Botanically, tomatoes, avocados, cucumbers, peppers, pumpkins, and olives are fruits, while rhubarb is a vegetable. In the kitchen, however, most are treated as vegetables, used in savoury dishes rather than desserts. Knowing both perspectives helps gardeners and cooks understand how these plants grow, and how best to enjoy their flavours in recipes and harvests. Ah, the age-old question: is it a fruit or a vegetable? It’s one of those debates that has confused gardeners and chefs for years! While botanists and cooks often disagree, one thing is certain, knowing the difference can make you a more confident gardener and cook. Let’s break it down with some of the most commonly confused plants in our gardens.Is Tomato a Fruit or Vegetable?Botanically speaking, tomatoes are fruits. They develop from the flowering part of the tomato plant and contain seeds, which is the strict definition of a fruit. But in the kitchen, tomatoes often behave like vegetables, they’re used in savoury dishes, stir-fries, soups, and sauces rather than desserts. Even the U.S. Supreme Court weighed in back in 1893, ruling tomatoes should be classified as a vegetable for tax purposes. In short: science says fruit, cooking says vegetable.Is Avocado a Fruit or a Vegetable?Avocados are another sneaky one. Like tomatoes, avocados are technically fruits. They grow from the ovary of a flowering plant and have a single large seed inside. But in culinary terms, they act as vegetables, showing up in guacamole, salads, and toast spreads rather than sweet desserts. Fun fact: avocados are rich in healthy fats, making them a versatile and delicious addition to both raw and cooked dishes.Is Cucumber a Fruit or Vegetable?Cucumbers are often assumed to be vegetables because of their crunchy texture and savoury use in salads. But, botanically speaking, cucumbers are fruits. They develop from flowers and contain seeds. Despite this, their mild, refreshing flavour keeps them firmly in the vegetable section of most kitchens. They’re fantastic raw, in salads, or pickled for a tangy twist.Is Rhubarb a Fruit or Vegetable?Rhubarb is a bit of a rebel. Botanically, it’s a vegetable, since we eat the stalks and not the seeds or ovary. But in the kitchen, it behaves like a fruit, it’s sweetened and baked into pies, crumbles, and desserts. Just remember: the leaves are toxic, so stick to the stalks!Are Peppers a Fruit or Vegetable?Bell peppers, chilli peppers, and sweet peppers, these colourful garden staples are all fruits in botanical terms. Each develops from a flower and contains seeds. In the kitchen, however, they’re usually treated as vegetables, appearing in stir-fries, soups, and roasted dishes. Their versatility makes them a must-have in both gardens and pantries.Are Pumpkins a Fruit or Vegetable?Pumpkins are another culinary trickster, they’re fruits. They grow from flowering plants and contain seeds, ticking the botanical boxes. Yet in the kitchen, they straddle both worlds: you can roast them as a savoury side, or turn them into pies and desserts. Their tough texture makes them excellent for both hearty soups and sweet treats.Are Olives a Fruit or Vegetable?Olives are firmly fruits, coming from the olive tree and containing a single seed. Yet, like many other “savoury fruits,” we rarely eat them raw. Instead, they’re cured, pressed into olive oil, or added to salads and Mediterranean dishes. Despite their bitterness when raw, olives are a year-round staple with plenty of culinary flexibility.In the end, whether a plant is a fruit or vegetable depends on who you ask, the botanist or the cook. In the garden, knowing the botanical definition can help with planting, companion planting, and understanding growth cycles. In the kitchen, it’s all about taste and texture preferences, and how you want to enjoy your harvest.
