The blue fruits on this tree are actually fleshy cones. Often used as a screen by planting in one or two fairly dense rows. Also useful as a background tree.  Can be a specimen tree.

Understory tree. Can be trimmed to keep sized as a shrub. Accent shrub or can be trained as a hedge.

Called pignut because pigs eat the nuts. Excellent specimen or shade tree in areas where its roots will not be disturbed.

There is a natural dwarf form that is associated with xeric uplands.  I makes a nice, low-growing shrub in casual gardens. Good as a background or hedge plant that also attracts wildlife. Rain gardens or bioswales.
