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.

The natural distribution in Florida is predominantly related to soil and drainage conditions.  If you provide them, it should grow successfully from Lake County northward. Specimen tree especially for moist sites.

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.
