Zucchini

The running joke in gardening: you'll have so much zucchini you'll start leaving bags on your neighbors' doorsteps. One plant can produce 6-10 pounds of fruit per week at peak season. Zucchini seeds germinate in under a week, the plants grow visibly day by day, and the first harvest comes just 45-55 days after planting. They're the confidence booster every new gardener needs. The challenge isn't growing them — it's using them all.
