Flowers are a treat for the eyes. Cut flowers brighten up any room, and outdoor plants add beauty and value to a landscape. Many flowers offer even more than a feast for the eyes, however: They are pleasantly scented as well. Flowers with a strong fragrance can add another, welcome dimension to your garden. In fact, many home gardeners carefully choose plants for just that reason, and plant them near a window or porch where their scent can be fully enjoyed.
Tuberose (Polianthes tuberose)
The tuberose is a bulb flower that is known for its strong scent, according to Country Living. It is a tender bulb, so it is only hardy to U.S. Department of Agriculture (USDA) zone 8. In colder climates, the bulb should be dug up before cold weather arrives. This fragrant flower has tall stems lined with delicate white blooms.
Peony (Paeonia spp)
Peonies are perennials known for their large, heavily ruffled, strongly scented flowers. The flowers, which bloom in late spring, have a fresh, citrusy scent. These plants grow best in USDA zones 3 through 8, making them a good choice for temperate climate gardeners who want a showy but fragrant flower.
Night-Blooming Jasmine (Cestrum nocturnum)
This jasmine is distinctive for the fact that it is most fragrant at night, allowing the home gardener who is away from home during the day to enjoy the nighttime fragrance. The small, white and yellow, tube-shaped flowers are so strongly scented that they emit their fragrance up to 20 feet away on still, warm summer nights. This plant blooms all summer long and will grow in containers, but it is only hardy to UDSA zone 8, according to Country Living.
Hyacinth (Hyacinthus orientalis)
This bulb plant is one of the first to bloom each spring. The hyacinth is a perennial that is related to lilies and features a short stalk (less than a foot tall) covered with small, brightly colored flowers. Hyacinths have a strong, pleasing fragrance and are hardy in USDA zones 3 through 9, according to Floridata. They are often planted in containers with other spring flowers and placed indoors or on porches so as to better to enjoy their fragrance and small stature.
