Shrubs vs. Trees: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on April 15, 2024
Shrubs are small to medium-sized woody plants with multiple stems, while trees are large, single-stemmed plants with a distinct trunk.
Key Differences
Shrubs are characterized by their multiple stems and shorter height, typically under 6 meters (20 feet), which allows them to occupy the understorey of forests or form thickets in open areas. Trees, on the other hand, grow taller than shrubs, usually exceeding 6 meters in height, with a single main stem or trunk that supports a distinct crown of foliage. This difference in structure reflects their roles in various ecosystems, with shrubs often providing understorey habitat and food for wildlife, while trees form the overstorey, offering shade and habitat for different species.
Shrubs tend to have a bushy appearance due to their multiple stems that grow from the base, making them dense and often used for privacy hedges or decorative landscaping. Trees usually have a clear trunk for some height above the ground before branching out, making them prominent landscape features used for shade, windbreaks, and aesthetic purposes. The growth habit of shrubs and trees affects their use in landscaping and their ecological roles, with shrubs filling spaces between the ground and taller trees, and trees providing a canopy for understorey plants and animals.
The life span of shrubs and trees can also differ significantly, with many shrubs living for a few decades while trees can live for hundreds or even thousands of years. This longevity of trees contributes to their role in carbon sequestration and as long-standing components of their ecosystems. Shrubs, with their shorter life spans, often colonize disturbed or transitional areas quickly, playing a crucial role in ecosystem succession and recovery.
Shrubs typically require less space to grow than trees, making them suitable for smaller gardens and landscapes where they can provide color, texture, and structure without the space requirements of large trees. Trees, because of their size and longevity, are often considered investments in a landscape, requiring more space to grow but providing significant benefits in terms of shade, air purification, and habitat over a longer period.
Shrubs and trees differ in their reproductive strategies as well, with some shrubs able to propagate easily from cuttings or sprouting from the base after being cut down, allowing them to spread or recover from damage more readily. Trees may rely on seed dispersal for propagation, with their seeds often adapted to travel far from the parent plant, aiding in the spread of the species across larger areas. This distinction highlights the adaptability of shrubs in various environments and the role of trees in forest expansion and diversity.
