Flowering During January in Antigonish County, Nova Scotia

David J. Garbary, Barry R. Taylor


Over 85 records of 23 species of blooming, herbaceous angiosperms were made at 19 sites in Antigonish County between 7 and 21 January 2006, when daytime temperatures reached 15°C. These observations followed an unusually warm fall and early winter. All species were observed on waste ground or in fields and garden plots, except for Epigaea repens L. which was part of ground vegetation in a sparsely wooded site. The primary families represented were Asteraceae (six species), Brassicaceae (six species) and Carophyllaceae (four species). The most commonly observed plants were Taraxacum officinale (L.) Weber (11 sites), Capsella bursa-pastoris (L.) Medik. (nine sites), Thlaspi arvense L. (three sites) and Stellaria media (L.) Vill. (four sites). Many plants and inflorescences were conspicuously frost-damaged, and flowers were rarely fully open. In several species, e.g., T. arvense and Cerastium vulgatum L., many individual plants looked normal and there was no evidence of frost damage. These observations are the latest flowering records for Nova Scotia.
