Common names: Longleaf spiderwort, Sandhill spiderwort

Taxonomic notes

Synonym: Tradescantia longifolia Small

The specific epithet roseolens is derived from the fragrant tea-rose smell emitted from the flower.[1]

Description

A description of Tradescantia roseolens is provided in The Flora of North America.

T. roseolens is similar to T. longifolia; however, T. roseolens can be differentiated by having smaller fragrant flowers and glandless stems.[1]

Distribution

Alabama, Florida, Georgia, and South Carolina. It is listed as imperiled in Georgia.[2]

Ecology

Habitat

Habitats of T. roseolens include Florida rosemary balds, oak scrubs, hammocks, sandhills, pinewoods, and roadsides.[3][4] Associated species include Ceratiola, Quercus inopina, Q. geminata and Q. chapmanii. In Florida rosemary balds, T. roseolens was found to be positively associated with patch isolation.[5]

Phenology

Flowers February to August.[3]

Fire ecology

Long periods of fire suppression can hinder the response of ephemeral, resprouting/seeding herbs such as T. roseolens. Fire has been observed to revitalize populations in recently burned sites.[6]

Pollination

The stamens have scent-producing hairs that attract pollinators. T. roseolens has 6 pollen baring anthers, allowing several flies to feed simultaneously on one flower. Deyrup (1988) observed that P. punctipennis was the most abundant insect on T. roseolens at Archbold Biological Station.

The following Hymenoptera families and species were observed visiting flowers of Tradescantia roseolens at Archbold Biological Station: [7]

Halictidae: Lasioglossum nymphalis, L. placidensis, L. puteulanum
