Their radiant white petals contrast beautifully with the tree’s glossy, dark green leaves, offering a visual spectacle that’s truly a sight to behold. The flower is particularly revered in perfumery, used to create floral waters and essential oils.

The distinctive trifoliate leaves, which fold up at night and open during the day, add to the flower’s allure.

Oxalis is an example of nature’s tenacity. While some gardeners view it as an invasive weed, others love it for its vibrant blooms and ground-covering ability.
