This is a wetland plant. It is rarely grown, but it has potential in appropriate sites. Specimen plant or background screen for wet places.

This is a rare species and it should only be acquired from reputable plant nurseries. Some botanists have declared this endemic species to be a synonym for false rosemary (C. canescens), but since the populations are widely separated, we are treating them separately. Can be used as a medium-level groundcover or border plant.

Rear of garden as a screen.  Native meadows.

Wind pollinated.  Dioecious.  According to Huegel (2010), the flowers attract insects. Plant tree in areas where fallen fruit will not be an issue.

Salt tolerance has not been studied but it has been recorded (in New England) in salt marshes, suggesting tolerance of at least brackish water and likely tolerance of some salt spray. Information is lacking regarding pollination for the species. However, the family exhibits flowers that are hermaphrodite, dioecious, or gynodioecious (fairly commonly), and is most often pollinated by insects, (bees, butterflies & moths, or flies).  Also has cleistogamous flowers,so self pollination may also occur(Collins 1976 as cited in New England Native Plant Trust, 2002). Wildflower garden. It blooms early before most of the other wildflowers.
