Here is the best article I could find on this.
The Greens' surge in popularity comes after the party on Monday named co-chair Annalena Baerbock, 40, as its first candidate for chancellor. The nomination of Ms Baerbock, a centrist who advocates a greener economy and a tougher foreign policy stance on Russia and China, has been widely praised.

Well they are in a coalition in Berlin (SPD, Grüne, Linke)
They also refused to be in a coalition with them on the federal level. The SPD preferred being the smaller party in a coalition with the conservatives over getting to be chancelor in a left coalition. Twice.
Partially this is because the SPD is the most cucked party in existence. Even moreso than the Dems or Labour. Partially, this is also because the Linke challenges US foreign policy, which is still a taboo in German politics, in spite of the US regualrly setting its pants on fire, being the most aggressive regime in the world, and also in total disregard of public opinion in this country, which is very clearly anti-war. 70% of the people here were against invading Afghanistan. 70%. The SPD and Greens went there regardless.
