The variety «Wolga» (Scorpion Weed in English-language registers) is a tetraploid form (4x) of Phacelia tanacetifolia. The plant is characterized by blue flower color.
In available official publications, the variety is mentioned primarily in the context of registry lists and methodology for trait description. Detailed morphological indicators, vegetation period data, and specific agronomic characteristics are absent from open sources.
