Scientific Classification

• Redbuds are scientifically classified in the Cercis genus and are members of the Fabaceae family of flowering plants, which include beans and legumes. There are over 20 species of redbud trees, the most common of which are the Eastern redbud (Cercis canadensis), the Judas tree (Cercis siliquastrum) and the Western redbud (Cercis occidentalis), all of which are closely related and have similar growth habits.
  
  

Landscape Use

• Redbud trees are commonly classified as an ornamental tree for landscape use. Their colorful flowers and fast growth rate make them a popular choice for home landscapes, according to the University of Georgia. In addition to their spring bloom, redbuds are native plants that have few pest and disease problems and they are highly drought resistant, making them easy to care for once established in your landscape.
  
  

Size

• Redbud trees are classified as flowering shrubs or small flowering trees due to their size, according to horticulturalists at Clemson University. Redbud trees grow between 20 and 30 feet tall and have a mature spread of 35 feet wide. However, the tree can also develop as a multi-trunked shrub if not pruned to encourage a strong central leader. The trees are short-lived in home landscapes and only live to be 25 years old.
  
  

Culture

• Redbud trees grow best in full sunlight with moist, well-drained soils rich in organic matter. The trees will easily grow in shaded areas in your landscape, but the spring inflorescence will be less intense. Ensure that the seedling that you plant in your landscape is a variety of redbud native to your region.
