Sweetgrass

Anthoxanthum nitens

Also Known As - Vanilla Grass,Holy Grass
Sweetgrass (Anthoxanthum nitens) is a low-growing, mat-forming grass native to Europe and Asia. It has distinctive, sweetly-scented foliage and airy plumes of flowers in late spring to midsummer. The leaves are long and narrow, reaching up to 12 inches in height, with a delicate, pale green color. Sweetgrass can adapt to most soil types as long as they are kept damp, which makes them hardy and easy to grow. When dried, the foliage and flowers give off an unmistakable sweet aroma, making them a popular choice in bouquets, fresh and dried arrangements, and potpourri.

watering

For sweetgrass, it is best to water frequently but lightly. Water when the top layer of soil is dry, which is usually every 7–10 days. When you water, give the plant just enough to moisten the soil, but avoid overwatering. Generally speaking, sweetgrass should be given about 1 inch of water per week.

sunlight

Sweetgrass (Anthoxanthum nitens) requires full sun throughout the day to thrive. It does best when it receives at least 6 hours of direct sunlight per day, with 8 hours or more being ideal. Additionally, Sweetgrass benefits from indirect light during the cooler parts of the day, such as the early morning and the late afternoon. This helps ensure that the plant receives all the light it needs in order for photosynthesis to occur.

pruning

Sweetgrass (Anthoxanthum nitens) should be pruned in late spring or early summer, when the plant is actively growing. Regular pruning of sweetgrass is important for maintaining its shape and keeping it healthy, as well as to remove any dead or diseased material. A good rule of thumb is to prune back any dead or dying leaves, spend and around 20-25% of the overall foliage. This amount of foliage removal will allow light to flow into the center of the plant, encouraging dense new growth.
