Substratum: soil.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa, next to Trenta 2b cottage, East Julian Alps, Posoje, Slovenia EC.Comment: Almost all species of Mulleins growing in Slovenia (13 all together) are all stout, beautiful plants. Verbascum nigrum is not the largest one of them, yet it can grow up to 1.2 m tall. Usually it has a single flowering stem with many, many bright yellow flowers, but smaller side flowering stems are also quite frequent. They branch always low on the main stem (contrary to the most of others species, like Verbascum lychnitis or Verbascum pulverulentum). During anthese (flowering period) the flowers do not open, as it is usual with most of long elongated inflorescences, 'systematically', from the bottom to the top of the inflorescence (or vice versa), but open sporadically, here and there, without respect to their position in the inflorescence, like a 'slow motion' firework.Verbascum nigrum is a common plant distributed almost all over the Europe. It can easily be separated form other species in this genus. It is the only yellow blooming one, which has violet densely hairy stamens and cordate (heart-shaped) base of ground leaves.
