This is a sedge. Most Rhynchospora species are wind pollinated. The white bracts of this species attract insects. Can use as a groundcover in moist sites. Good in an informal savanna setting, rain garden or bioswale.

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.

Groundcover for dry sites. Clonal (forms small clumps of stems).It has deep red foliage in fall.

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.
