【Abstract】In nature, many plants can produce beautiful and fragrant flowers that are charming and delightful. However, some plants can emit fragrance even without blooming. For example, the camphor tree exudes a rich aroma with a balanced intensity, while the lemon tree, belonging to the citrus genus, emits a refreshing scent throughout its entirety, promoting a sense of joy and relaxation.
Most flowering plants emit aromatic scents that intoxicate the senses with their sweet fragrance. However, apart from flowers, some plants inherently possess their own fragrance, akin to having a “natural scent.” Even without blooming, these plants can still captivate attention with their appealing aroma.
- Camphor Tree
The camphor tree is a primary species for greening in many regions. It is commonly planted as roadside trees, lining the streets with neatly arranged camphor trees whose large crowns provide dense shade, forming unique scenic views within cities. The camphor tree exudes a rich aroma, with its fragrance being well-balanced, creating a very pleasant sensation. The scent of the camphor tree revitalizes the air. Additionally, this fragrance possesses significant properties such as corrosion resistance and insect repellence.
- Fragrant Olive
The branches and leaves of the fragrant olive emit a subtle fragrance, which gives a very refreshing sensation and is harmless to the human body, making it a favorite among many people. The foliage of the fragrant olive is a vibrant green throughout, with small leaves arranged neatly on either side of the leaf stalk, resembling feathers in their orderly formation. Fragrant olive plants are suitable for landscaping and greening gardens. With their petite stature, they are also ideal for potted cultivation, adorning indoor spaces or balconies
- Lemon Tree
The lemon tree, belonging to the citrus genus, emits a refreshing fragrance from its foliage. This aroma differs from floral scents, imparting a cool sensation.

Lemon trees can be planted in gardens, parks, and scenic areas. They are also suitable for courtyard cultivation, while potted lemon trees can be placed indoors as well.

- Golden Willow
The golden willow, also known as the colorful-leaved tree, is another plant that naturally emits its own fragrance. Its foliage appears in shades of yellow-green or golden, earning it the nickname “thousand-layer gold.” Due to its unique characteristic, the golden willow contains special aromatic compounds, allowing its branches and leaves to be distilled into valuable essential oils. In landscape greening, the golden willow is extensively planted in the southern regions of China. It can be used for both roadside greening and afforestation, as well as for household potted plants.
