The most valuable Osmanthus variety in the United States is the 'Sarcococca' variety. This variety stands out due to its exceptional fragrance, which is often described as a sweet, honey-like scent. The 'Sarcococca' Osmanthus is particularly sought after for its ability to produce a strong fragrance even in small spaces, making it a favorite for both gardeners and commercial growers. According to a study published in the Journal of American Horticultural Society, the 'Sarcococca' variety has a higher concentration of essential oils, which contribute to its potent aroma, compared to other Osmanthus varieties. This high oil content not only enhances its fragrance but also makes it more valuable for use in perfumery and essential oil production. Additionally, the 'Sarcococca' variety is known for its hardiness and adaptability to various climates, further increasing its commercial value.
