The orange blossom is the fragrant flower of the Citrus sinensis tree, also known as the sweet orange. It is the state flower of Florida and has long been associated with good fortune, often included in bridal bouquets.

Orange blossoms have numerous uses:

The flowers are used to make orange blossom essence, an important component in perfumes
Orange blossom petals can be made into a delicately citrus-scented “orange blossom water” or “orange flower water,” used in French and Middle Eastern cuisines, especially in desserts and baked goods.

In Spain, fallen blossoms are dried and used to make orange tea
Orange blossom honey (or citrus honey) is obtained by placing beehives in citrus groves while the trees bloom, allowing bees to pollinate seeded citrus varieties

The orange blossom has a strong scent with citrus notes and sweet, soapy undertones. It is an evergreen plant with dark green, oval leaves and can grow up to 20-30 feet tall. Orange trees are commonly used for ornamental purposes, especially in the Mediterranean region, where they have historically been valued for their fragrance and beauty.
