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.
