  • Chinese catalpa

    Catalpa ovata
    The Chinese catalpa thrives in Midwestern urban environments. It has showy blossoms that appear in the spring, followed by bean-like seed pods. This tree can withstand a range of soil types, including wet and dry conditions, which makes it useful in difficult sites such as moist low spots and dry sites with poor soils.
  • Chinese chestnut

  • Chinese juniper

    Juniperus chinensis
    Chinese juniper is a durable, adaptable evergreen tree or shrub that can bring year-round color, structure and screening to a dry, alkaline or windy site. A wide variety of cultivated varieties are available for garden and landscape use that range from trees to shrubs down to ground covers. Because they are quite salt-tolerant, they can be used near roads, driveways and sidewalks.
