An almond is an oval-shaped nut that grows inside a hard shell. Almonds grow on almond trees.
Almonds are native to Mediterranean climates, particularly South Asia and the Middle East, and have spread to parts of North Africa, Southern Europe, and California. Almond trees flower in the spring, before the nuts are ready to harvest. While wild almonds are poisonous, the nut of the domesticated, sweet almond is delicious. We know the word almond comes from the Greek amygdalos, or "almond tree," but its origin beyond that is uncertain.
