Bitter Orange is antiseptic, anti-inflammatory, immune boosting, and high in antioxidant content. The fragrant yellowish-white flowers are used in soaps, perfumes, and essential oils (Bitter Orange is the source for pettigrain essential oil). Bitter Orange has strong resistance to disease and pests, and can withstand temperatures below freezing for short periods. It’s also self-pollinating, which means that only one tree is needed in order to fruit. The seedlings are about 5 inches tall. .
