Some dwarf or baby bok choy varieties mature in 30 days or less. Bok choy is a cool-season crop that thrives in areas with milder winters and cooler summers.

Cilantro can be finicky because it’s highly sensitive to heat and stress. However, when planted in the right conditions, it grows rapidly, and the leaves are ready for harvest in approximately 25 days.
Cilantro grows well in USDA zones 3 to 11, but it bolts easily in hot weather. Therefore, provide it with some afternoon shade in warmer zones. It’s perfect for tacos, salsa, or anything that needs a citrusy herb kick.
13. Fenugreek Sprouts
Fenugreek seeds are more commonly used in spice blends, but the leaves are also edible. Fenugreek sprouts are aromatic and used in a lot of cuisines, including Indian, Middle Eastern, and North African.

Basil typically takes about 60–70 days to reach full maturity. But if you grow it as a microgreen, you can start harvesting the baby leaves in as little as 21–28 days.
Micro basil has a more intense, slightly sweeter taste than regular basil. It’s also more tender. It prefers warm weather and will grow as a perennial in USDA zones 9–11, and as an annual in all other zones. It also needs full sun and fertile soil. Great for garnishes, pesto, or infusing oils.
15. Zucchini
Zucchini takes about 50 to 60 days to grow from seed to fruit. But while you wait, you can harvest and eat the flowers.
Zucchini plants produce both male and female flowers on the same plant, but the male blossoms (found on long, thin stems without any fruit) appear first and can be harvested in under 30 days if the plant has enough sun and water. These edible flowers are a gourmet favorite, especially when stuffed or fried.

Chervil is a close relative of parsley. However, this delicate herb smells and tastes mildly like anise. It’s ready for light harvesting within a month.
