Rank Reasons
Hypericum fasciculatum is a shrub that is endemic to the southeastern United States where it is restricted to the Coastal Plain from North Carolina to Florida and west to southern Mississippi, and eastern Louisiana. It is common in Florida and Alabama and found in a variety of habitats.
Range Extent Comments
Hypericum fasciculatum is endemic to the southeastern United States where it is restricted to the Coastal Plain from North Carolina to Florida and west to southern Mississippi, and eastern Louisiana (Weakley and Southeastern Flora Team 2022, FNA 2015). Range extent was calculated with GeoCAT using occurrence and photo based observation data (GBIF 2022, iNaturalist 2022, Bachman et al. 2011). This species is exotic is Alabama; it was introduced as a weed in a wetland mitigation planting mix in Arkansas (D. Soteropoulos, pers. comm., 2022).
Occurrences Comments
It is common throughout Florida and Alabama but uncommon to rare throughout the remainder (Weakley and Southeastern Flora Team 2022). Based on NatureServe Network occurrence data, herbarium records, photo-based observations, and anecdotal evidence, there are likely over 300 occurrences rangewide (GBIF 2022, SEINet 2022, iNaturalist 2022, NatureServe 2022).
