There are many types of flowers, each with unique characteristics. Common categories include annuals, which complete their life cycle in one year, and perennials, which return year after year. Flowers can also be classified by their structure, such as single flowers with one bloom or cluster flowers that grow in groups. Another way to categorize flowers is by their habitat. Wildflowers grow naturally in the wild, while cultivated flowers are grown in gardens or farms. Additionally, flowers can be grouped by their color, size, and fragrance, making them diverse and appealing for various uses, from decoration to gardening.
