Limonium carolinianum — Carolina sea-lavender

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

The flowering stalks of Carolina sea-lavender are often harvested from sheltered intertidal areas or from salt-marshes for making wreaths. Unfortunately, this can deplete populations of this rather slow-growing plant. Salt glands on their leaves permit sea-lavender to withstand saline environments.

Habitat

Brackish or salt marshes and flats, coastal beaches (sea beaches), marshes, intertidal, subtidal or open ocean
