Meet the World's Fastest Growing Vegetables

Some vegetables take months to grow, while others seem to appear almost overnight. Fast-growing vegetables are exciting because gardeners do not have to wait very long to see results. Watching plants change quickly can make gardening even more fun.

Radishes are some of the fastest-growing vegetables in the garden. Many varieties can be ready to harvest in just 20 to 30 days. That means you could plant a radish seed and be eating crunchy radishes about a month later!

Lettuce is another fast grower. Baby lettuce leaves can often be picked in about 30 days, while full heads may take 45 to 60 days. Many gardeners harvest a few leaves at a time and let the plant keep growing.

Some herbs grow quickly too. Cilantro can begin producing leaves in about 3 to 4 weeks, and basil often grows large enough for harvesting in about 4 to 6 weeks. Green onions are also speedy growers and can often be harvested in about 30 to 60 days, depending on the variety.

Fast-growing vegetables help gardeners learn patience while still providing quick rewards. Even though plants do not grow overnight, some vegetables can surprise you with how quickly they develop from tiny seeds into foods you can enjoy.

Try It!

Think about something that grows or changes over time, like a plant, a pet, or even yourself. Which do you think grows faster: a radish, a lettuce plant, or a tomato plant?

Write down your guess and then research the answer with an adult. You might be surprised to learn that some vegetables can be ready to harvest in just a few weeks, while others take months to grow!

Fast-growing vegetables teach gardeners an important lesson: sometimes good things come sooner than we expect, but they still require patience and care.
