Ube is purple yam, a root crop that is famously from the Philippines. It grows within 6 months upon planting. In a year, there are generally only 2 harvest seasons usually in June and December. Yam is different from potato, taro, or carrots. Though some may find it similar to them, yam is more starchy and creamy when cooked as desserts with milk. Most yams are grown in the lower hemisphere but their color varies depending on the climate of the country of origin. You can find white yams (mostly in the African region) and yellow or orange yams (mostly in the Southern American region) too.
