Crops which grow and mature within few weeks of their cultivation are called?

The crops which grow and mature within a few weeks of their cultivation are called ephemeral crops. These crops have a very short life cycle and complete their growth and development quickly. They typically require less time and effort to cultivate and can provide a quick harvest. Examples of ephemeral crops include lettuce, radishes, and spinach, which can be harvested in as little as 4-6 weeks after planting. Ephemeral crops are typically grown in cooler months or in regions with mild climates, as they can be sensitive to extreme heat and moisture. In contrast, annual crops complete their life cycle within a year, biennial crops take two years to mature, and perennial crops can continue to grow and produce for several years.
