Hierochlöe odorata


plant overview
vanilla flavored and scented sweetgrass

Sweetgrass, also known as manna grass, holy grass, Mary’s grass and vanilla grass, is a robust perennial plant in the “true grass” family that is native to North America and Europe. Because woven braids of this grass are traditionally burned as smudge or offering in Native American ceremonies, it also called Seneca grass. The botanical name of this plant literally translates to “holy fragrant grass” and aptly describes the fresh, sweet smell when the stalks are cut. The dried herb, which owes its flavor and aroma to the presence of coumarin, is used to make tea and to flavor other beverages.

A Bit of Botany
a little botanical information on sweetgrass

Hierochloe odorata is a very hardy perennial of the Poaceae family.

Sweetgrass, as it is commonly known, has leaves that do not have rigid stems; therefore their height stays at around 8 inches. The leaves grow outward horizontally about 3 1/4 feet or even more by late in the summer. The leaves are without hairs. The underside too is hairless and also shiny. Just below the soil surface the bases of the leaves are broad and white. Though in the wild, the bases of the leaves are frequently purple-red colored; this indicates a phosphorus-deficient soil.

Cultivation & Harvesting
considerations for growing and harvesting sweetgrass

Sweetgrass grows on wet banks in cool to temperate climates. Since the plant has an aggressive root system it can help stabilize banks.

Prefers a damp position in a rich soil. However sweetgrass succeeds in most soils, including considerably drier conditions.

Sweetgrass is easily grown by dividing the plants in spring or summer. Divisions can be planted in the desired garden location. Sweetgrass will have mixed results if grown by seed. germination in 2 weeks has been reported, with more difficult or longer germination by other accounts also resulting in weak-rooted plants.

Sweetgrass leaves are harvested in the summer. There are several varieties of sweetgrass: there is a regular strain that can be harvested once or twice a year; and a naturally occurring polyploid strain, which can be harvested up to five times a year, since it is much faster growing. The grass is cut and usually braided to dry.
