Solanum elaeagnifolium (Solanaceae) is reported as a new alien species to the Bulgarian flora. It is native to Central America – Mexico and USA, and has been introduced and naturalized in 4 continents. The species was recorded in Valley of River Struma floristic region in Bulgaria, along the road from Sandanski to Petrich town. Inferring from its current occurrence in the country it can be said the taxon had been recently introduced, and is likely to naturalize and spread further due to its invasive traits and suitable environmental conditions in the region. The article presents brief morphological description of the species based on the material collected in the field, and discussion of its habitat preferences and invasiveness.
