What is the difference between a Cleveland pear tree and a Cleveland Select pear tree?

The Cleveland pear tree and the Cleveland Select pear tree are both cultivars of the Callery pear (Pyrus calleryana), but they differ primarily in their growth habits and features. The Cleveland pear is known for its upright, columnar growth and dense foliage, while the Cleveland Select variety is also upright but tends to have a slightly broader canopy and better branching structure. Additionally, the Cleveland Select is often preferred for its resistance to common diseases and pests, making it a more reliable choice for urban landscaping. Both trees produce showy white flowers in spring, but the Cleveland Select typically exhibits improved ornamental characteristics.
