Flora of Indiana (1940) by Charles C. Deam
This is generally a small tree, 3-8 inches in diameter, larger ones are rare. The largest redbud I ever saw was located on the Dicksburg Hills in Knox County. It was more than 2 feet in diameter at breast height. When I reported this tree to Prof. H. C. Cowles of Chicago University, he doubted the identity of the species or the measurements and made a trip to the tree and verified my measurement. It is found in woodland throughout the state, being most abundant in the southern half and infrequent to rare in the northern counties. Its preferred habitat is wooded ravines and banks of streams. At maturity the leaves are glabrous on both surfaces with a few hairs in the axils of the veins beneath or are more or less pubescent on the lower surface. The glabrous form has been named forma glabrifolia Fern. (Rhodora 38: 234. 1936).
Indiana Coefficient of Conservatism: C = 3

Deam (1932): In one locality it was known as the fish blossom because the larger fish spawn when this tree is in flower. The redbud is usually a tree 1-1.5 dm. in diameter and 5-10 m. high. It is of no economic importance and is classed as a weed tree in the woodlot and should be removed. It is frequently recommended for ornamental planting. It prefers a rich moist soil, and is shade enduring, although it succeeds best in the open or in a partial shade.
