Northern Catalpa - A tree to consider for your landscape

Photos by Linda Langelo

Northern Catalpa, Catalpa speciosa are beautiful trees.  They flower later in spring to early summer usually May or June. The flowers are very striking.  They are white with purple markings. 

This tree has a spread of 20 to 40 feet and a height of 40 to 60.  One drawback to planting this tree is that fast growing trees tend to be weak wooded trees.  The Northern Catalpa in the picture is fairly close to the house.  Consider using this tree to shade the back yard or at least place it further away from the house.

But while in flower, this tree is spectacular.  The leaves are heart-shaped or cordate leaves.  In the fall of the year, you would have to rake the leaves so that they will not smother the turf.  The size of the leaves can be from 6 to 12 inches.  They are a little difficult to totally breakdown under the mower blades. 

Because these trees are fast-growing, people look to these trees to provide shade.  They grow in zones 4 through 8. 

The best features of this tree are as follows:

  • tolerates hot weather
  • drought tolerant
  • grows in a wide range of soils including alkaline soils
All of those features make this tree an asset to the landscape in hot, dry northern Colorado with our alkaline soils.

4-H Clover Garden

 Photos by Linda Langelo

These are pictures of the new 4-H Clover Garden in Sedgwick County Fairgrounds in northeast Colorado.  This garden is the only one of its kind.  This garden was made possible by Colorado Garden Show, Inc. funding.  The garden is to be used as an educational tool and when not being used as such it adds to the aesthetics of the fairgrounds. 

Each leaf represents the vision of 4-H philosophy come to life.  Each leaf of the clover is filled with plants or sculpture that represents that leaf.   At the moment we are waiting for the final sculpture.  When it arrives, I will add the final picture of the garden.  Stop by and see the garden, if you are in the area.
