Hawaii's biggest cash crops are pineapples and macadamia nuts. Hawaii's weather is perfect for tropical fruits like papaya, bananas and mangoes to grow in abundance.
Hawaii is well-known for growing exotic fruits, but many other fruits and vegetables are also grown in Hawaii. Yams are difficult to grow on the mainland but they thrive in Hawaii. Yams must be kept above 68 degrees Fahrenheit in order to grow properly, so Hawaii's tropical climate provides optimal growing conditions. Other less common vegetables are grown in Hawaii, including taro, watercress and kai choy. More well-known vegetables such as broccoli, tomatoes and potatoes are also grown there.
Hawaii is home to over 700 coffee farms and is the only state in America that produces coffee beans. Kona coffee is one of the most popular brands of coffee that Hawaii produces. It is considered a delicacy among both natives of Hawaii and tourists because the beans are grown and harvested on the slopes of Hualalai and Mauna Loa.
Sugarcane was one of Hawaii's biggest cash crops for most of the 20th century. It is still a popular crop, but many sugar mills have closed down because of how sugar is harvested. Most of Hawaii's sugar is now processed and sold in California.
