The tree's tendency to grow crooked does not help its reputation as a source of usable lumber. Northern catalpa has been extensively cultivated in Ohio for over 200 years, and is now naturalized in urban and rural areas. Farmers introduced the rapidly growing northern catalpa to Ohio to produce large amounts of timber for fenceposts.
In late summer or autumn the fruit appear; they are siliques about 20–50 centimetres (8–20 in) long, full of small flat seeds, each with two thin wings to aid in wind dispersal. The large leaves and dense foliage of Catalpa species provide good shelter from rain and wind, making the trees an attractive habitat for many species of birds ...
×Chitalpa is an intergeneric hybrid flowering tree in the family Bignoniaceae.There are two major forms in North America, the 'Morning Cloud' a hybrid of desert willow (Chilopsis linearis) for desert hardiness and color, and northern catalpa (Catalpa speciosa), and the 'Pink Dawn' variety formed as a hybrid of desert willow and either yellow catalpa (Catalpa ovata) or northern catalpa ...
Jay Wilde . Trees with Spiky Seed Pods. If you've encountered some round, spiny balls under a tree or maybe still on the plant, and you're wondering what it could be, it's likely one of several ...
The fruit of the Southern Catalpa resembles bean pods. The fruit is a long, thin seed pod 20–40 cm long and 8–10 mm in diameter; it often stays attached to the tree during winter. The capsule contains numerous flat light brown seeds with two papery wings. Despite its appearance, it is not closely related to true beans.
Young plants and seeds are poisonous, causing nausea, muscle twitches, paralysis, and often death. [citation needed] Dicentra cucullaria: bleeding heart, Dutchman's breeches Papaveraceae: All parts of the plant contain neurotoxic alkaloids such as isoquinoline and cucullarine, which are known to be poisonous to cats, cattle, and humans.

Catalpa fargesii, the Chinese bean tree, is a species of tree in the family Bignoniaceae, native to China. Growing to about 25 m tall, it is a deciduous tree which produces abundant pink blossom in spring, followed by narrow brown beans-like fruit in the autumn. Some sources place the species as a synonym of Catalpa bungei. [1]
