Single stems refer to plants that grow from a single main trunk or stalk, which supports the leaves and flowers. This growth pattern is common in many types of trees and some herbaceous plants. The single stem allows for a clear structure, making it easier for the plant to reach sunlight and grow tall. In gardening and landscaping, single-stem plants are often preferred for their aesthetic appeal and simplicity. They can be used as focal points in a garden or as part of a larger design. Examples of single-stem plants include maple trees and sunflowers.
