The Meyer Lemon is actually a hybrid between a lemon and a mandarin orange. Citrus leaves have been used in various cuisines to infuse aroma into dishes.

Medicinal & Uses

Fruit is rich in Vitamin C. Leaves and peel produce essential oils used in aromatherapy, cleaning products, and flavoring.

Ecological Role

Provides nectar for various pollinators; serves as a host plant for the Giant Swallowtail butterfly caterpillar (Papilio cresphontes).
