There are plants that release scent when touched, others that do so only at night, and still others when a breeze brushes through them. Many white or light colored flowers that are pollinated by moths are nocturnal – blooming only at night, and releasing their fragrance after the sun sets.
Chemically speaking, a plant’s fragrance comes from the essential oils that are produced when an acid and an alcohol are combined. It is the alcohol component that gives the flower or foliage its characteristic smell. These molecules, called esters, are often heavier than the surrounding air so they are typically found close to the ground.
Here are some fragrant options for your landscape to consider:
- Mock Orange – Beautiful, double-bloom white flowers appear against dark green leaves in early to mid-summer, emitting a delightful orange-like scent, even though they are not related to oranges.
- Star Jasmine – A climbing, woody evergreen, Star Jasmine smells sweet, smoky and a little spicy. A cross between ylang-ylang and true Jasmine.
- Lilac – This classic shrub is a favorite for it’s gorgeous clustered blooms that range in color from snow white to deep purple, and it’s heady, sweet scent.
- Gardenia – Stunning white flowers against deep, shiny green leaves make this shrub as beautiful as it is fragrant.
- Korean Spice Viburnum – This deciduous shrub produces large clusters of spicy-scented, pink flowers that fade to white. Bright red berries fade to black in fall. Foliage becomes red and burgundy in autumn.
- Clethra Sugartina – This summer flowering shrub produces fragrant, snow-white flower spikes that look stunning against its dark glossy foliage. It blooms even in shady areas and is tolerant to road salt.

- Scented Geranium (Pelargonium graveolens) – An annual with attractive blooms whose scent comes from the tiny glands at the base of the plant’s leaf hairs. Crushing the leaves releases the oil and scent, which, depending on the variety, can smell like apricot, lemon, mint, strawberry or apple.
