Each stem has soft, fleshy green flanges running longitudinally down its length. When winter weather brings ice, the stems exude water that freezes into fascinating shapes, hence its common name frostweed. Background plant in a wildflower garden. Also useful as a mass planting along a forest edge. This plant is best used in informal settings and does well if allowed to naturalize.

The wood is noted as being very strong, hence the common name "ironwood" Does not do well much south of its natural range. Small specimen tree. Also good as an understory tree. While rarely grown, this plant is very worth of use in the landscape.

Fragrant. Evergreen screen, evergreen shrub to small tree.

Similar in general appearance to St. Augustine grass. To look nice as a turf grass, seashore paspalum requires water and fertilizer and needs frequent mowing. High tolerance for heat and salt and will tolerate some shade. Tolerates some traffic and can recover quickly from moderate wear during spring and summer, but not suited to heavy uses such as ball fields. There is question on how appropriate it is to consider the cultivated varieties native. The range in Florida is essentially the sandy coastal areas.  A few other herbarium specimens appear to have been gathered from disturbed areas.  Given that this species is being used as a turf grass, we can expect it to occasionally occur outside of its historic settings. Used as a turf grass or in a wet meadow.

The range of this species is primarily the coastal plain from Texas to North Carolina. A second subspecies (subsp. greenmanii) occurs in the Florida Panhandle where it is endemic and state Endangered Bog gardens, rain gardens, restoration areas.

Based on BONAP maps, the ISB maps and specimens, and one author's personal observations, the range of this species appears to be those parts of the coastal plain and adjacent areas of sandhill where there are seepage wetlands.  The range extend from Mississippi to South Carolina.  It may be excluded from the southern half of the Florida peninsula temperatures unsuitable for its reproduction. This grows as a viney shrubl. Can be grown as a shrub if pruned but could also be trained against an arbor or post.
