The Ginkgo tree, also known as the maidenhair tree, is the oldest-existing tree species in the world. Its fan-shaped leaves are found in fossil records that go back 225 million years, which means its history dates back to the time of the dinosaurs.
The world's tallest-growing tree is the coast redwood (Sequoia sempervirens), which grows along the Pacific Coast of the United States, mainly in California. Interestingly enough, it's not the world's oldest-growing tree; that award goes to a bristlecone pine (Pinus aristata).
Bamboo is the fastest-growing woody plant in the world; it can grow 35 inches in a single day.
From a botanical standpoint, avocados and pumpkins are fruits, not vegetables, because they bear the plants' seeds. Rhubarb, on the other hand, is a vegetable.
Archaeologists have uncovered evidence that grapes were grown to make wine about 8,000 years ago in Mesopotamia (today's Iraq), although the ancient Egyptians were the first to record the process of making wine about 5,000 years ago.
