This
beautiful ornamental has large heart shaped leaves that are almost tropical in
appearance. They can grow to 12
inches long and 8 inches wide, are thick and smooth on top and hairy on the
bottom. It has showy white to purplish flowers that grow in erect pyramidal
clusters at the ends of the twigs. The long seed pods can grow to 20 inches and
give it its often dubbed name: Indian Bean Tree.
Called
Catalpa by the Cherokees, the Latin speciosa was added by biologists to
indicate its ornamentality.
It is a
broad tree when grown in the open, distinctive with crooked trunk and
picturesque irregularity.
Normally
growing from 35 to 70 foot tall, with a trunk diameter of 10 to 20 inches, this
tree will grow almost anywhere and under most all conditions.
It is an undemanding tree and one of the easiest to sprout.
In its natural range in the Ohio Valley, trees have been known to grow to
100 feet and five feet in diameter.
A
deciduous tree, its leaves are purplish when young and have purplish veins on
their undersides, attracting honeybees. The leaves are light yellowish-green in
maturity.
Flowers
bloom in early summer and are followed in autumn by the long conspicuous
seedpods which mature as green capsules 10 to
20 inches long and about ½” thick.
The pods turn dark brown in winter, staying on the tree, and split open,
liberating their flat seeds in early spring.
Bark is rather thin, grayish and vertically scaled.
Its wood is course grained and soft. Not strong, but durable in contact
with the soil, it is most often used as fence posts in commercial application.
