The bugloss species Echium russicum in our Caucasus. It is a meter-tall plant with a long spike increasing every year, and with a strange crimson-brownish colour. It is surrounded by many larkspurs and many bluebell species.
The fringed pink (Dianthus superbus) in our Arctic Valley. In Norway it only grows in northeastern Finnmark.
And to those with special interests: In the middle of the Siberian slope there is a strange composite forming a rosette with completely sessile capitulas (= heads of numerous small flowers). It is the Central Asian Inula rhizocephala.
