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.
