Resumen de Reports of some ornamental plants as aliens for the Bulgarian flora

Antoaneta S. Petrova, Vladimir Vladimirov

• The aim of the paper is to report data about the distribution, habitat preferences and naturalisation success of three ornamental taxa cultivated in Bulgaria. Hemerocallis fulva (Asphodelaceae), a native species to temperate Asia, has been recorded as an established alien in eight floristic regions in the country. Oxalis articulata (Oxalidaceae), native to temperate South America, has been recorded as a casual species in three floristic regions. Phalaris arundinacea var. picta (Poaceae) has white variegated leaves and is a popular garden cultivar of a native to Bulgaria species. It has been recorded as an established alien in three floristic regions.

  Although H. fulva and Ph. arundinacea var. picta may form relatively wide, monodominant stands through vegetative reproduction, at this stage the two taxa do not show invasive behaviour in the Bulgarian flora.

  Photographs and distribution maps of the species are provided.
