Catalpa, Northern - - Catalpa speciosa


Large, tube, bell-shaped 2" white flowers are borne in 4"-8" long panicles in late spring. The crown is narrow, uneven or oval-shaped, with broad branches that curve upward. The very large, 6"-12", slightly heart-shaped, medium green leaves turn yellow-greenish or brown in fall. Bean-like seed capsules, 8"-20" long are green in color changing to brown and splitting open when ripe. It is tolerant of wet, dry, acid to alkaline soils, hot, dry environments, sun or partial shade, but prefers deep, moist soil. Because of the large leaves and seed pods, catalpa is not a tree to plant if a little annual "mess" is objectionable. Grows to 40'-60' with a 20-40' spread. (Zones 4-8)
