Often, gardeners don't give much thought to the aroma of the plants, but a fragrant plant can add a whole new dimension to the garden, making it a treat to the senses. Nothing is as invigorating as the scent of lavender or as peaceful as the sweet aroma of jasmine wafting through the air on a warm summer evening.
Brugmansia, also known as angel's trumpet because of the showy trumpet-shaped blooms, adds a tropical touch to the landscape. Although brugmansia is always sweet-scented, the best time to enjoy its aroma is just before nightfall. Brugmansia is hardy in temperate climates, primarily USDA Hardiness Zones 10 to 12.
Heliotrope (Heliotropium arborescens) grows as an annual in cooler climates but is hardy in USDA Hardiness Zones 10 to 11. Available in pale lavender, white and the familiar dark purple, heliotrope has a subtle, vanilla-like scent. Plant heliotrope where the plant can benefit from sunny morning, but protect it from hot afternoons that can burn the foliage.
Lavender, (Lavandula), is a familiar herb perennial in USDA Hardiness Zones 5-10. Because of its sweet scent, lavender is often dried and used in crafts, aromatherapy, and even to flavor jams, jellies or vinegars. Lavender loves dry weather and sunshine and is also suitable for container growing.
Short-lived lilac flowers make an appearance in early spring. The scent and blooms make lilac a favorite among flowering bushes. Visit an old homestead and you may see lilacs that have been there for more than a hundred years, a testament to the lilac's durability. Lilacs are hardy in USDA Hardiness Zones 3 to 7.
One jasmine bloom can be enough perfume the entire garden. The sweet blooms will draw butterflies and hummingbirds to the landscape. Jasmine is a moderately fast-growing, vining shrub that can grow up to 24 inches in a year. A tropical plant, USDA Hardiness Zones 9-11 are most favorable for jasmine.
