Plant Species of the genus Catalpa

Information about this genus
Name: Catalpa
Cultivation: CULTIVATION: Catalpa make excellent specimen trees for parks and gardens and are also good for street planting. They adapt to cold and heat but should be sheltered from wind to protect the large leaves. A sunny site is best and the soil should be rich, moist and well drained. Young trees may require protection from late frosts and should be trained to a single trunk to prevent branching too close to the ground. The species are propagated from seed sown in autumn and the cultivars from softwood cuttings taken in late spring or early summer.
Description: This genus of 11 species of small to medium deciduous trees occurs in North America, Cuba and southwestern China. They are attractive trees with a somewhat tropical appearance due to their large long-stalked leaves. They bear showy upright panicles of 2 in (5 cm) long, bell-shaped flowers. The flowers are followed by hanging bean-like seed capsules that range up to 30 in (75 cm) in length. The genus name is a corruption of the North American Indian name for the plant.
