When you purchase a plant, it usually has not reached its mature size. It is important to know what size plant you need for your landscape planting. Select plants from the selection guide listing your desired plant height. Some parts of this selection guide list plants according to their height. These height categories are the averages of mature heights for the plants listed.
Plants grow at various rates.
Many people want to use fast-growing plants because they make their greatest contribution to the landscape in a short time. A plant's growth rate is partly controlled by its genetics. Plants grow faster when you give them proper care. A suggested planting distance is also listed to help you avoid placing your plants too close together. The guide also gives some suggested landscape uses for each plant on the list.
