The Wild Plant Society Newsletter reports that sea lavender (Limonium carolinianum) has been added to the list of plants protected by Rhode Island's "Christmas Greens" law. The law also prohibits collecting of club mosses (Lycopodium spp.), flower­ ing dogwood, trailing arbutus, great laurel ( maximum), mountain laurel, winterberry (!lex verticillata), American holly (1. opaca), and inkberry, along with pines, hemlocks, cedars, spruces, and firs. As sea lavender has become more popular in holiday decorations and dried flower arrangements, collectors have devastated populations in Atlantic seaboard salt marshes. This prompted Leona A. Kelly, a Rhode Island Wild Plant Society member and state representative, to introduce the bill. As with the other "Christmas Greens" plants, sea lavender can now Luce Garden features formal boxwood knots. be collected only by the property owner or with written permission of the property owner.
