Navel Orange

Citrus × sinensis 'Navel'

fruit

Washington Navel is the seedless eating orange that defined the California citrus industry. Large rounded fruit with the signature small secondary fruit (the navel) at the blossom end, an easy-peeling rind, and sweet richly flavored juice. The variety is parthenocarpic, meaning it produces fruit without pollination, which is the source of its seedlessness.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Marigolds: Roots release nematode-suppressing compounds that protect citrus feeder roots
• Lavender: Pollinator magnet that repels aphids and supports beneficial insects
• Basil: Aromatic foliage may confuse citrus leafminer and supports pollinators
• Comfrey: Deep mineral mining; chopped leaves return potassium to citrus roots

🌾 Harvest & storage

Washington Navel ripens November through January in most California regions, with fruit holding well on the tree into early spring. Pick when the fruit turns full orange and feels heavy for its size; navel oranges do not continue to sweeten after harvest. Twist gently or clip with pruners. Store at room temperature for a week or refrigerate up to a month.
