Macela is primarily grown in Mexico, Guatemala, and other parts of Central and South America. It is a hardy plant that thrives in warm, sunny climates and can grow up to 3 feet tall. It is typically cultivated in open fields, although it can also be grown in home gardens and small plots of land. The plant is propagated from seeds, which are sown directly into the soil during the spring or fall. The seeds typically germinate within 10 days and the plant reaches maturity within 3-4 months. After harvest, the plant is dried and the flowers are separated from the stems. Macela can be sourced from various suppliers, including local farmers, distributors, and online retailers. It is also commonly found in health food and herbal stores, as well as in traditional markets in Central and South America. When sourcing Macela, it is important to ensure that it is grown and harvested in a sustainable manner, without the use of synthetic pesticides or herbicides.
