Hardy Catalpa (catalpa Speciosa)




Distinguishing characters: The tree may be told by its *fruit*, which

hang in long slender pods all winter. The leaf-scars appear on the

stem in whorls of three and rarely opposite each other.



Form and size: The catalpa has a short, thick and twisted trunk with an

irregular head.



Range: Central and eastern United States.









Soil and location: It grows naturally on low bottom-lands but will also

do well in poor, dry soils.



Enemies: Practically free from disease and insects.



Value for planting: The catalpa grows very rapidly and is cultivated in

parks for ornament and in groves for commercial purposes. The _hardy

catalpa_ is preferable to the _common catalpa_ for planting.



Commercial value: The wood is extremely durable in contact with the soil

and is consequently used for posts and railroad ties.



Other characters: The _flowers_, which appear in late June and early

July, are large, white and very showy.



Other common names: _Indian bean_; _western catalpa_.



Comparisons: The _white flowering dogwood_ (_Cornus florida_) is a small

tree which also has its leaves in whorls of three or sometimes

opposite. It can be readily told from other trees, however, by the

small square plates into which the outer bark on the trunk divides

itself, see Fig. 85, and by the characteristic drooping character of

its branches. It is one of the most common plants in our eastern

deciduous forests. It is extremely beautiful both in the spring and

in the fall and is frequently planted for ornament. There are many

varieties of dogwood in common use.
