Located between the Divinity School and Garland Hall, this is the biggest catalpa tree in the arboretum, with a diameter of 111 cm (44 in.), height of 18 m (60 ft), and crown spread of 16 m (52 ft.).
Catalpas are noteworthy for their showy white flowers
in the spring, and long, thin fruits
that form in the summer and persist throughout the winter
. On this particular tree, there are numerous rows of sapsucker holes, made by a woodpecker that returns to the holes it pecks to lick the sap and any insects that are stuck in it. Sapsucker holes are not particular to catalpa trees - who knows why the bird chose this particlar tree for its holes?
