Large tree north of the Memorial Union parking ramp.
Native to Iowa, this
tree has a range from Massachusetts to Minnesota, south to northern Florida
and Texas, preferring the fertile, moist, well-drained soils of bottomlands
and lower slopes. The fruit is a round nut in a hard, corrugated shell.
The shell is surrounded by a thick, slightly hairy, semi-fleshy husk which
is yellow-green, turning black. Walnut trees are rarely planted as lawn
trees-they require exacting soil conditions, are subject to wind and ice
damage, produce messy fruit and the toxic substance from their leaves may
kill some ornamentals in the vicinity.
