Taxonomic Notes

Synonyms: Neopieris mariana (Linnaeus).[2]

Varieties: none.[2]


L. mariana is a perennial shrub of the Ericaceae family that is native to North America.[1] It is distinguishable by broadly elliptic leaves that grow at an upward 45-degree angle and bright pink axillary buds.[2]


L. mariana ranges from Rhode Island and New York, south to the central peninsular and east Panhandle Florida. There are disjunct populations west of the Mississippi River in southcentral Missouri, central Arizona, northwestern Louisiana, southeastern Oklahoma, and eastern Texas.[2]



Common habitats for L. mariana are pine flatwoods, savannas, pocosin-sandhill ecotones, and dry sandy woodlands.[3] These habitats largely occur in the Atlantic and Gulf Coastal Plain, Eastern Mountains, Great Plains, and the Northcentral and Northeast of the United States.[1] Specimens have been collected from habitats including dry sand oak woodland, pine flatwoods, thickets, dry sands in pine woodlands, wet flatwoods, dry sands near small ponds, cypress swamp edges, lakeside sand ridges, and pine palmetto flats.[4]


Lyonia mariana has been observed to flower from April to August, with peak inflorescences in May.[5]

Fire ecology

Populations of Lyonia mariana have been known to persist through repeated annual burns.[6]


Lyonia mariana is visited by long-tongued bees from the Apidae family such as Nomada ovata.[7]

Conservation, cultivation, and restoration

L. mariana has been classified as endangered in Pennsylvania, special concern in Connecticut, and historical in Rhode Island.[1]
