The study refers to an Asteraceae taxa – Serratula bulgarica Acht. & Stoj., a very rare species in the flora of the Republic of Moldova, reported only in the phytocenoses of Quercus pubescens Willd. in the vicinity of the Batîr commune in the Cimișlia district, whose actual number does not exceed 50 phytoindividuals. This is a Critically Endangered taxa, protected by law, included in the Red Book of the Republic of Moldova, 3rd ed., the 1997 IUCN Red List of Threatened Plants. For the conservation and multiplication of the Serratula bulgarica species in ex situ conditions, fragments of rhizomes collected in natural habitat in the autumn of 2022 were planted in the experimental plot. Ex situ the species develops well, goes through all ontogenetic stages, forms a vigorous habitus. The seeds are viable and the germination rate in laboratory conditions is about 90%. Vegetative propagation by plantlets from renewal buds on rhizomes is high.
